Making a Stitch & Glue Plywood Kayak Video Instruction
We are building a plywood (stitch & glue) kayak, you can Digital Plans Patterns and build it from scratch using these instructions. In this case we started from The Petrel Play SG kit from Chesapeake Light Craft which comes with a comprehensive instruction manual. You can think of this Instructable as a supplement to that manual.
For the visual learner, this comprehensive series of over 30 videos will bring you step-by-step through every aspect of the project, from unboxing the kit to launching the completed kayak. While this instruction is based on the Petrel Play SG kayak kit from Chesapeake Light Craft, the skills, techniques and procedures are adaptable to any Stitch and Glue Kayak design.
The videos are supplemented with still photography of the process. Note that these photos were taken during a different built so some aspects may be slightly different, but this should give you a sense of some alternatives available.
These instructions include video showing the plywood kayak building process in detail as well as an outline of what is being done in each video. This project was completed in about 21 days in the shop. Most of those days involved about 5 hour of work for a total of about 100 hours to complete the build.
You can take each step as a goal to accomplish in one session in the shop, however some of the steps are actually dividing one day of actual work into several steps so you may be able to do a couple of steps a day if you have the time to be in the shop.

Outline for Building a Stitch and Glue Kayak
About the Petrel Play SG
The Petrel Play SG represents years of my experiencing designing kayaks, trying to find the optimal compromise between an easy kayak for a novice kayaker to paddle and a kayak that a skilled kayaker can have a lot of fun paddling. It is a blend of traditional kayak craftsmanship and modern design advancements.
The design’s roots trace back to the early 2000s, where the initial prototype of the Petrel was conceived. Nick refined the design over years of practical use and feedback, evolving it from his previous creations within the renowned Night Heron family of kayaks. This continuous evolution focused on achieving a blend of stability, maneuverability, and ease of handling, aimed at enriching the paddling experience in various water conditions.
The primary goal behind designing the Petrel Play SG was to craft a vessel that introduces newcomers to the world of kayak building without overwhelming them with complexity. By employing the stitch and glue construction method, the Petrel Play SG kit simplifies the building process while still retaining the professional finish and performance expected of a high-quality craft.
This kayak design caters to a wide audience—ideal for beginner paddlers looking to explore calm bays and lakes, as well as more experienced enthusiasts eager to navigate challenging wave environments. With its thoughtful balance between length and width, the Petrel Play SG offers superior stability and agility, making it a suitable choice for recreational exploration and advanced paddling adventures alike.
If you are starting from the Chesapeake Light Craft (CLC) Kit you will receive several boxes containing all the materials you will need. As you unload the boxes you should do an inventory to assure all the pieces are included and start to familiarize yourself with the bits and pieces.
If you are not building from a kit, please look at my "Making a Plywood Kayak" Instructable. You will need accurate plans so you can cut out the plywood panels precisely.

Note: These instructions assume you are working with a Chesapeake Light Craft kit for the Petrel Play SG Sea kayak. For detailed specifications and additional support, refer to the kit documentation or contact Chesapeake Light Craft directly.
Wire Stitching for Kayak Hull Assembly
Required Materials
- Copper wire
- Pliers
- Utility knife (for removing tabs if needed)
Preparation
- Ensure all panels are roughly positioned in their final configuration
- Remove any remaining tabs on panel edges using a utility knife or block plane
- Verify that stitch holes between panels align properly
Basic Stitching Technique
- Align holes between two adjacent panels
- Insert copper wire through aligned holes
- Cross wires at approximately 90° angle on the inside of the hull
- Pull wires firmly to create tension (don't rely on twisting to create tension)
- While maintaining tension, twist wires together to lock in place
- Ensure wires are crossed at 90° before twisting
- The twist should be tight and compact, not long and parallel
Main Assembly Process
- Begin with a few initial stitches to roughly position panels
- Start at key points like stems or intersections
- Don't fully tighten these first stitches
- Work systematically along seams
- Align panel edges for smooth transition
- Focus on achieving a clean seam on the outside of the boat
- Add stitches approximately every 6 inches
- You can skip occasional holes if the seam is tight and well-aligned
- Handle problem areas
- If panels won't align, check for:
- Interfering stitches from forms
- Hidden tabs
- Missing holes (drill new ones if needed)
- For stubborn gaps, use closer stitch spacing (every 3 inches)
- Bow and Stern Assembly
- Use extra stitches near the ends where panels come together
- Pre-bend wires to reach difficult angles
- Focus on pulling panels together by hand before securing with wire
- Small gaps are acceptable as they'll be filled with epoxy later
Troubleshooting Tips
- If seams keep popping apart:
- Add more stitches in the area
- Check for and remove any constraining stitches to forms
- Ensure proper wire twisting technique
- For difficult-to-reach holes:
- Pre-bend wire to match the required angle
- Use longer wire pieces for better manipulation
- For gaps in the seam:
- Try repositioning nearby stitches
- Add additional stitches if holes are available
- Remember that small gaps will be filled with epoxy later
Quality Checks
- Exterior seams should be smooth with minimal stepping between panels
- Panels should maintain alignment along entire length
- Wire twists should be tight and secure
- Hull shape should be symmetrical and true to design
Important Notes
- Don't obsess over perfect seams; small gaps will be filled with epoxy
- Focus on outside seam appearance rather than inside appearance
- Stitches are temporary and will be removed after gluing
- Work at a relaxed pace to ensure proper alignment
- All stitches don't need to be fully tight initially; gradual tightening helps maintain proper shape
Spot Welding Kayak Hull Panels With CA Glue
This guide covers the process of spot welding stitched kayak panels using cyanoacrylate (CA) glue, following Nick Schade's method for the Petrel Play SG sea kayak.
Required Materials
- Cyanoacrylate (CA) glue / Super glue
- CA activator spray
- Protective gloves (recommended)
Pre-Welding Inspection
- Check all seam alignments by feel from the outside of the hull
- Run your hands across each seam
- Seams should feel smooth and continuous
- No snagging or overhanging edges
- If problematic areas are found:
- Remove wires if necessary
- Realign panels
- Re-stitch as needed
Spot Welding Process
- Start with one seam at a time
- Apply CA glue:
- Place small dots every 2 inches along seams
- Use approximately 1/8 inch (3 millimeter) sized dots
- Insert glue tip directly into the seam
- Avoid excess glue running down panels
- Don't fill entire seams:
- Leave room for later epoxy application
- Use minimal glue - just enough to hold panels
Special Areas
Stem and Stern
- Apply glue carefully into seams where panels meet
- Allow glue to drip down into tight spaces
- Use activator spray to cure
- Be careful not to oversaturate with glue
Chine Joints (Where Panels Merge)
- Align panels for best fit
- Accept small gaps (approximately 1/16 inch) where sheer lines taper
- Apply glue as normal
- Hold panels in alignment until cured
Non-Beveled Areas
- Flex panels slightly to expose seam edge
- Apply glue to top edge of seam
- Realign panels
- Hold firmly until cured
- Use activator spray from accessible side
Tips and Techniques
- Feel free to apply pressure to align panels:
- Don't be afraid to use force when needed
- Wood is more flexible than it appears
- If seams aren't aligning:
- Apply steady pressure
- Hold position while applying glue
- Use activator to cure quickly
Important Notes
- This is temporary holding - not final structural bonding
- Maintain boat on workbench after spot welding
- Don't transport boat at this stage
- Later steps will include:
- Wire removal
- Interior fillets
- Fiberglass application
Quality Checks
- Verify all seams are spot welded
- Check for smooth transitions across all seams
- Ensure no loose areas remain
- Confirm stem and stern are securely bonded
Common Issues and Solutions
- Glue on fingers: Use activator to cure immediately. Debonder is available if you mess up.
- Wire interference: OK if some wires get glued, they'll be removed later
- Uneven seams: Slight wiggles can be smoothed during later sanding/planing
- Gaps: Apply pressure while gluing to minimize
Next Steps
After spot welding is complete:
- Allow all glue to fully cure
- Prepare for wire removal
- Plan for interior filleting
- Prepare for fiberglassing
Filleting Stitch and Glue Seams - Kayak Hull
Materials and Prerequisites
Required Materials
- Epoxy resin and hardener (MAS brand recommended)
- Wood flour (fine sawdust, MDF-based)

- Tongue depressor (optional)
Environmental Requirements
- Work area temperature above 65°F
- Well-ventilated space
Safety Precautions
- Wear protective gloves at all times when handling epoxy
- Wear long sleeves and long pants
- Ensure adequate ventilation
- Be aware that epoxy creates an exothermic reaction (generates heat)
- Keep hands clean to avoid getting epoxy on the outside of the boat
Pre-Fillet Preparation
- Remove wire stitches:
- Clip wires from the inside
- Pull wires out through the holes
- Cut flush if wires are stuck with glue
- Leave only those at the top of the forms
- Sand down spot-weld bumps ("nubbins"):
- Use 120-grit sandpaper
- Sand with the grain
- Focus on areas under seats and visible areas
- Clean thoroughly:
- Vacuum out all debris from boat interior
- Ensure working surface is clean and clear
Epoxy Mixing Process
Preparation
- Warm up epoxy (optional but recommended):
- Use heat lamp or terrarium heating pad placed near epoxy containers to reduce viscosity
Basic Epoxy Mix
- Ensure pumps are primed
- Use Proper ratio of resin to hardener: With MAS epoxy 1 pump to 1 pump produces the appropriate 2:1 ratio
- Start with resin (blue pump)
- Add hardener (red pump)
- Mix thoroughly for at least 1 minute
- Scrape sides and bottom while mixing
Creating Fillet Mixture
- Start with small batch for practice (enough for a couple feet)
- Add wood flour gradually:
- Begin with equal volume of wood flour to epoxy
- Mix slowly to avoid dust
- Add more wood flour 1-2 scoops at a time
- Final consistency should be like natural peanut butter:
- Should hold its shape but still be workable
- Should not be too shiny
- Should stay upright on mixing stick
Applying Fillets
Preparation
- Transfer mixture to application bag:
- Place mixing bag in supporting container
- Transfer mixture to piping bag or zip-lock
- If using zip-lock, cut corner for ~1/4 inch opening
- Twist top of bag to prevent backflow
Application Process
- Pipe approximately 1/4 inch bead along seams:
- Focus on panel joints
- Apply more material to deeper seams
- Apply less to flatter seams
- Work quickly (15-minute working time)
Shaping the Fillets
- Use plastic spoon or tongue depressor:
- Place finger inside spoon for control
- Press down into fillet
- Make one long, smooth stroke along seam
- Avoid multiple short strokes
- For squeeze-out cleanup:
- Use squeegee with slight upward angle
- Work lengthwise along seams
- Allow excess to accumulate on squeegee
- Return excess to mixing bucket
- For stem areas (bow and stern):
- Apply generous amount of mixture
- Press deep into narrow points
- Create substantial fillet for structural strength
- Smooth carefully
Finishing and Quality Control
Final Smoothing
- Remove any "goobers" (hard chunks or excess material)
- Use denatured alcohol on fingertip to smooth rough spots:
- Apply light pressure
- Work in one direction
- Aim for approximately ½-inch wide fillets
Quality Checks
- Ensure no light shows through gaps
- Check for consistent fillet width
- Verify smooth transitions between panels
- Confirm adequate filling in stem areas
- Look for and remove any remaining bumps
Preparation for Next Steps
- If glassing same day, fillets should still be wet
- If glassing different day:
- Allow fillets to cure completely
- Sand fillets to remove gloss and high spots
- Ensure all surfaces are smooth for proper glass adhesion
Important Tips
- Start with smaller batches until familiar with working time
- Work from comfortable positions for best results
- Keep hands clean, use back of hand if needed to hold boat
- Monitor room temperature - warmer temperatures reduce working time
- If epoxy mix fails to cure, remove completely before applying glass
- Always pre-mix epoxy thoroughly before adding wood flour
- Clean mixing containers for reuse

1. Cloth Layout
- Prepare the cloth:
- Cut pieces to fit across boat width
- Allow 2-3 inches excess on each side
- Start from cockpit area
- Plan for 1-inch overlaps between pieces
- Position the cloth:
- Overlaps should face away from brushing direction
- For bow/stern: cut triangles at 45° angle (bias cut)
- Use dry chip brush to smooth into seams
- Avoid snagging cloth on plywood edges
2. Epoxy Application
- Mixing epoxy:
- Make small batches (¾ inch in cup)
- Mix only what you can use in 10-15 minutes
- Keep batches small to prevent overheating
- Application technique:
- Start from middle, work outward to sides
- Use brush to distribute epoxy
- Work wet to dry areas
- Keep moving at steady pace
- Don't revisit wet areas
- For bow/stern: brush on rather than pour
3. Problem Management
- Dealing with bridges (lifted areas):
- Don't fix immediately
- Address after initial wetout
- Usually indicates insufficient cloth in seam
- Lift edge and ease cloth down
- Managing wrinkles:
- Side-to-side wrinkles: pull yarns lengthwise
- Vertical wrinkles: pull toward end of cloth
- Work wrinkles toward dry areas
- Don't force cloth - persuade it
4. Grunge Cupping Process
- Preparation:
- Cut small slit in paper cup
- Ready clean squeegees
- Technique:
- Hold squeegee at 45° angle
- Apply moderate pressure
- Draw excess epoxy through cup slit
- Look for cloth texture (matte vs. shiny)

- Continue until excess removed
5. Final Steps
- Edge inspection:
- Check all top edges for dry spots
- Trim excess hanging cloth
- Ensure good adhesion along edges
- Final fixes:
- Address remaining bridges
- Fix persistent wrinkles
- Ensure complete wetout
Critical Tips
Best Practices
- Work quickly but deliberately
- Don't perfect each area before moving on
- Less epoxy is better than too much
- Keep epoxy batches small
- Always work wet to dry
- Avoid repeated squeegeeing
- If technique isn't working, try different approach
Common Mistakes to Avoid
- Overworking areas
- Using too much epoxy
- Letting epoxy overheat in cup
- Fixing problems too early
- Working too slowly
- Excessive brushing
Safety Notes
- Ensure proper ventilation
- Wear appropriate protective equipment
- Keep cleanup materials ready
- Monitor epoxy temperature
Next Steps
After initial cure (typically 2-4 hours):
- Inspect surface for problems
- Consider applying fill coat for:
- Evening out surface
- Providing sanding layer
- Preparing for varnish
Note: This process is one of several fiberglassing sessions required for complete kayak construction. Interior work is typically most challenging due to gravity working against you. Future sessions will include outside hull, inside deck, and outside deck.
Stitch and Glue Kayak Deck Construction
Interior Hull Preparation
- Apply fill coat to the interior fiberglass
- Purpose: Prevent humidity migration through pinholes
- Mix small batch of epoxy (½ to ¾ inch in cup)
- Apply thin coat over entire interior surface
- Goal: Fill weave partially while maintaining some texture for varnish adhesion
- Trim Excess Fiberglass
- Hold sharp utility knife flush against wood edge
- Draw knife through fiberglass in one smooth motion (avoid sawing motion)
- Trim flush to wood surface
- For top edge bevels, trim from outside
- Remove any bubbles or drips near edges by shaving flush to surface
Deck Panel Assembly
- Prepare Puzzle Joint Assembly
- Identify all deck panels (side panels, front deck, foredeck, back deck, cockpit recess)
- Orient panels with inside facing out
- Match beveled sides
- Verify proper alignment of puzzle joints
- Assemble Puzzle Joints
- Ensure panels are as flat as possible
- Apply CA glue (super glue) to one side
- Apply accelerant to mating surface
- Join pieces together quickly
- Hold firmly until bond sets
- Check alignment by sighting down seam for smooth curve
- Quality Control Checks
- Sight down seams for smooth, continuous curves
- Check for gaps in joints
- Verify proper alignment of panels
- Look for any "knuckles" or irregularities in curves
Fixing Misaligned Joints
- Disassembly (if needed)
- Apply CA glue debonder solution to glue joints
- Allow solution to penetrate
- Carefully separate panels
- Mark any breaks or damage for repair
- Joint Cleanup
- Use nail files or sandpaper to clean glue residue
- Maintain flat edges (avoid rounding)
- Clean until fresh wood is visible
- Be careful not to oversand or create gaps
- Reassembly
- Test fit panels before gluing
- Start assembly from opposite end if initial attempt was tight
- Apply generous amount of glue
- Use accelerant on mating surface
- Join firmly and hold until set
- Check final alignment
Tips for Success
- Wear gloves when working with epoxy and glue
- Don't hesitate to take decisive corrective action if alignment is wrong
- Clean joints thoroughly rather than making minimal adjustments
- Remember that fiberglass and epoxy will add structural integrity to repairs
- Sight down seams frequently to check alignment
- Be patient with puzzle joint alignment; they may require specific orientation
Final Notes
- Small gaps in puzzle joints are acceptable if not excessive
- Broken pieces can be reglued and will be strengthened by exterior fiberglass
- The deck will require additional work for hatch recesses in subsequent steps
- The interior will eventually benefit from varnish for UV protection
Note: This document covers only the initial deck assembly phase. Additional steps for hatch recess installation and final finishing will follow in subsequent procedures.

- Should not freely pour off stirring stick
2. Piping Bag Preparation
- Place bag in cup and fold edges down
- Transfer epoxy mixture into piping bag
- Cut tip to create approximately 1/4 inch opening
3. Applying Fillets
- Insert tip into seam
- Apply enough pressure to create white lines on either side of bead
- Maintain consistent pressure for uniform application
- Create continuous beads along all seams
- Pay special attention to:
- Cockpit area
- Hatch openings
- Puzzle joints
4. Shaping Fillets
- Select appropriate radius tool for area
- Larger tools for flatter angles
- Smaller tools for tighter angles
- Apply firm pressure to create proper fillet shape
- Look for white lines on either side of fillet
- Adjust tool angle to modify apparent radius when needed
- Make multiple passes if necessary to achieve desired shape
5. Clean-up Process

- Create a flat spot approximately 1/4 inch (6mm) wide
- Keep plane level and work along entire keel line
- Stop before bow and stern where curve becomes too steep
- After creating flat spot:
- Plane each edge at 45 degrees to create rounded profile
- Check smoothness with hand
- Avoid over-planing
4. Round Over the Chines
- Similar to keel line process:
- Hold plane halfway between panel angles
- Create 1/4 inch wide flat spot
- Work carefully near stained areas
- Follow natural curve of chine
- Round over edges:
- Make smaller cuts to create smooth curve
- Check frequently with hand
- Maintain even width along length
5. Shape the Stems (Bow and Stern)
- Plane stems to create initial shape:
- Work until epoxy fillet becomes visible
- Stay at least 1/4 inch from stitch holes
- Create straight, even line
- Round over stems:
- Create series of flat spots around curve
- Blend spots together into smooth curve
- Make radius larger for easier fiberglassing
- Check frequently with hand
6. Final Surface Preparation
- Sand bare wood areas:

Fiberglassing Kayak Combing and Keel Strips
Materials Needed
- 4 oz fiberglass cloth
- Epoxy resin and hardener
- Scissors
- Paper cups
- Squeegee
- Gloves
- Clean rags
- Wide workbench or flat surface
Preparation Steps
Cutting Fiberglass Strips
- Roll out fiberglass cloth on a clean, wide surface
- Cut strips approximately 4 inches (8 cm) wide at a 45° angle (bias cut)
- Follow the diagonal lines visible in the fabric weave
- Strips should be long enough to wrap around the cockpit combing
- Carefully trim diagonal ends
- Gently fold strips and set aside in a safe place
Important Handling Notes
- Never pull or tug on the bias-cut cloth
- Avoid holding the cloth directly while cutting
- Handle strips delicately to maintain their shape
- Do not disturb the weave pattern
Application Process
Mixing Epoxy

- Allow to cure completely
Tips and Warnings
- Work in sections if needed rather than attempting entire circumference at once
- Overlap pieces by 1-2 centimeters where sections meet
- Clean excess epoxy immediately to reduce sanding later
- Multiple thin layers are better than one thick layer
- 4 oz cloth requires two layers for similar protection as one layer of 9 oz cloth
- Wood is tougher than it appears - don't be overly gentle during application
Next Steps
- Allow complete curing
- Sand entire boat surface
- Apply fill coat
- Sand again
- Apply varnish (multiple coats with sanding between)
Note: This process applies to both the combing and keel strip areas of the kayak. Bias-cut cloth is superior to pre-woven tape for conforming to curved surfaces.
Fairing and Fill Coating a Kayak
Important Concepts
- Fairing vs. Sanding: The goal is to level the surface, not just sand it. Focus on bringing down high spots to match low spots.

2. Main Fairing Process
- Attach 60-grit sandpaper to long board
- Create dust collection holes if using vacuum system
- Sand in the following manner:
- Keep the tool flat against the surface
- Never sand across chines or edges
- Work in systematic sections
- Continue until either:
- All shiny spots are gone, or
- Fiberglass texture begins to show
3. Special Areas
- Puzzle Joints:
- Sand carefully to avoid breaking through
- Stop when glass texture first appears
- Accept some remaining shine rather than oversanding
- Chines and Edges:
- Avoid sanding these areas with coarse grit
- Save for final sanding with 100-120 grit
- Maintain edge integrity
- Narrow Areas:
- Use smaller sanding block
- Maintain careful control near edges

4. Surface Preparation for Fill Coat
- Use Scotch-Brite pad to de-gloss remaining shiny areas
- Light pressure
- Cover entire surface
- Pay special attention to corners
- Clean Surface:
- Vacuum thoroughly
- Wipe down with denatured alcohol
- Check for flaws (scratches that remain visible after alcohol wipe need attention)
5. Fill Coat Application
- Prepare the Boat:
- Position boat at angle for optimal coating
- Apply masking tape 1/16" below seam lines
- Create drip edges by folding tape
- Prepare Tools:
- Clean chip brushes
- Use tape to remove loose bristles
- Optional: Apply super glue to ferrule to secure bristles

- Three-stroke method: a. Distribute: Horizontal strokes to apply epoxy b. Level: Vertical strokes to even out c. Tip-off: Light horizontal strokes to remove brush marks
- Maintain wet edge
- Avoid brushing across edges
- Optional: Use torch to remove bubbles
Tips for Success
- Don't rush the fairing process - it's crucial for final finish
- Watch for glass texture - stop sanding when it appears
- Small breakthroughs (dime-sized) are acceptable but not ideal
- Vertical surfaces need extra attention during fill coat
- Apply fill coat generously - thin coats are not always better
- Remove masking tape before epoxy fully cures
Next Steps
- Allow fill coat to cure
- Evaluate surface
- Determine if additional fill coat needed
- Proceed to finish sanding (80-120 grit)
- Begin varnishing process
Common Mistakes to Avoid
- Sanding through glass at puzzle joints
- Rounding over chines and edges

- Wipe entire surface with paint thinner
- Allow solvent to fully evaporate before varnishing
Varnishing Technique
Deck Application
- Start with combing area using small brush
- Switch to 2-inch foam brush for main surfaces
- Work in ~1-foot sections
- Apply in this sequence for each section:
- Horizontal strokes to apply varnish
- Vertical strokes to even out
- Horizontal strokes to tip off
- Work parallel to feature lines near chines
- Avoid dragging brush across sharp edges
- Maintain a wet edge between sections
Hull Application
- Work in sections between stitch holes
- Alternate sides every two sections
- Use three-stroke method:
- First pass: lay down varnish
- Second pass: even out (add or remove as needed)
- Final pass: tip off (remove excess)
- Be careful around skegs - avoid overflow
- Pay less attention to keel line (will get scratched with use)
Important Tips
- Replace sandpaper frequently for best results
- Save used sandpaper for hand-sanding touch-ups
- Filter varnish before application
- Work quickly to maintain wet edge
- Keep brush strokes parallel to feature lines near edges
- Don't varnish areas where hardware will be attached (hatch surfaces, etc.)
Quality Considerations
- This process aims for a good, protective finish
- Perfect mirror finish requires additional time and effort
- Focus on UV protection of epoxy
- Accept that some brush marks may be visible
- Prioritize even coverage over perfect reflection
Next Steps
