Shearwater 17 in a one-car garage

by Example Logs · boatbuildlog.com

An example log following a first-time builder through a stitch-and-glue kayak over seven months of weekends. Shows how much detail is worth recording.

This is an example log, not a real project. It exists to show what a useful build log looks like — dated entries, tagged to a step, with hours recorded and mistakes written down. The technique in it is illustrative; don’t follow it as instruction, and check anything structural against your designer’s drawings. Its hours are excluded from the site’s median figures.

Planning & Research 3 h

Ordered the kit

Went back and forth between this and a 16 for weeks. Settled on the 17 because I want to carry camping gear.

Worth writing down now: garage is 9 feet wide, boat is 17 feet long. Measured twice before ordering. The bench has to come out.

Shop & Tooling 5.5 h

Cleared the garage, built a strongback

Two sawhorses and a ladder frame from construction lumber, levelled with shims and a long spirit level.

The thing nobody mentions: you need to walk all the way round the boat. I lost a weekend to rearranging before I accepted that.

Hull Panels 7 h

Puzzle joints

Panels came pre-cut with puzzle joints. Dry-fitted everything first and labelled each piece with pencil on the inside face.

Mistake to avoid: I marked two panels on what became the outside. Sanding pencil out of okoume before varnish is not fun.

Stitch & Assembly 9 h

Wired the hull together

The moment it stops being a pile of plywood. Took most of a Saturday.

Wire tension is the whole job — too tight and the panels distort, too loose and the seams open. I went round three times adjusting before I was happy with the sheerline.

Fillets & Taping 8.5 h

Fillets and tape

Thickened epoxy fillets inside every seam, then glass tape over them.

Shop was 8°C and the epoxy took forever to kick. Ended up running a heater overnight. Temperature matters more than the instructions imply.

Glassing & Epoxy 11 h

Sheathed the hull

Cloth over the whole exterior, wetted out, then two fill coats over the following week.

Got blush on the first fill coat because I recoated too late. Had to wash and sand it back. Read the epoxy manufacturer's recoat window and set a timer.

Fairing & Sanding 16 h

Fairing — the long one

Sixteen hours across three weekends and it is still not perfect.

This is the step everyone under-photographs and under-estimates. Longboard, low-angle light, and accept that you will find another low spot every time you look.

Deck & Coamings 9.5 h

Deck on, hatches cut

Deck glued down and the hatches cut out. Suddenly looks like a kayak rather than a canoe.

Cut the hatch openings before glueing the deck if you can — reaching inside afterwards is awkward.

Paint & Finish 12 h

Varnish schedule

Six coats of varnish, sanding between. Deck bright, hull painted.

Dust is the enemy. Wet the floor before each coat and stop opening the garage door.

Launch Day 4 h

Launch day

Floats, tracks straight, and is faster than I can paddle it.

Total: about 96 hours over seven months. I had estimated 60. Nobody's first boat takes as long as the plans say, and that is fine.
