O'Day Daysailer restoration

by Example Logs · boatbuildlog.com

An example restoration log. Shows how a restoration diverges from a new build: survey and teardown first, and a scope that grows once you open things up.

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.

Survey & Assessment 4 h

What I actually bought

Bought for very little, which should have told me something. Moisture meter reads high right through the aft deck and the centreboard trunk weeps.

Writing the honest scope down now so I can compare it to reality later.

Teardown 8 h

Everything off

Stripped all hardware, bagged and labelled by location, photographed before removal.

The photographs are the point. Six months from now I will not remember which of the three similar bolts came from where.

Deck & Cabin 15 h

Deck recore — scope grew

Cut the top skin, dug out wet balsa, dried the cavity, rebedded new core.

The wet area was roughly twice what the meter suggested. That is normal and worth budgeting for: assume the damage is bigger than the survey.

Hull & Plank Repair 11 h

Centreboard trunk

Old sealant had failed along the trunk. Ground out, reglassed, faired.

Slow, awkward, upside-down work. Two hours at a time was my limit.

Gelcoat & Glass Repair 10 h

Blisters and crazing

Ground out blisters, filled, faired the topsides. Crazing round the old cleat bases came out with the hardware.

Still to do: paint, then rig and hardware. Roughly 48 hours in so far against an estimate of 30.
