Liking this shape a lot. Are you working alone? Comes together fast, or seems to have.

[Johan R]

It's probably going to outlast the boat but why risk it if you don't need to.

You are right. A friend would also say why risk sailing on a boat when you could possibly drown? We all make our choices.

Maybe plastic nail/brads could be used as clamps for joints and left in. I can not imagine buying a lot of clamps for a single project. Toplicht in Germany sells bronze fastenings, it is a lot of beer money.

The whisky plank is on and the whisky has been shared around

I think well worth the extra effort over the 3 plank a side version; without doubt. Has the material list for the hull been accurate?

Looking great Steve . Thanks for an excuse to have a sip.

Yes it's looking much nicer than originally drawn. The materials list applies mainly to the original plan so it's a bit hit and miss but I'm thinking it's fairly close

Looking great Steve . Thanks for an excuse to have a sip.

Glad to be of service

Compliments on your shop!

Sorry I missed that question. The boat shed consists of many retirees from many walks of life and I have a couple of shipwrights, carpenters and general maintenance types working with me on this.

It's a group thing similar to the "mens shed" setup and was originally the female ablutions block at the Catalina base that occupied the site during WW2. You can see the "Catalina" (Oughtred St Ayles Skiff) in some of the pics as well as an Oughtred Acorn, these were built here by members for members to row which happens twice a week.

While there is a lot of fiddly stuff going on with the hull some of the guys have moved onto other tasks like laminating cabin top beams. I've opted for a curved top rather than the three flat panel version as drawn. We are raising the cabin sides by 60mm to give a more pleasing arch without sacrificing head room.

I have heard of celery top and hoop pine, but not familiar with Australian white woods. Which species are you using for those laminated beams?

[Steve TN 15]

All the soft wood in this will be hoop pine, it's affordable, reasonably straight grained and clear of knots.

[Johan R]

I read Hoop Pine is classed as "non durable", just like Okume. Always seemed odd to me that a "marine grade" plywood is based on the quality of the veneers and the glue used, rather than the life span of the timber species used. $250 Auz for a 12mm sheet of hoop pine marine ply. Epoxy saves the day i suppose, even Baltic Birch plywood has been used in hull construction.

Yes. And radiata pine, too. For a small boat that will live on a trailer in a garage, built with epoxy techniques, I've found that these are perfectly practical choices. My brother's glued-lap 15' boat used baltic birch and is now 12 years old. My strip-planked boat used radiata, 6 years old. I don't think the "non-durable" label means as much with these kinds of boats as it would for a traditionally planked hull. Or for a boat that will live on a mooring, maybe.
