Beautiful work! She's going to be something to be proud of when you are done.

Thanks guys! I'm starting to get fairly confident that the end result will be worth the work...

It's marine glued teak veneer plywood, 14 and 16mm. 1 mm of teak veneer and the rest is probably fir glued with something water-resistant. Apparently the big guys at some local reputable boat manufacturers use the same. I really hope it works well, at least it is expensive and heavy. The whole thickness has 10 plies, I guess it's a good thing?

Perfect opportunity for a question:

Would you a) varnish or b) oil or c) wax or something else the plywood indoors? Some parts need to take some water spray while showering, but otherwise dry?

Not sure what I would use but I would definitely seal all cut/exposed edges. Water has a funny way of making its way in a marine environement. Not to mention molds. Oil will probably do it,...maybe even poly or eeepoxy resin. On the flat surfaces oil or stain will change the colors so practice on something till you get the look you want. If it's a walking surface make sure it's non-skid.
Wog has a "secret" formula for sealing wood.

I don't know about sealing but thought I'd say I lurked through your thread for a couple hours today. You sir are a self-motivated son of a gun. I thought my 17' runabout was a respectable project. Yours is a behemoth and you seem to be taking all of the challenges without missing a stride. Phew!

I probably would have reversed the direction of the original cabin (cause it would have been easier and a shortcut) but you have dramatically improved everything by doing what you're doing. I feel like all of the members here need to start chanting

Thanks! Imagine the madmen like Knotty who build the hull and all from scratch, now that's something completely different. The problem in my project is the lack of resale value, in the end it's still a -76 boat with a -87 engine. But then again I will -never- sell this one so it's a moot point.

I can imagine a 17' would be a bit faster to build, but I'd wager that the building phases are almost the same. I've always admired the loonies that gelcoat and wetsand whole hulls from start to finish. Now that's dedication and totally out of the question with this boat. I'd spend a year doing it :)

I just started following Knotty too. Both big projects!

I'm dreading doing that to my 17' runabout. There's not a power tool big enough to do yours ;)

Quality wood panel always adds that little extra in my opinion. :thumb:

Now it's time for acetone and Sikaflex. Then some Le Tonkinois on the underside and the floorboards are done!

Nice woodwork there Red. I do know a ton more about woodworking then I do fiber glassing. My shop is setup for wood working and I have build some Furniture pieces over the years. I do like the mitered corners. It sets off the project.

One round of filling the seams and sanding left, before the fitting and varnishing part. Fuzzy stuff but the results are nice.

So earlier I saw you had a sheet of marine grade veneered teak plywood. How did you end up cutting them into the boards/width, sealing them and appears like a beveled edge on ea. board. Also looks like you have a sheet of teak veneer on post 608.
They look great.

True, this all might seem a bit cryptic :)

I bought two sheets of the plywood and was happily surprised it was enough for everything I needed it for. We used old wallpaper as templates and fit them as well as we could. After cutting and sanding the pieces I added a 2mm gap with a pen and a washer, rolling the pen inside the washer along the walls around the board.

We categorized three different groups of panels: floors, doors and countertops/ceilings. The floorboards that we did first are made of 10mm teak slats bonded to plywood with Sikaflex 298 and screws in the outer bevels. Then it's time for the veneer which will be used to cover the cut edges of the plywood on the door boatds.

I'll post more pics soon!

Change of plans and a lot of varnishing. Skipped the veneer part and used thicker wood instead.

The last photo is after four coats of Tonkinois, will add some matting agent to the two final coats (coat 6 & 7).

Come to think of it, the fourth layer up there is still wet and hasn't flattened out yet.
