Re: GV11 weight

Hi, Just saw this. The 120 lbs is assuming lighter weight okume, not fir. Adding 6 oz on both sides, bottom and sides?? If you are going to use it as a fast planing hull and go fast, a single layer of biaxial glass, inside and out, on just the bottom panel is recommended. To prevent checking in fir ...

Re: Mattkab's GV13 questions

Yes, but I'd also add an extra layer of tabbing there.

Re: Mattkab's GV13 questions

Thanks for asking.

I'd suggest two points:

- aft frame that supports the bow deck down low (single point) - should clear the fwd seat.
- or at the sides forward where the bow deck meets the hull (2 points)

Re: HELP!! Anybody got a tip on removing rubber cement

Maybe citristrip? Rubber cement IS tough. Mechanical removal might be easier.

Re: GV 11 materials question

And take your stir stick and cut a sharp edge to it. You don't want a rounded corner in the corner of a mixing cup. Use the good scissors; your wife won't mind.

Re: Mattkab's GV13 questions

Hi,

For structural reasons only the 2 bottom panels needs to be covered with biaxial. No need for the light cloth on top of it for structural reasons. It's not needed on the sides except for added durability or to prevent checking if you used marine fir plywood

And yes, that's the correct sequence.

Re: Foam dinghy

The problem with ultralight foam/glass dinghies is the skin is pretty vulnerable to punctures when you drag it up on rocks etc. 12 oz is as light as I would go - and maybe an extra layer along the keel line if it is a V bottom. Those sort of davit holders are Weaver - look at pg 13 and 17 for detail...

Re: Plyak 12 plan question (new boatbuilder)

The vertical dimensions are spaced 24" apart horizontally. (look at the top view above where it says '24" typ.') 1) So the 76-3/4 is the distance from the right hand (?) mark to the very end of the panel. (I.e. 4-3/4" past the 3 x 24" tick marks = 72") 2) 12-5/8" is the vertical distance from the ti...

Re: Kevlar vs fiberglass

Carbon does not float - it has a higher density than typical resins. Kevlar is quite light and will literally float in a thin layer of resin, so vacuum bagging is essential to squeeze it down. It just fuzzes when sanded. It's not impossible to repair, but it is trickier. Kevlar is very strong in ten...

Re: GV 11 materials question

It's not that big a deal to glass after the frames are installed. You can glass the bottom before the transom knees are installed so it's only really 3 panels. Certainly it's a LOT less work than creating basket molds or exterior framing. No, there is no strength difference. The hull is locally stro...
