Thank you, very informative, I take that it is then not a good idea to use epoxy to fix damages on a WEST system hull!



NO! Epoxy is the ONLY thing you should ever use on timber. Polyester and Vinylester will NOT stick as well to timber as what epoxy does. As stated above post

1. W.E.S.T. is an accronym that stands for Wood Epoxy Saturation Techinque. That alone should tell you that you should ONLY use epoxy resins when using wood.

Brunzeel cedar ply certainly rots.

I know about those, being a sufferer myself.

Any and all timbers will rot given the right circumstances, some just take longer to do so.

So how would you rank the following hulls?

Marine ply

Cedar WEST strip

Epoxy with foam core

Epoxy with balsa core

Epoxy fiberglass

I would rate marine ply the lowest!

Cedar epoxy strip plank.
Epoxy foam core [as long as its solid below water line]
Marine ply sheaved with epoxy from new.
Solid epoxy/glass
Balsa core a distant last. Balsa above the waterline maybe but absorbs too much resin.

I have seen some beautiful hulls built out of marine ply, I certainly would not discount it as a building material. It's more a matter of horses for courses, small boats built from ply are more likely to be day sailers or maybe coastal cruisers if the conditions are light.

Again thank you guys for the knowledge passed! I have been looking at a few sport yachts (Ross 780 Atkinson 26....) all with WEST cedar strip hulls now I have a clear view and will not dismiss that kind of construction!

the 2nd one looks good shame it is a fixed keel.................... need to make a jinker but would need a deep ramp to launch!

I would have a cedar core hull before I would go with foam cored hull.
