strip planking v ply

a couple questions

can strip planking be done cheaper and of the same quality as ply?

can a design for ply be strip planked without major changes other than subbing strip for ply?

will it require more frames?

 

Yes and no to all above..
I'm afraid you got to be more specific if you wan't more accurate answers..

 

with comparable boats can strip be of just as high a quality and cheaper as marine ply isn't used?

how would the structure differ between ply and strip, other than the hull plating?

this would be at or under 40' x 8.5'

it's a displacement hull and speeds

 

At that size defineatly strip planked IMHO

 

you're saying you prefer strip plank at that size?

 

does strip planking require closer framing?

 

Yes, because you lose the benefit of the bracing provided by internal cross grain transversely extending across the hull.

 

see, you can say things i can agree with

would being epoxied make up for some of that?

 

And not at all if you use the internal stucture to carry the transversal loads.

 

Yes. Epoxy would add strength. To what extent? That is a matter of skill.

 

I'm thinking bead and cove over frame waterproof glue with glass epoxy covering

what kind of glue and other thoughts?

 

Of course, you are right. But lacking that it would be weaker.

 

That's better with smaller boats, boats treated with conventional impregs and glues, not worth a though if you were to use epoxy with glass..

It's a very broad subject, and there's no single right answer. You need some reading like Meade Gougeon: The Gougeon brothers of boat construction..

 

can you elaborate?

 

It's a more complicated matter. Think of every bulkhead, cabinetry and shelves as a part of internal framing. Everything is arrangenge so that the "panel size" around the boat is in right proportions and sufficient to support the hull skin. In this so called "monocoque" structure it's all glued and bonded together, covered with directional fibers and epoxied together. No screws or nails needed. Anyway it's a good structure and no more vulnerable compared to any framed boat which can also be just as good as the engineering behind it..
