I am starting a rebuild of a 1972 Repco30 lobster boat. As you can see from the photo, I am working with a blank slate more or less. Old boat had an inboard, I am converting to an outboard.
I am open to NON wood alternatives (coosa, divinycell, plasticore, etc etc) and will use some in the rebuild. I am trying to balance cost vs performance in the cores I pick...as you all know, those cores can add up quick. Using GP polyester resin throughout the rebuilt.
So, with that in mind, couple questions:
Stringers - current ones look ok, I am going to seal the holes and reglass. I will cut out the bad sections midship foward and replace. As well as add 2 more. Thinking COOSA or WOOD here... coosa just so darn expensive. Thoughts? If wood, what kind - some kind of hardwood?
Bulkheads - PLY or FOAM. Maybe a lower cost foam core (Carbon Core makes a reasonably priced PU) or marine ply.
Gunwale - PLY, FOAM or HONEYCOMB - I am going to raise the gunwale, which makes me think a good foam (on edge) would get me the 6" or so raised wall, then create a "box" and glass the whole thing.
Deck Support - GRID SYSTEM or PULTRUDED SUPPORTS - In the shallow areas of the hull, I will rest the deck on the bulkheads and stringers. On the deeper parts, I will either continue the stringer and bulkheads UP to meet the deck, OR use pultruded fiberglass square tubing to support cross members (also of pultruded fiberglass tubing).
Deck - HONEYCOMB, COOSA or PLY - I like the idea of spending a little money on the honeycomb vs the ply...mainly to save weight.
Transom - COOSA or similar. I need to reinforce transome to carry the outboard...plan is to make it 2" thick min, buy building up 1/2" coosa and glassing. 1/2" so I can follow the crown in the transome, bend / glue / laminate repeat.
I am open to whatever advise you all want to throw my way - on material selection, build suggestions, and CORE SUPPLIERS that won't break the bank. I am in Massachusetts.
Thanks
