What material for rebuild ?

[Blueline93]

Well I’ve finally stsrted my rebuild it’s not on a 222 but on a 246 but I see more activity in here and I need some help. What’s the best material to use for floor cap and bulkheads. I originally wanted to use coosa but the price of the stuff is insane. What’s a good alternative that I can use for this stuff, the floor is my biggest concern cause I’m going to be adding a tower as well the transom knees and bulkheads just because the structural side of it ? Any help would be appreciated and I’ll get some pictures posted once I get more done .

I'm going to move this into the Discussion forum since it's a generic question. When you start the rebuild thread we'd prefer you add it to the 246 forum.

Pictures would be helpful but some other materials can be used if used appropriately. There are honeycomb sheet boards that are about 1/2 the cost and still rott resistance along with high density foam boards. Finding a good local supplier is going to be helpful to get you through the build but most all of us that are around the board will gladly help. The laminate schedule can always be bulked up to compensate for a lower strength or dense material but your going to want coosa core where you mount a ttop or tower for its much higher compressive strength to that of honeycomb or foam boards.

agree w the above about mixing the different types of cores. I used plascore for my deck, placed on top of the stringers in most places on my build. But where the console, seat, etc. needed to be attached I glassed 1" thick 26lb coosa to the top of the stringers for screw retention. If I was going with a T Top or tower it'd be even beefier with the ability to use a toggle nut or backing plate with a bolt & nut setup. Imagine the stresses on a big top going down the highway at 70mph.

Where are you located?
I used plascore (honeycomb) for the decking with a couple layers of 1708 on both sides to stiffen it up. Plascore also makes high density foam board. When using plascore honeycomb there is really nothing to hold a screw once you penetrate the 1708 though. It's good for decking but if you to attach a leaning post or t-top you would have to embed some high density coring before the 1708, like coosa or hardwood or even resin soaked plywood (not a great choice).  You can go to a marine surplus place and they usually buy scraps of coosa from builders. That would be your best bet.
Are you re-doing your transom? If so, what are you using for a core?

I’m back and fourth on redoing the transom it was redone in 2015 before I got the boat they used marine plywood and what looks like epoxy. I know realistically it will probably last for a good while but we’ll see I’ll have to get some pictures of everything once I get it more torn down

What model boat do you have?

If you want to post a pic when you talk about your boat, which you should, follow the instructions here http://classicaquasport.com/smf/index.php?topic=12725.0  - don't attach them - you are limited by file size. Uploading them into your "member gallery" is better for viewing.
Spend a few minutes to absorb the instructions. It's really easy. Remember if using a phone to take pics, to hold the phone horizontal with the lens to the left.

I’m actually right in ruskin right outside of Tampa too

In that case, you might want to contact Fiberglass Discount store. I haven't purchased materials yet from them but their pricing seems to be the best and the service that Jesus has provided thus far has been great! FGCI is also a resource in that area. Hope that helps.
