20 Bertram bahia mar/ 24 rampage
Hello all, first time poster here but long time reader. I purchased a 1966 Bertram Bahia mar 20 a few months ago and have been in the process of tearing it down to the hull and doing a mostly complete rebuild on her. so far I have pretty much all of the deck, stringers and bulkheads. Now i just have to finish cleaning up old tabbing, engine mount blocks and center stringer. After that I will be getting the hull ready to add a couple more layers of 1708 to help stiffen up the hull. I am still trying to figure out posting the photos as it keeps telling me the file is too large for the server to process so if anyone has any info on how to change that it would be much appreciated. Posting from an iMac if that helps at all. Thanks in advance and tight lines.

Ok so my girl friend figured out my photo problem and here is what I have so far. Seems as though the previous owner put a new deck on top of the old one with 2x4 and 3/4 plywood. So far I have weighed 800 lbs of material removed.

Not from what he said but definitely possible to have had a buddy who helped that could have been. Definitely an interesting way to raise the deck though. Very heavy

I have seen this show a couple of times. A couple of quick notes for you. The foam was structural so unless you put it back you will have to add stringers. The original deck drains were low so you will need to raise them unless you are going with an outboard. That leads to the next note, which engine are you going with? And while you are tearing it apart check the transom. Originally they were balsa core. Good luck.

previous owner had already raised the drains when they raised the deck the first time. still debating on what engine I'm going with but I might consider a 5.7 350 as the previous owner also had one in. but that decision will be made when the time comes. and so far the transom has passed every test but ill wait and see when my moisture meter comes in. and I will be adding more stringers into the grid system for extra support. rather have that then possibly having all that wet heavy foam in there again.

Might as well consider a 383 stroker if you go gas,better power and just as good or better on fuel in the same 350 block.Also more torque and power at lower RPMs and probably your most economical powerplant budget wise too.
That would look badass with a pilothouse similar to the one farallon used to make for the skipjacks,it looks sleek without that rear facing windshield.
Keep posting pictures,we need some boat builds to get us through winter!

Yes I am still open to ideas with what power I am going to put into it. I plan on repowering my 24 rampage in the spring and was thinking of rebuilding the 350 block I would be taking out of it. I have a couple of ideas for a pilot house that I'm sure purists will absolutely hate lol. To each there own.
