There is no core in the hull. Just glass. Wrapping up a ground up restoration on my 20 Moppie this week or next.
Go for 10 on the beam. I know you’re worried about trailerable width but unless you’re trailering past highway patrol regularly, it won’t be an...
Thank you
Hello, In regards to hull design I know that a lot of attention gets paid to deadrise angles, chine width, beam, etc. but I’m hoping that those...
The weight of the structure is a concern for the overall design/performance of the boat. The three adult males is a reference for a strength...
Hi guys, Im hoping to get some info in regards to carbon fiber and what weight of materials are needed to create a stable standing platform....
The Bertram 20 I have is most likely going to be put back together as OB, mainly because I already have the engine and bracket and don’t have...
Very true. An older formula I was looking at last year was so tight you couldn’t fit a finger between the exhaust manifolds. Thanks for the help.
Amazed to have gotten more direct information from TheHullTruth before this forum but regardless, someone on THT provided some very useful info...

So to be sure there’s no mistakes, I could in theory run a vacuum line from the breather outlet up to the gunnels or somewhere high for security?
Hi guys, I’m sure some of you know the answer to this so I’m hoping you can help me. Is it possible, or reasonable to run have multiple fuel...
Hi guys, I’ve read a lot about finishing over epoxy with a urethane to protect from UV but if I’m painting the hull, should I apply paint to the...
What is the consensus on these? I’ve heard no more than a 5* angle and around 3 inches but who knows if that’s true. My last boat had chines...
So I was ballparking a bit. 3/4” is 68.1lbs a sheet and 5/8” is 56.6lbs a sheet. Spira’s larger plans call for around 7 sheets for the Hull...
Lol no not in that boat. Just hypothetically. Assuming a boat that’s not a flat bottom. Thinner ply is easier to work with and likely saves...
