The more I watch your work, the more I realize I don't know. That beast is going to be awesome.
Hahaha!! She is certainly one rare exception!! I damn sure don't know it all. Keep learning everyday! Thanks for watching!! I appreciate your comments! This editing is a challenge!!
Fantastic job Just like Bertram👍
Beautiful work, u sir are a true Professional.
The transformation is quite rewarding! And the people involved are awesome people to work with!! Thanks for watching and I appreciate the kind words!
Continued beautifully detailed work! I’d love to have a boat built with that level of quality.
Thank you, Chris!! It certainly is challenging!! Thanks for watching and sharing your thoughts!!!
I Love these videos, almost as much as I love 31s.
I am very happy you like them!! They are... a challenge for me to produce!! 🤣
I was just looking at you website and saw my canal. My homeowners park is directly adjacent to the Billfish 39. I look at that boat every time I leave on my skiff, a 16' Billy Knowles.
Billy Knowles was a great influence early in my career. I believe he said, "Fiberglass can make any shape in the World. Why make it flat?!" He may have been quoting Rybovich. What he was getting at was how subtle curves can add to the aesthetics of any part of a boat. I was involved with the development of the Billfish 39. Hull #1, the only walk around was my work. That is about all I have to say on that topic.
@@vernesecustoms John was a big influence on my career (billfish biologist) path. Jan Fogt introduced me to him in 1986 or so. I met with Knowles a few times when I was thinking of getting a flats skiff built. By the time I had funds enough he was out of it and I got a Paradise version based on his design. It will beat the living crap out of itself and you in the process but it sure floats shallow.
Time for bed. Take Care
As far as offset rudders, In the world of tournament inboards (ski, wake, and surf boats), some manufacturers offset their rudders. The main reason for a rudder offset is to be able to remove a shaft without removing the rudder. There is not really any hydrodynamic benefit with an offset rudder. I have been with correct craft (Nautique) since 1991. Nautique rudders used to be airplane wing shaped (you had one curved side, and one flat side). They were shaped that way so you could counteract propwash, and essentially "tune" the rudder to the boat. You could have the steering pull left, right, or neutral by sharpening, or flattening the rudders trailing edge. In the same way you would have lift for an airplane wing by changing the way air flows over the wing, you can now have torque for a rudder by changing the way water flows over the rudder.
anyway, great videos, I just purchased a 31, and am about to dig into it for refurbish. I enjoy watching your videos for a bit of education
Very cool! Great info!! Interesting, the wing profile.. glad you enjoy the videos!
Great work ! I am not from the US so don,t know anything about bertram boats. Is it economical doing a massive amount of work like this or is it a labour of love by the owner.
Keep up the good work and grtz from Holland
This boat would fall under the "labor of love" category. Or some grey area near that. Not economical. These old Bertrams will be "redone" to some degree many times over. Thanks for Subscribing and the kind words!! 👍
Awesome build!! - Any idea what the approx “budget” for a build like This needs to be?
Thank you for watching!! I have I rough idea... vernese.com/contact/

What does the surge tube/pipe actually do? Are the struts aluminum or stainless?
The surge tube is a fail safe just in case water were to fill the entire exhaust system while the engine was not running. (Anchored and boat sloshing) this chamber creates one last effort to keep water from backing up into the turbo. The Struts are stainless steel. Not certain the alloy. Very heavy duty for 300 hp!! Great questions!!👍
I have heard some talk of building tunnels for the wheels so that you can spin bigger, newer styled wheels. Has that fallen out of favor or were lessons learned that it wasn't worth it?
Interesting you should ask! I have designed a set of Prop Pockets that have reduced shaft angles to 5° increased Propellor Efficiency upto 96%. We ruled it out for this boat because the recently replaced fule tank would be scrapped and several other major modifications would be necessary. I certainly would like to rebuild a 31 with my design... maybe one day.
@@vernesecustoms I wish I had the coin to do so. Did they expand the fuel capacity with the recent replacement? I had a 1973 31 when I was in high school in Stuart "Nakota". Well, my family had it but I was the main user of it. All of my beer money from mating went into that boat. Is there an ability to change the fuel tank configuration? Maybe a T shape?
@DerkeFish it certainly can be done. Not on this boat. I would find a bare hull if I were to give it a shot.. certain it would be a drastic improvement over the 15° shaft angle that left the factory.
How much lighter is Coosa than plywood? What is the objective of having the exhaust thru-hulls where they are. They seem to be pretty low in regards to the waterline.
Coosa is available in different densities. We use Bluewater 26# for the stringers and 15# for everything else you see. I heard once that Marine Plywood is 26# density. The exhaust system is as high as we could manage while keeping it below the cockpit sole (deck). They will be mostly under water with a heavy load or ready to fish. The only other option would be dry stacks.. 🤣
@@vernesecustoms I saw an image of a refit with side/corner exhaust thru-hulls. What would that benefit be? Just cosmetic? How about oval thru-hulls to snaz it it a bit?
@DerkeFish we discussed both options! The owner preferred the traditional transom output. I have done side exhausts with great results. If done correctly, NO backpressure and the wash carries fumes away from the boat, eliminating the "station wagon effect"
