The earthrace boat was amazing for its intended design purpose I enjoyed seeing what we did of the boat on the whale wars series. But it is hard to watch the whale wars campaign. They have to be underdogs -- the "war" is one of reality tv exposure. If they were "too competent" at...

Wellcraft built other swim platforms around this time as upside-down box shapes in a mold - wood only on the transom side and a small lip for stiffness. They weighed around 100 lbs. The sides were built out as well for stiffness and looks. The hollow allowed the drive to tuck up under on some...

A few threads on inducing air / ventilating the hull http://www.boatdesign.net/forums/boat-design/use-air-14886.html http://www.boatdesign.net/forums/boat-design/air-injection-planing-hulls-21190.html http://www.boatdesign.net/forums/powerboats/air-injection-30905.html...

Yes I noticed the strake there.

I like a trailer which supports the boat as close to the transom as possible or ideally, bunks that extend slightly beyond the transom. After some years, you don't want it to develop any hook from the weight being carried by an unsupported spot some distance in front of the transom.

For completeness, no there is no shear pin on the prop. The mercruiser alpha props had a rubber hub. A "spun hub" usually allows idle speed but the more power you apply the more it slips.

NOLA is New Orleans Louisiana region ? What type of boat, how large, how fast do you want to go, and how many hours use per year?

Can you please explain this in more detail? I'm not clear how faster or slower changes how the layers would be overlapped/"interlocked" for this "24' flat bottom" (my only/limited experience with this size project is with "slower" one layer at a time.) Edit: thanks for the PM - I appreciate...

If I read this right, there is a disagreement as to whether this should/must be done in one go or not. How much strength do you lose if you use (air inhibited) poly resin and let one layer kick before applying the next layer some hours later or the following day? If it really has to be done in...

As long as it's a post 1996 year the zodiac is likely PVC; pre 1996 and it's likely Hypalon like Avon, etc. I've only repaired one zodiac where the tubes came off from both the transom and started coming off from the floor. I went with the genuine zodiac glue ( Zodiac #7097 Universal...

Why not pick up a longblock for her?

I'll take access to the backing plate side in case future repairs are needed over "automobile styled" interior any day.

Awlgrip has been recommended most to me by those who have had their powerboats done.

The catch-22 might be: you need enough volume to make it worthwhile to research and set the whole system up to mix your own resin and guarantee quality and quality control, and if you have that volume, you have the buying power to simply get it from a supplier at a much reduced rate that reduces...

Congrats! Really enjoyed both the video and the photos of your build.

I went back and searched and searched. What I found was: http://www.boatdesign.net/forums/metal-boat-building/origami-steel-yacht-construction-248-18.html#post383149 - http://www.boatdesign.net/forums/metal-boat-building/origami-steel-yacht-construction-248-20.html#post383787 - and...

Somewhere I read an article on how they do the complicated in-gelcote colors now using some kind of color inlay application in the mold. Can't find it. Anyone have experience doing elaborate designs in-mold gelcote? (I'm old fashioned - I prefer single colors ;)

If you have everything free, it should be an interesting experiment. We need more new hybrid stuff. I don't see designing the cradle for the motor's torque as a showstopper at all. Will you have a cooling system for the motors? (I'm out of my element talking electric, but am curious to see what...

I had no idea you could build a rotomold mold DIY -- I found the discussion more interesting than the original question :P But I guess we should be good and stay on your topic if you are sure you want to lounge around on some production boat instead of creating something neat yourself ;)
