Glastron CVX20 Project

[tnelsmn]

Check out Ron's build on his Glastron. He added a pad and runs it with a 2.5 Merc. Page two outlines how he added the pad.

And another picture of a pad hull.

Cool project you have going. Here is the pad I added to a 17' V, it might help you. Dead flat raised pad as opposed to a delta pad approach.

And here is the pad on another boat I have a 23 footer. In my opinion, if your hull is going to be multi-use and your glass man is masterful, I'd strongly suggest you add a couple of degrees of deadrise in any raised pad you settle on to make it a bit more forgiving.

Wow, great great replies, thanks a million. I have a pretty good idea of how to solve this pad.

Question two: The 27 gallon fuel tank was located up front under the deck and I'm sure that's great for skiing, but not sure if its good for stability at high speed. 27 gallon is far from enough for a Monty motor and I am playing with the idea of using two tanks in the rear instead. Opinions?

Cool project !
I'm doing a structural restoration on a 21 Checkmate Starflite that may get one of my V8s so I'm looking at many of the same issues.
I'm leaning towards a supplemental belly tank that would be used when the extra range is needed (which might be most of the time lol). I plan to have a small transfer pump to fill the main tank from the belly tank. I don't mind losing my in-floor ski locker, not sure if the CVX-20 had one or not.

Thank you Sir!. The fuel tank issues has been solved if I can get the welder to do it. Two saddle tanks in the back with a 4" pipe welded in between them will fulfill the requirement of the coastguard. The knees that I am putting in made out of coosa will prevent any other option, but I think the pipe will do. I will then move 3 34 size batteries up to the front and we should be all good weight wise. I have decided to make the pad 16" wide, and 7' long. It should give the boat the ability to run with the best as well as continuing to be a nice ski boat with the keel it has forward.
