Hull extension

[jasoncooperpcola]

Has a hull extension been done on a V20 before? How would adding three feet affect the handling? Opinions?

Jason, this isn't on of our V's BUT this is an EPIC thread.... GOBS AND GOBS of knowledge here..... Get a COMFY chair and a few sodas and settle in for a LOOOOONG night or several nights.

I just read the first page and learned a ton! I would only add two feet if I did do it. 22 is a lucky number for me, my bday is on the 22nd of July. Thanks for the link Smoke, I am going to spend some time and read it. Just based on rough guessing a two foot hull extension would add around 500lbs of flotation. This is really alot to think on. Lots of modification but I cannot think of a better time or better hull to modify.

a friend of mine that used to make glass work boats(Diamond Boats) would stretch hulls all the time, he had the mold for the 27 Aquasport and would make a 30 out of it with no problem, he had the mold so it was easier for him, but on ones that he didn't have the mold, he would use the back 4 feet of the hull as the plug, make a mold off of it, use the mold to make the extension and section it in.

I saw Dale Earnhardt Sr.'s boat at Palmer Johnson having the 30 feet added to it, he had to make his bigger than Rusty Wallace's

Wow...that's something I've always wanted to do w/a V20...and while underway, beef it up enough to handle 250 HP....I hope you'll do this and post pics along the way and when finished...wet tests and all...my vote?...GO FOR IT...if I lived closer, I'd come help free!

Just a thought...these boats, to me have forever seemed butt-heavy...occurred to me, you might wanna leave the fuel tank in the front as you extent aft to help offset some of the weight on the stern...especially if yer gonna go up in HP...

Thanks for the encouragement Smoke, Spare, and Reel. It seems building the mold and getting it lined up is the hardest part. If I do the hull extension I will still do the outrigger bracket which takes some stress of the extension. Good thinking on the fuel tank, Reel. Do yall think additional stringers may be needed? Such a modification will have to be done using epoxy for the most strength. I will need help though. Another question, is regarding title. Will I have a 2013 Wellcraft V22?

[smokeonthewater]

only if you decide to title it as home built... then it would be a 2013 or 2014 JCPF v22

Stringer would have to be extended to tie in with the transom, you can sister them in place to the existing stringers. Epoxy is good, but not neccesary

She is getting new stringers so that is covered. I plan to use epoxy on the extension and bracket just for my own piece of mind. Still undecided on the extension. At this point I do not care how long it takes I just want to do it right. The hull bottom is 3/8 - 1/2" thick right at where the cuddy starts. Is it the same all the way?

you know, the easiest way would be to find a stripped out derelict v20 hull and graft the two together, look around, you could probably fine one. Check with Lanier Marine Salvage. If you find an I/O boat to cut the back off, it would be an easy bracket job from there
