Hull extension

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?
 
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
 
Spare I will keep a look out. But will this be as strong as if I laid new glass for the two foot filler? Its a long shot but I will check the 18 Fisherman I have at the house. I think it does not have the deadrise ? of a V20 though.
 
If I do decide to register it home built, do I need to go thru Coast Guard? And who determines max HP? I need a 300 HP rating at least. Also what about the HIN? Does it need to disappear?
 
You probably don't wanna do home built BUT if you do it will be through your state title office... you will turn in receipts and title/hin number of parts boats used and you will be issued a new number and title.... hp rating is determined by whichever is more restrictive a formula (length beam freeboard deadrise hull style etc) from the coast guard site and by the builder (you)
 
Jason I have an old Hull Stretcher in the garage, very easy to use. I'll sell it for $500. Just MoneyPak me the money:sly:
 
its on!

Sorry I dont have the cash. I propose a trade. I will trade it for my 16 ton hydraulic nail unbender, a meglinating variable intensity multifunction power tool, 18 volt cordless hammer, and a 7 function multitool (has meat thermometer, gaydar, and a paternity test). :haha: and i might throw in a bucket of propwash too.
 
with some quick reading it looks like rated hull capacities are regulated by law on hulls UNDER 20' .... if that's true then u are clear to go ... ehem.... buck wild!

:beer: Fantastic!!!! Trade works well!!!! Hold on while I put my Bargainin Britches on........ I'll do it for the MVIMP tool(mine has a broke torque rotation awl....), hmm...I like the multitool though I own a Garden Center so I have the best Gaydar money can buy.......but the paternity test could come in handy.......the hammer would end up on Ebay. Tell you what....throw in a generator for the nailbender and we'll call it a deal!!!
 
Hmmm. You drive a hard bargain. I have a smoke and fume generator that will work but I use it to keep mosquitos away. How about a combination extension cord water hose? It would be perfect for your garden center!

Your right. And further more, the Coast Guard ratings are mostly for weight not speed. So what happens if I hang a 200 Honda on a V20? That thing weighs like a 300 2 stroke.
My goal is to have twin 2.5L Mercs. I will probably never see WOT but I will have the advantages of twins. I believe with an extension and a bracket I will get approved for 300Hp. The bracket is built into the boat so strength is not an issue.
 
Didn't read if you already have trim tabs, but if you don't - adding them will make a big, make that a HUGE difference in the ride !!!

I speculate that without tabs, making the boat longer will still require tabs to get the best ride.
