Having run my V21 through tight 4'- 5' waves, I wouldn't want to do it for say 25 - 50 miles, plus larger wave swells too.

The boat ran fine, for what it is, and with the tabs, I wasn't pounding either.

I just don't look at the V's as a serious offshore rig - more of an inshore to about 25 miles out rig. It is what it is, roomy, nice riding, great looking.

That said - hey, go for it - take it way off deep and catch lots of big fish.

For serious offshore, I'd prefer to be running a 28' Henriques, Carolina, Bertram, Albi, etc type boat. Built for it.

I have had my share of rough trips in on the V. And I have never felt uncomfortable during any of those times. My main goal with the hull extension is more cockpit, and more flotation. I would run a V20 to the rigs if I had a motor I would trust and a kicker. Or twins. I do not want to go big because then it becomes a pain in the *** to run it. I have the feeling I will be going out alone alot so I need to keep things manageable. 22-24' with twins would be at the limit for me singlehanded. Not to mention I am hoping if I can gethe weight ratio right that twin 200 Mercs will be easy on fuel. I think it will cruise at 30-35 with the twins turning 2000? I am going off what I have seen here. Its gonna be a way different boat when done.

30-35mph @ 2000 sounds really optimistic but potentialy awesome as well.......

I am going off reports of 45mph with a 200 Merc. So twins is 90mph. SCARY! So I am figuring half throttle would be 45mph. It will probably be lower. But I expect no less than 70mph and I hope I never max it out lol.

Haha....Well best of luck sir and HANG ON!!!!

Yeh well, the 96' V21 supposedly holds 70 gallons so 200 miles is about the range.
Unless maybe with a 140 hp honda 4 stroke, then figure 250 + miles.

The fuel burn numbers will be interesting. I remember the 250 Sport with twin 150 Yamahas was not a gas pig at all.

If you add 5' to that hull off the rear that will be one hard-pounding ****ty ride. Look under the boat and midway there is a big wide flat spot where the fuel tank rests that stays in the water at cruise. Adding five feet shifts the weight further back making that flat spot your point of entry into waves in a chop. That will beat your fillings out

Also regarding power, the boat is not made for that type of power without major modifications. Go to a boat dealership and ask to see the hull core samples of these modern 25's with twins and you'll see about 3/4" to 1-1/4" thick fiberglass layups. Our boats have nowhere near that, ours are more like 3/8".

Not trying to be a downer but because it was done before doesn't make it a good idea.

Thats funny Tartuffe, I was looking at the hull today thinking its going to look odd having so much "pad" and not enough bow. You got a very good point. I just do not know if 2' extension is worth all the work. My main goal is to make room for an enclosed center console with the shortened cuddy. But then again back to alot of pad with little bow. I understand what your saying and until I looked at it today it did not occur to be a problem. Twins would be nice, but I can almost buy a new kicker 25hp for the cost of another 2.5L Merc.

when i converted my i/o to outboard i would say the transom was 1/2 glass, in 1975, but i am sure its not heavy enough for twins that size. i wasn't even sure it was for a 175 and added enforcement inside when i added the bracket.

this is 1/2 x 3" steel
