I used to run a 440 which was basically a 390 with a factory cockpit, but I can't imagine that doing it after market would be worth the expense and risk.
years ago extensions used to be done, when boats were build more heavily. on a Carver? I woudn't try it and i doubt you'll find a reputable yard willing to take a chance, the hull aren't strong enough to withstand the stresses.
There is actually a 1993 440 Motoryacht with an extension on it for sale on yachtworld. I believe its now listed at a 50, 51 or 52. That is the same basic boat as your 4207.
This is a nice setup and you can put a extended swim platform on it. It should be alot cheaper instead of redesign your yacht
? why do you think older Carver hulls are weak ? And I do agree that I would put an ext. on any newer boats. But adding one to a 36/4207 would be costly and not worth it IMHO
Probably this: Boat Review by David Pasoe - Carver 370 There's a reason you get so much boat for your money. Doesn't mean your Carver is not a nice boat or you can't get years of enjoyment from it. It does mean you should probably avoid rough water and not even consider serious passage making. It also means structural modifications may not be possible. ps That article is old and I have no idea if all Carvers are underbuilt the same way as the boats he looked at.
well I see that you found what was wrote about the 370, now for the other half, Carver spent a lot of money buying back bad hulls and O don't believe everything you read. They found out what went wrong and fix it. Now that being said I'd think there's darn few NEW boats out there with enough glass on their sides to go adding 4 or 5 foot to them. The boat owner was asking about a 07 class boat which is older and thicker than the 0 class.....so please don't put all Carvers in the same class as one failed batch...that the company stood behind...
Once again, somebody who doesn't own one chiming in on a review that didn't have a lot of research behind it. I own a 1994 Carver 370 that I have owned since new.... The boat just like the one in the article. We also have a few of them around my marina. In 1997 when Carver first realized they had a problem with a few boats they immediately called all owners and took the boats back to the factory on their dime to repair and then improve them. No problems since and I have been in some pretty rough / steep / tall Lake Michigan chop/slop with the boat. No problems and I am a happy owner. The extension can be done, as noted above. Plus the 390/400/404 is the same boat as the 33/350/355/356 with a cockpit added. Same goes for the 38/430 CPMY, the 396/444, the 455/456/500/504, and the 506/564.
great rebuttal ! It gets old seeing that review ....maybe David should update his site one of these days with the whole story .... And ext. were done on the 3607, they just did a few and added a 4' cockpit to them. It looks real nice. And as far as sea keeping I've had my 3607 in 6 footers on the Chesapeake Bay and yes following and quartering seas work me over on the helm and gas but that's what being the Captain is all about...and I'll trust my Carver to get us back...
I'll gladly welcome first hand experience and advice from owners, but not one surveyor who did one boat in the late 1990's. Especially funny when somebody hears from their brothers friends dockmate who knows a friend who heard a surveyor say something about a lesser brand boat besides a Hatteras, Viking, or Bertram whos friend knows somebody who had one 20 years ago that had a problem with it. I would rather be on a Carver than standing on the shore watching somebody else use their boat.
speaking of a couple of those boats isn't there a tread on this site, where the some of those high dollar sport-fishers had hulls that came apart ? Never heard of a Carver bumping a buoy and going down because the hull split and never seen a video or a photos of one coming in to port with her sides flapping like a gull.....
