Re: Hull Extensions for Catamaran

It's been interesting reading through this thread again. I wonder if Southern Star ever did his hull extensions, or did he get so much "good advice" he abandoned the idea?

Re: Hull Extensions for Catamaran

Dunno if you can get it in the US, but Australian Multihull World has an article about a guy who extended the transoms on a Seawind 850.

Doesn't go into a lot of detail, but he did a very nice...

Re: Hull Extensions for Catamaran

For me the biggest concern would be the fact your boat has 16 year old gelcoat....

Re: Hull Extensions for Catamaran

Getting back to the actual topic, a few questions: how long do you intend to make the extensions, how deeply submerged are the current transoms, and what beam are they?

Re: Hull Extensions for Catamaran

Well OBVIOUSLY, before you start work on the boat, you need to build the multimillion dollar environmentally controlled work area....

Re: Hull Extensions for Catamaran

Re: Hull Extensions for Catamaran
