Centreboard Trismus type vs fixed keel architecture

Re: Centreboard Trismus type vs fixed keel architecture
Hi
I have been the happy owner the last year of a Triswood 35. At a mooring its swingkeel has been pushed up by a big coral and sailing upwind became allmost impossible. I succeeded to pull the centre board back down by attaching it to a wreck under my boat and wait for the flood. The keel is impossible to pull back up by the winch, but now she sails nice upwind again...

Some very interesting stuff on here about the boats, thanks.

Matt, hopefully you find a good solution to the inside of the case. I guess this and Vortecs stories highlight the downsides of centreboards and the added complexity and maintenance. But then I remember seeing how easy it was to dry out a lift keeler to do underwater work that in other ways makes up for this.

Cook did his voyage between 1768 & 1771... Also, when I try to google "poms" the only answer was an Amazon necklace with a monohull on it ? Make me less ignorant: What are your "poms" ??? Thanks

Pom = Aussie slang for a person from england.
