Re: Aloha 34
I don't think that it matters very much if it is keel or deck-stepped - the mast is much too big to make it convenient for dropping to go under bridges. If this is an absolute must you need to look at boats with purpose-built tabernacles. I think there are some Dutch boats like that.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
