Wing, fin, or bulb...what are the trade offs?
This topic also was covered about a month ago in the General Discussion category. I suggest taking a look at those posts, so I won''t repeat all that I said back then. Suffice it to say I''ve sailed wing keeled boats since 1989 (first a Pearson 27 and now a Pearson 33.) Yes, they are a compromise and won''t point as high as a deep fin -- although I am quite impressed with the windward ability of my P-33.
But you can''t beat the shoal draft of a wing if that is what you''re after. You won''t go aground much, if at all, because the shoal draft will let you go places other sailors can''t. I''ve touched bottom exactly twice in all these years and I''ve sailed the width and breadth of the Chesapeake, the home of skinny water.
I have no experience with a Catalina wing but it sounds like you have. Go for it.
