Re: Catalina wing keel or fin keel?
We have a C28 with a wing keel, which in my opinion is quite desirable here in Florida, where shallow water is everywhere. I agree with all of the above posts...the main consideration for a wing would be the depth where you sail. If you have plenty of depth and it is not a consideration, general consensus is that the fin will point higher, perhaps be a little stiffer, and be slightly lighter. The above observation is correct that wings are usually heavier to compensate for the shallower draft.
I can't comment on whether the wing is more difficult to get unstuck if grounded...but how often does one run aground?
