Re: Full or fin keel?

I can't believe this went on for 50 pages.

Apples, oranges - which is better?

I love the technical discussions, the opinions I take with a grain of salt (and then a shot of tequila).
Here's my opinion -
On my Gemini (catamaran) with the boards up it was akin to a long shoal keel - 32 feet long, but only 18 inches deep - and it sucked to leeward, I mean drifted. Board down and it was 5/12 feet of asymmetrical lifting pointy-ness.

On the Irwin 38 Mk II I have the shoal keel, 4.5 feet of stubby. I don't care about the extra 2 degrees of leeward drift in 5 knots of wind - because I'm probably going to be motoring in 5 knots
Once the boat gets to speed it points just fine.
I don't care about the 3-5 degrees of extra point I might get out of a fin keel (6 foot, optional on the boat) - because I'm not racing for the buoy.

I might care about the extra degrees on a 500 mile off shore leg but only because it will save me a half day on the trip. Then again so will being able to cross that sand bar without dragging or bouncing off the coral.

Lessons learned are opportunities earned.
