up is faster but down is much safer
have cat 25 swing keel. I had thought better to bring up when sailing downwind to reduce drag however in reading sounds like better down. could someone explain?
Its true you can go faster downwind if you drag less stuff in the water.
But not much faster.
Here's some problems and why I leave mine down or close to down all the time.
#1 if your cable breaks and keel falls, you may sink, right now, right there.
#2 you "will" forget its up, and when the wind or your course changes, so will your mood.
I learned my lesson when rounding a headland and changing course only to find myself being blown toward shore, it took awhile to figure out why the boat wouldn't work. When heeled way over the keel jams and you can't get it down. If you unwind the cable even a little not knowing the keel is jammed it will fall when you finally reduce heel and then see #1 for possible result. When things go bad, they happen fast and all at once. "Don't set yourself up". (how many times have we said that) duck, ouch
#3 "the biggie" if you run aground with the keel up going downwind your stuck hard and maybe stuck the rudder too. The good news is you can get off and walk around the boat looking for a good place to shove.
