Its Kind of loaded funny question. It seems that the people who only get to the boat 50 days a year actually sail 50 days a year. I think the question should be how many days do we get underway. I'm mostly a full time cruiser. I leave the boat for cycling trips and passing out at festivals, what have you. It's march and I've "checked in" six times. My average sail is a bit over 100 miles.. With an occasional race that only gives me about 10 days of sailing so far. I would likely get out more if all that oil in the bilge would finally grow a motor.

I didn't read all the replies, and it was probably mentioned, but some of us live where there is only a 4-5 month season...

Even getting out on the boat every weekend, all weekend, is still less than 50 days a year...

I usually get 4-5 months too, but this year I think it's going to be a bit less. This is how my boat looks today. We're in the middle of our second late winter blizzard in 4 days. Almost three feet fell just today.
This **** won't be gone until August lol.

True dat, I had to think about how many days I actually get out. I am good for about once or twice a weekend, and 2-3 times a week, actually sailing... Some of those sails are 2-3 hours, some are all day long. But I can't put in the water until the first week of May, and must be out by the 2nd week of October. The rest of my time is wasted here, waiting for the lake to go liquid again.

roughly 5 of every 7 days so far, but then I just got her and most of those days are repair / maintenance / just plain work while on the trailer

Not enough but we will be full time cruising next year.

Roughly 10-15 days,

Not enough!
