Why do dinghy sailors never train?

I can only agree that you can improve in cycling much faster than in sailing - but only until you reach a certain level. Then you start to need to do a few hundred kilometres a week in cycling to get better. The top Master in our club does 600+ quality ks a week, which would take him around 17 hours or so. 

Because sailing is a mid-sized sport with lots of different classes and many of us don't train much, I used to assume that when sailors moved into other sports we may get thrashed. Interestingly, the sailors and windsurfers I know who gave up sailing and went into cycling often did much BETTER at the bigger sport.

One mid-fleet club Laser sailor returned to his old sport of cycling and has since won a bunch of state championships in his age group. A good national level windsurfer (fast enough to get places but not wins IIRC) has been national masters champ on the bike a couple of times and has an amazing ability to go from winning track racing to getting 2nd out of 600+ mountainbikers before hopping on a time trial bike and getting 2nd from 60. Another windsurfer and another Laser sailor went into cycling and did well at the MTB 24 hour worlds; a good national-level Tasar/Mirror sailor got into cycling, then triathlon and qualified for the Worlds. One world-class sailor who was cruelly robbed of an Olympic spot got 5th in the Masters worlds on the bike.

So while dinghy sailors don't tend to train that much, when we do get into a sport where you have to train a lot AND IT'S LOGISTICALLY EASIER TO TRAIN A LOT, we seem to do as well or better than we do in sailing. That seems to me to say that our comparative lack of training is not because we are lazy, but because it's harder to go out and train on a boat and also that it's a sport where thinking is much more important than in some other sports.
