I remember that the dinghy sailors had completely different gear than you would see on a cruiser/racer. We wore "sailor john" suspender style light weight wetsuit with a neoprene collared jacket to keep the water from running down your neck.
If it was warm, we would just wear the jacket.
I did a return trip from Bermuda to Ct a couple of years ago. We were taking a lot of spray and some green water, no dodger as it is a race boat.
There were seven of us with everyone wearing something different.
There was one guy wearing the best of the best of everything. It didn't seem to matter much in those particular conditions.
If you buttoned up enough to keep dry you would sweat.
We all would open our collar a bit to get a little air. Just then a big wave would wash over the boat hit your chin and fill up your shorts.
By the time is started to dry out a little it would happen again.
We were sitting in an inch or two of water a good portion of the time. Nobody was dry. Some outfits cost thousands some a couple hundred. We were all wet and miserable all the time.
