I would go bigger.
Ours is small because it needs to fit in our "tender garage" at the back of the boat
It's a great system, I can launch the dinghy
in less than a minute, but it does limit us to small dingy.
The small model does have the advantage my wife can pull it up on the beach on her own, with outboard
. (I tend to cruise
out of the way places and the only landing area, generally, is a beach) which would not be possible with a larger heavier model.
In all other aspects bigger is better.
I checked mine and it is a TL240. We can just get 4 in, but only if they they are not overweight and its calm conditions.
Three is its realistic limit.
