I currently use a large trailer from my Macgregor 22 to transport my wife's sunfish, but that trailer is large and heavy. This summer the boat will stay at the lake in dry dock, so it would be nice to just roll it to the water by hand. Since my wife and my younger son will be doing this by themselves it needs to be on the lighter side. I am between a full size dolly that goes all the way to the front of the boat like the one intensity sails sells and a boat trailer from harbor freight which is small as it only goes to the wheels. they are about the same price. I am leaning to the trailer, but how heavy is that trailer? The negatives of the dolly seem to me that they might be a bit flimsy, keep in mind the boat will live on the dolly while not in the water, also I am not so sure how secure the boat is on the dolly , again my younger son or wife will be pulling it, up and down a boat ramp.
