Our Finn pals can get pretty crafty when it comes to moving their boats (a fully rigged Finn is just over 300 lbs), so when I saw this double trailer rig, where you can singlehandedly load/unload the upper boat, I thought it might be worthwhile for people here to take a look.
For a boat the weight of a Finn, yes a very slick rig. But for a Laser that is around half the weight (and a flat deck), seems like stacking them would just be much easier.
Seen a few people using similar for lasers but its overkill really (for a Finn I can quite understand though). Two people can easily get a laser on top of a double stack and if you really don't feel strong enough its usually easy enough to grab someone else in the boat park to help.
