I have two related problems: (1) what kind of trailer would be
suitable for short (15-20 mins, around 45-50mph) hauls - accomodating
a wing keel on an S2 22, and (2) we have a 2004 Honda Odyssey which is
rated for 3500lbs with a trailer fitted with surge brakes. Is it even
feasible to trailer an S2 22 with this minivan, albeit for short
distances? The boat is 2300lbs, probably closer to 2500 with outboard,
sails etc.

My alternative is to have it professionally moved and stored, and
later installed at a friend's slip for 5 months of the year. I would
prefer to trailer it myself and store it myself in my garage's 3rd
stall were I can do maintenance etc. But I'd like to know about
trailering this boat.
