My friend that
sails and races Thistles finally responded. This what has to say:
"I haven't been sailing one lately but have double-handed them a fair bit although three crew is more typical. I wouldn't recommend single-handing one except for very calm conditions in warm
water with competent rescuers standing by. Thistles are a challenge to launch/rig singlehanded. Two crew have a hard time in more then 8-10kts but a reefing or a cut down main could help. The
centerboard doesn't pivot around a fixed pin and can fall out of the
boat (same system as a Flying Scott). The
hull doesn't have much form stability and once the rail is buried the
boat easily floods (no self-bailing
cockpit and many hulls have marginal flotation). It's challenging to self
rescue with a full crew in any sort of waves and likely impossible single-handed."
A house is but a boat so poorly built and so firmly run aground you would never try to refloat it.
