I would like to 2nd Bob's comments about an anchor and line. It works well.

I would like the comment on the perception of "thinner hulls on new boats"

After many years of watching boats break and looking at the remains I have not seen any catamaran whose hull was significantly thicker and tougher than any other. They all seem to break at about the same point and the remains look a lot alike. They all seem to be strong at the bows, bottom, and hull/deck joint. They are all weak at the sides.

Granted some boats are heavier than others but it's by 10-30% not 100-200%.

Personally I would not want to drag any boat that I have to maintain on the beach, unless I have to. I saw a Marstrom A sailed up on a sand beach in 2 ft surf , last Sunday. The rudder had to be fixed to finish a race. Other than worn paint there was no damage.

By the way in the 70's, Hobie 16's had a reputation for being fragile. The problem was mostly the rigging, it broke a lot. But compared to the beach boats of the day, monohulls with replaceable wooden rub strips on the bottom, they were fragile.

Perception is a funny thing
