Dart 18's are great boats for what you are looking for.

In a blow, the boat will sail balanced without the jib. Its boomless and so no worries about accidental jibes killing you when you sail solo. It has a sealed mast with no comp tip leaks or maintenance to worry about so it can't leak and it has foam floatation insede so it can't sink and it was the only beach cat certified by the IYRU for safety. It can be righted by 150 lbs using the jib sheets as a righting line. You really have to work on stuffing the bows down wind...It does not pitch pole. You will never trip over the bows upwind or on a reach. Darts are bit underpowered and rate about the same as a Hobie 16. They carry about 173 sq feet of sail area and weigh in at about 270 lbs if memory serves so they are easy to move on the beach.
