i can tell you reefing a sail on a boat with a halyard lock opens a real can of worms.

you will need to lay the sails on top of each other to evaluate the usability of the prindelsail on your boat. modifications may need to be made...or not. the prindle has a boom, but for recreation on your boat, if the foot lengths of the 2 sails are similar, boomless may work with the prindle sail.
