Thanks for all the great ideas. A few questions from this newbee - what is the "long purchase system" in PTP's response and what is a 2/1 or 3/1 purchase in Pepin's response? Boy I have a lot to learn! We are actually in North Carolina but thanks for the offer windsurfingsteve!
A purchase system is an assembly of blocks and rope. Like the mainsheet on your cat. When saying 2/1 or 3/1 it describes the number of strands between the two blocks, and as such the number of feet of rope you have to pull to move you boat one feet.
As an example your mainsheet system is probably a 5/1, your jib halyard is likely a 2/1.
For your application you probably don't need marine grade blocks and rope, you can find some cheaper alternative in a builder yard.
