Todd,
The very knowledgable "Catamaran Boat Mechanic" Mr John Schlossberg has been working w/ Mark Schnieder on a Mid-Boom Mainsheet Sheeting System w/ cleating for Mark's A-Cat. They've been working on it for awhile ... John makes the parts .... Mark breaks the parts ... John makes new carbon parts ... Mark breaks the new parts and has to buy more beer ... but from the last reports they are getting close to a system they are happy with ...
E-Mail John or Mark and find out what they have developed
Harry
