ARC17, plenty of buoyancy, can be sailed 1 or 2 up, main, main/jib, main/jib/spin, no boards (nice if you sail in shallow water, or launch thru the surf a lot) strong, quality boat.
There are used older versions available under the name of Supercat 17. I use to sail one at 165lb solo most of the time but it should be an even better fit for you at 240#.
