I use it my M15 even for extended cruising ( 5 days or more). It fits nicely where the porta potti normally goes and if you move the plywood cover, put a boat cushion on top of the Pett box and the back and slide you legs under the cockpit you now have sitting head room to read by. The only mental adjustment is getting use to a three legged stool that is high in the back two legs. You cannot lean to the side to.... well finish the job. The stool will tip over. Highly recommend it though.

For my purposes--mostly day sailing, sometimes longer days, and occasional overnights--the Pett is the Bomb..seems to fit the bill perfectly. Most days, when I'm out on a local lake for maybe 3 hours, It will never get used, so I wouldn't expect to go through bags very quickly. Also nice 'n light to carry ashore for remote boat-in shore camping if there are no facilities. As for the trying out with a bucket and just the bags--that will flunk the WAF (Wife Acceptance Factor) test. I'm sold and plan to order one. Just waiting for an answer if someone knows if it will sit assembled (3 legs down) in the well in sole of the M15 and still be low-enough profile with the lid down for clearance under the plywood cover that supports the cushion above it. Looks like it will... Thank goodness for this forum for helping me avoid a -ahem- crappy $100 mistake Neil _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats Remember, there is no privacy on the Internet!
