How about first weekend in October for a run to Fowey on the Saturday, stay over night and head back on the Sunday. Maybe see if the Falmouth boats would be interested.
Eat at Sam's if were early enough http://www.eatoutcornwall.com/cornwa...nt.php?pv=5423
, followed by copious amounts of alcohol and then stay at the old Quay House.
All subject to weather of course
