[Rhodes22-list] CenterBoard Angle-Tiller-Test

Sat Mar 10 23:00:06 EST 2007

Art, 

Let me know how that works.  Last time this was up for discussion, I thought someone had a pretty good idea with a pair of locking oars.  If they could be designed like a two-piece custom-made pool cue Leroy Brown, they'd fit nicely under the seats when not in use.

Lee,
If you are looking for an alternative or backup for short distance transit, I am just about to do a trial run on a skulling rudder blade I designed for Mary Jane.  I'll keep you posted if you want.  I don't think I would give up my 4s Tohatsu for an electric.  If need be, I'll just paint it green...
