[Rhodes22-list] Electric Motor

Tue Jul 5 21:39:05 EDT 2022

Thanks, Shawn.  I need to figure out how to search for old posts by subject or author.  I’d be interested in what you have written.  

I just need propulsion for inland lake sailing — Lake Keowee, SC.  The wind can be fickle, as it was today when it died completely.
