[Rhodes22-list] Sailing electronics.

[Mary Lou Troy]

Bill,
I think that was us with the fishfinder transducer mounted on the PVC 
pipe hanging from the stern rail. It works well and doesn't get 
fouled because it can be raised out of the water when not in use. We 
use the depth mostly for navigating (in the channel?, out of the 
channel?, following a depth contour around a point of land, etc.) 
Don't have time to hunt for the links right now but I posted pictures 
in January 2006 if someone wants to hunt it up in the archives.
