What some owners and builders say:
Dennis Murrow.. Stardust, Catalina 27...Sails this boat better than I can on any point of sail so long as there is steerage way..1998

Billfred Green, Sans Fruscins, Columnbia 8.7.."This this is strong reliable, and a great help" Just before Katrina where the vane took no damage at all...

Jim Muri, Outatime, Columbia 9.6 " I used an  8" diameter drum on my wheel. This thing really works! This is a good design, DR Dave, I hope you sell a lot of plans for it..
