This produces, when turned, an undesirable component force which puts the bow down and results in more drag than a rudder blade which is has its leading edge at a right angle to the flow of water. This may be desirable when the blade is turned at great angles to slow the boats forward motion prior to starting, however it is unclear what the prime intention of the designer was in doing this. More observation comments would be interesting. The rudder tube is angled forward which, when turned, applies a paddle effect to the ruder blade.

It is great to see the top boats very close up and have time to study them in detail. All the best Colin Hi Anders,
great detailed pictures and comments anymore will be much appreciated. It is great to see the top boats very close up and have time to study them in detail.

All the best

There should be a slight increase in leverage and strength. Thank you for the camera eye view. Michael Anders,

He commented that his sail control lines still shrink, which is a problem he is still working to address. Thanks for the great shots and commentary. Brig Anders,
