OK, I'm gonna swap it back out to the old one. When I learned how to sail in college at UCSC 30 years ago we had some really wonderful racing keel boats known as Shields. I think there is still an active racing class. In any event, these things weighed about 6000 lbs, and were 30 feet, but made for 2 sailors. Bendy masts, full spinnakers, the whole bit. They had keel rudders that did almost nothing, so the boat would really go only where the sails were trimmed. Made one a better sailor, for sure! So in one of the intermediate instructional classes one of the skippers was sailing in the harbor back to the dock under pretty good wind. She was headed straight for the dock, and was pushing the tiller away to steer the boat to avoid the dock, but because of the way the sails were trimmed the boat just continued on its merry way. The rudder did nothing at all. So, she panicked, and jumped into the water off the transom leaving her crew mate in the boat to crash into the dock. The instructors were beside themselves. But, they were experts at fiberglass repair... Daniel On May 14, 2011, at 1:38 PM, W David Scobie wrote:
IMO to stall the M15's rudder you have already significantly overpowered the boat.
i've never stalled the rudder on any of jerry's boats (M15, M17, S17).

In the M15 review years ago in Small Craft Advisor somebody complained that the M15 rudder would stall. But that has not been your impression? I will look over my tiller and rudder assembly, and if it looks easy, I may swap back to the wood blade for a while to try it. The shape looks just like what Jerry describes in his article. One would imagine he designed this rudder to work well with the boat. As I said, my main issue is the weight of the much larger plastic blade. But if the wood blade works well, I could even put the rudder on before backing the boat into the water. That would actually help a lot.

the ruddercraft rudder on the M15 is heavy when compared to jerry's wood design. the M15 is less forgiving of having weight aft than the M17. you want the M15 to be very close to level on the waterline (bow to stern) when off the wind, or just a bit forward on the bow to get the best performance when sailing to weather.
i never felt the M15 had any rudder problems. some feel she can have to much weather helm ... but to me she is just giving you important feedback you are overpowering the boat and need to reef the main.

Interesting. I have an Ida sailor blade installed on my M15 stock tiller assembly,
and have
the old wood blade in my garage. They were like that when I purchased the boat. The previous owner far preferred the Ida sailor blade, as it is deeper and he felt he had better control. My complaint with the blade is it weighs a ton, and since I can't put the boat in the water with the rudder installed on the trailer first, since it droops down and might get wrecked, I have to install it on the water. Wrestling the thing into the gudgeons is hard! So, do you think the performance of the stock blade is pretty good? And if so, should I reinstall it and try that?

Anybody have thoughts on this subject and while we are at it is an IDA rudder worth the investment for a M 15?
Thanks Smiley
