Do you have a picture of that "break away cleat"?

The older Ida Sailor kick up rudders like mine were offered with an optional break away cleat that releases the "hold down" line if you hit something, allowing the rudder to kick up. Much handier than the shear pin design.
I agree about SCA. Great magazine. I have every copy.

I am adding a 5hp tohatsu to the transom weight also. About 58 #'s. I agonized about getting the 3.5 which is only about 40 pounds but the winds down here just north of Corpus Christi, Tx. are considerable and generate a vicious chop. I talked to Jerry about making the M17 really efficient to windward and he suggested adding some weight to the hull and getting a highcut, 80% jib and using a barber hauler to be able to pull it inboard to about 9degrees from the centerline of the boat and double reefing the main. The traveler car should be pulled to windward as far as possible to be able to trim the main to the jib. He said the boat would scoot to windward dressed like that. I dropped the cast iron board this year and faired the leading and trailing edges to better conform to Jerry's idea of an efficient foil shape. The board ended up weighing only 140 pounds though I did not take any more than about 5 pounds off of it when I was grinding it. So the stock board was about about 35 pounds light as per boat specs. I added 50 pounds of lead to the base of the mast step in the hull to make up for that. I figured the 60 pound battery would then be enough extra weight to get the boat to push to windward. Lots of dithering with these little boats. Good thing I am retired. May I recommend getting a subscription to "Small Craft Advisor". It is a great magazine, bi-monthly, about little boats and the handling, maintenance and improvement of same. Since you also have a kickup rudder you might be interested in a piece of gear I devised to add a slip clutch to the line that holds the rudder blade in place while sailing and will only release if you hit something solid with the rudder, thus protecting your rudder attachment without having to resort to shear pins which are a pain to change out on the water after a grounding.

I have an Ida Sailor kick-up rudder also, and have wondered about the additional weight at the stern. I would imagine, though, that the weight gain is somewhat cancelled by it's buoyancy once the rudder is in the water. Not as much as a wood rudder for sure, but it must be lighter in the water than it is out.

The stock wooden one of mahogany with pintles and sliding ss rod weighed a little over 22 pounds. The IDA rudder I have made of high density plastic top and bottom with aluminum side plates for a hinge weighs in at about 60 pounds. A hugh addition to weight right at the back of the boat. Not good. I may go back to a wooden one and make it a kickup with side plates. Or redo the top half in aluminum plate. My list of winter projects is starting to grow. Tom B

Tom B,
What did the rudder weigh? Type and density of woods (different types of mahogany over the years) affect the weight and ultimate strength
my
last
wood rudder was little better than bad pallet lumber and warped in a few months (stored indoors)
Inquiring minds... That is why 'we' built a plastic one. No warping and mucho control over strength,weight and shape!
Thanks GO M-17t sail # 354 'Tiny Purple Fishes'
