When Marty sailed with me I had a great time - I believe the results were more than adequate! I think we beat you by ONE point for the weekend. That is Marty 'Stretch' in the companionway - a tall drink there! Tell Marty to bring kneepads/shin guards with that GPS as he will need them! (He was most enjoyable , knowledgable and motivated - I had a REALLY good time sailing with him!) You......? won't listen to the voice of reason!! {;>) Take Care, have fUn! Go sail - you need the practice!!!! You can clean up our boat after we 'spank you!'

This rudder is solid one piece of teak. It is shaped but no idea if its the right shape. Guess I need to run into another M15 owner and compare rudders. Wait, that doesn't sound right!!

Doug:

If the rudder was made by Jerry it should be mahogany. As I've no access to a M15 will need to have another person report the measurements or Jerry will comment.

Being short is more of an issue than long. Jerry designed the boat to have a good amount of rudder depth. 'about 1" thick is likely close to correct for a M15/17 width/cord.

Next is shape. Jerry is pretty particular that shape is correct. See -

(Link will open a PDF)

Rudder shape should be an NACA0012.

Using a poorly shaped or matched rudder to the boat will make the boat sail POORLY! A poorly sailing boat is one that isn't going to be used. This is also why your boat should also have sails that are not work out - if the sails on your boat are original or older than 10 years it is time for new ones! #1 reason most boats sail poorly is blown out sails!

Having just bought a M-15 from 1980, I am wondering if the rudder that I have is the right length and weight. This one is made of teak, solid teak over an inch thick. What is the length of the standard rudder for a M-15 and it will be used for cruising and day sailing, not racing if that makes a difference. I sure appreciate the combined knowledge and experience of this group. I saw it in action today in regards to another issue that came up here. Thanks.
