The WW Potters now come factory standard with rudders made by... www.idasailor.com/ I Email'd them a few weeks ago to see if they intended to create a rudder for the M-15/17. Did not get a responce and really forgot to follow up with the question. I like the construction of their product - however I believe I'd rather have a standard laminated tiller. Check it out... I'll Email them again Regards, Bill
