What's the logic with the high aspect rudder ? More or less likely to stall ? Better at high or low speeds vs standard aspect ratio ?
Congrats on the boat's launch.
You need a lot of bite to keep a boat like this on its feet, and maintain steerage. The J/90 had such an undersized rudder, you had nothing to say about it. It would round up and wipe out with no warning. The tiller would just go limb. You also could not sail the boat down hard without first easing the main hard. A lot f the rudders on 90s and 125s were replaced with high aspect ones, and it cured a lot of the bad behavior. J Boats got in front of this one with the rudder design.
