Unifoil
Joel Santarone, the owner of IdaSailor and also Ruddercraft, has developed a system of interchangeable parts that allows him to select from stainless steel components that he has premade on the shelf. Indidvidual rudders are created for each boat type, but the rudder head that he has designed will fit pretty much any of our trailerable sailboats. Either pintles or gudgeons are attached to match the boat. This way, the Unifoil works with the greatest number of boat designs, and if you did wish to get one, Joel can get you what you need.If you build your own, consider making improvements to your OEM rudder. The benefits of a true airfoil design can be nothing short of astounding. Rudder stall angle is the point at which the rudder becomes ineffective, and if you have some weather helm, your boat rounds up. A properly shaped rudder will allow greater rudder angles before stalling, which allows you, the captain, to heel the boat without control loss. Puffs of wind that used to cause roundup, now push you along. My own boat (equipt with a high performance rudder and Unifoil rudder head), will round up, but only at extreme angles of heel, (we're talking water on the galley windows), and as soon as the wind pressure decreases, helm control returns before the boat does much more than a few degrees of windward turn, at which point I am in control again.IdaSailor rudders are a very good investment, whether for performance or safety, but combined with the Unifoil rudder head, the entire rudder system becomes so much more user friendly. My favorite detail is the jack knife type of folding ability that allows the rudder to be left in place, either for trailering or just getting the rudder out of the water. The design works well with a gas strut for hold down, you can expect to see an entire Unifoil assembly with stainless steel gas strut hold down to be offered by IdaSailor soon. Right now, there is a sale on the entire rudder, tiller and rudder head (Unifoil) on the IdaSailor website, check it out. The number of rudders and tillers shipped from the shop is growing, and even larger boats, such as lengths in the 30's, send their rudders to Joel to have a replacement manufactured there. Our boats are orphans, and there is often no where else to go besides IdaSailor, unless you build your own. IdaSailor has the experience, materials and the track record of making rudders that exceed the performance of the often crude factory rudders that were supplied with our 20th century boats. When compared to the cost of a mainsail, a complete rudder set up is a bargain indeed. John S
