Design and manufacture can meet any classification society rules, including all iacs societies, and rudders can be cast in a range of materials to suit the specific application, with nickel aluminium bronze (nibral) or high tensile bronze representing the most popular choice of material, equally, cjr’s rudders, can be manufactured using a. Rudder stocks have to be very strong to be able to steer consistently at such high speed. i favour using stainless steel or titanium, rather than carbon for rudder stocks, because at least the rudder will bend if overloaded, instead of shearing off. i design for a factor of safety of 1.5 with rudder at 90 degrees to the waterflow at 25 knots..

high speed boat rudder design Extremes of sailboat design. let's explore the middle ground, where most boats reside. table 1 lists the key criteria for the design of keels for racers and cruiser/racers. simple planform keels the "simple" or "standard" keels such as the one shown in figure 1 would include high-aspect-ratio keels as well as low-aspect shallow-draft keels.. All such high-lift rudders can be thought of as propeller slipstream diverters since they get their low-speed, high-angle lift by changing the direction of the slipstream radically. though articulated rudders can work well, they have moving parts and are thus more complicated and expensive than fixed-geometry rudders..
