Rudder alignment

[George]

Need some advise on Rudder alignment. I've been told it's best to have the rudders toed out. is that true? In any case, here are shots of my port and starboard rudders. The outside of each rudder shows wear or burn, while the inside shows nothing at all. Would seem to me to be cause for drag and lessen performance. what do you say?

Yeah, I would like to know also. I cant imagine why that would be the case. If it was a car and you are going around corners fast, tow camber (leaning top in) the tires in. Towing in just wears them out. Maybe towing the rudders in helps with stability. If the rudders are towed in, then when you turn slightly to one side or the other, it seems like one of the rudders would'nt turn as well as the other. I cant see it. Maybe a professional (no an expert) will chime in.

Slight tow on the rudders (stabilizers too) prevents them from chattering. There is some normal play in the system and the 'tow' keeps pressure in one direction. The argument I have seen for outward tow is it directs more water toward the boat and provides lift. Sounds logical but who knows. And I never stayed at a Holiday Inn Express.....

Holiday Inn...Ha-Ha.. Thats funny right there, and I dont care who you are (Larry the cable guy). That makes perfect sense. I'm gonna turn mine out 45 degrees and see if I can gain 10 or so knots. I have looked at my rudders while under way and I've seen that flutter thing going on. Naa really a couple degrees should hold some pressure on the rudders and stop the vibrating. Good point.

According to Hatteras, when I asked via email and received a response re toe on my 53MY, their tech responded that the toe is 1 to 1.5 inches and can be either toe in or toe out. I set mine up with the aft ends of the rudders 1.25" wider than the fronts.

Long post on all this in '09 here, including the above statement: http://www.samsmarine.com/forums/showthread.php?13187-Rudder-Toe-In&highlight=rudder

George, aft edges closer together lifts the stern, aft edges further apart lifts the bow. Rudders straight will flutter and scare you friends the white marlin away. Didn't you just have all of this apart in the spring? When was the last time the rudders were painted? Happy Thanksgiving.......
