Rudders are twisted in the water, if they are not made from Carbon. The drag and the spape of the standard rudders and the black EPO rudders also cause cavitation. All this is reduced, if you lift one rudder in more wind. In light wind conditions, it does not help at all. Also invite to our seminar, see www.hobiefleet32.orgWe will address all these things there. Fritz | | | Re: Up wind with one rudder

Posts: 170 Australia | This is one of the things of personal preference. I know many of people who kick their rudders up and many of people dont. When the winds become to strong say 25 knots plus, i normaly have them in full time unless i feel i can't control the boat. I also believe it is alot faster when sailing in the light winds to have one rudder kicked up unless you have enough weight at the front of the boat and it starts to become to hard to steer (have seen done) PUT BOTH BACK IN PLEASE. I normaly have one rudder kicked up on reaches but on the up wind leg i have them both in in any thing above 20knots. Its not hard to kick them up and not hard to put them down if you drop them just before the tack.
Problems with your rudder being up is well if you forget to put them down good luck steering. in waves on a reach the rudders go in the wave and make it hard to steer. You cant ber away easily. More time wasting if you cant do it properly.
Advantages are less drag. Can make it easyer to stear if you rudders arn't set up right. Faster way of sailing.
Well work on it and have fun.

Posts: 170 Australia | It doesn't take much to kick them up and down so try it an get use to it. I noticed in the Austrailan hobie cat nationals the only people who left their rudders down where the people at the end of the race course, all th top guys were doing it. Well I also noticed the french guys also do it and they are preety decent sailors to be beating some tigers around the track. I think it comes down to the type of boat which it works on and the hobies need it. In terms of having a hull flying, the rudders should be in the water since its faster to sail with the hull just skimming.

Posts: 106 West Texas | I wanted to add another thought: I usually do not kick-up a rudder unless I am sailing a long downwind in light air conditions. We do sail about 100 pounds overweight, and I have found the extra boat movement and me being too far aft, tacking rudders and such, really hurts our performance. We are much more competitive making smooth gybes and tacks, which are difficult, when the skipper is on the back of the boat tacking rudders.
It is impossible for our boat to go as fast as the light weight crews. We are heavy. But! This does not mean that we cannot be competitive. Tactics, is crucial. We have won races, taking the right windshift, from last to first place.
We sail in B Fleet, and sometimes can compete with many of the A Fleeters. Last year, the winds were non-existant, and I was struggling to get to the starting line to start with B Fleet. I finally made it to the line, when C Fleet was starting, and gave way because I didn't want to mess with their wind. We started after C Fleet and managed to finsih in the middle of B Fleet finish. All of this happened because I watched both fleets sail into a "dead hole", tacked to the other side of the lake, and passed most of the boats to the windward mark.
Food for thought, David | | | Sequency

Posts: 256 North Europe, Sweden, Uppsala | I've been sailing upwind with one rudder one on many races for approx 10 years. I raise the rudder from single trap and higher winds. In lighter winds you need all the rudder area you can get!
Step by step 1. Your sailing with double trapped full power with one rudder. 2. Luff the boat gently and jump in from the trapeze when you are heading directly into the wind. 3. Crew jumps over to new side. 4. Skipper pops down the rudder, releases a bit of main sheet and jumps to the new side. Since the skipper is slow over to the new side because of the rudder you get the benefit of a roll tack also. 5. Gain speed on the new tack with both rudders and start sheeting in the main.
Now you have two options Option 1 6. Gain some more speed so you can sheet the main in a bit more. 7. Raise the rudder 8. Go out in trapeze. option 2 6. Go out in trapeze and sheet in the main for max power with both rudders. 7. Go further back in the trapeze and kick the tiller up with your rear foot to release the kick up. 8. Kneel in (stil in trapeze) and pull the last bit of rudder up to locked position.

The key issue is that you can't sheet in the main after a tack and get speed on the boat with one rudder only. You need some speed before the rudders have enough "bite". /hakan Picture was taken during a Hobie raid in the Swedish archipelago a couple of years ago. | | | Re: Sequency

Posts: 170 Australia | Hi harken, you have given great advice and i agree with almost every thing. Well you can kick the rudder up first before picking up speed, all you hav to do is steer more with your sails which is ok but i feel it can be a bit slow but you dont have to worry about it when your trapezing.
