Low weight? 5
Low price? 3 Easy maintainence? 3 Direct feeling? 5 Uphaul function? 1 Downhaul function? 1 Lock-down function? 1 Auto-release function? (when hitting ground) 1 Attractive looks? 1 Dinghy racing? Any further comments? I normally make my own daggerboard stocks. I'm presuming your "uphaul and downhaul" functions refer to strings or whatever, not on pulling the blade in and out in the daggerboard method. If you add "how easily blade goes in and comes out of stock" then that gets a 5 |

A big THANKS!! Hi! I am doing some market research on dinghy and catamaran rudderstocks as part of a university paper. Any feedback on this would be a great help for me. It will only take a few minutes to answer the questions below. Your participation may even result in some better rudder products in the future. Thanks a lot! What do you want out of a rudder stock? Mark with 1-5 where "5" is "very important" and "1" is "not at all important". Also state what diciplin you are in Dingy racing - Dinghy recreational - Catamaran racing - Catamaran recreational. Ok, here we go: Low weight? Low price? Durability? Easy maintainence? Direct feeling? (= no play between tiller and stock nor between stock and blade) Uphaul function? (lifting or tilting the blade back) Downhaul function? (loweing the blade) Lock-down function? (keeping the blade secured in down-position, e.g. with cam-follower mechanism) Auto-release function? (when hitting ground) Attractive looks? I consider myself as representing Dingy racing? Dinghy recreational sailing? Catamaran racing? Catamaran recreational? Any further comments? Thanks a lot for your time!! Rick Andersen rudderstock@hotmail.com |

Just because you asked so nice....

Catamaran racing?
Any further comments?
Majority of Cat Stocks use some form of "Cam" in the stock to lock down the blade. This also allows for a kick up when hitting something. This is where a lot go wrong in that they are difficult to adjust which means they can pop up at speed. hurricane 5.9 stocks are good and simple. Dart are simple but fiddly and my Tornado ones should be simple but I can't getthem right.
For me personally I need a direct feel between extension, connecting bar and stocks, but some F18's use the flexible universal joints between con bar and stock which I would hate. |

Those Carbon winder stocks are the best i have seen, such as the ones used on Phantom rudderblades. |

But Winder stocks have no lock-down function at all, which you've rated 5 Hobbo. Care to elaborate?

Catamaran recreational? I’m a big fan of the daggerboard style 29er/49er stocks. They can be built lighter and with less complexity and can remain attached to the boat all the times. Using them in shallow water when launching is also very easy and the uphaul/downhaul functions become just pulling the blade up and down by hand. Also, hobie 16 stocks are the worst I've never used. |

I'm not sure if its been considered in the setting out of the questionaire, but know a lot of sailors who opt to have fixed rudder stocks, ie the blade does not pivot, its always locked down and the rudder is removed by lifting off the whole system. This is due to performance criteria, it reduces weight and stops "play" from the blade in the stock. Have a quick look at the 18 foot skiff class on the net and you might be able to see a fixed rudder arrangement, or alternatively browse through the 505 and Contender sites, as there may be some discussion on the topic there. We don't have a pivoting rudder on our boat, the blade is in a cassette and operates like a daggerboard through its slot, think the Stealth Cats use a similar arrangement as they have very similar foils. Reckon its the closest thing to having a fixed blade, and the cassette can be packed to get correct allignment much easier than a pivoting blade. Given the choice, would definately not go back to pivoting blade arrangements. |

Just took a trip out to the garage to check Dads and it does have a cam-cleat lock down. However when i looked at it closely it looks like it has been fixed on post-production as you can see where it has been bolted in so i expect the previous owner did it. So my experience of one did have a camcleat lockdown - I'd suggest for the purposes of the research that i like that stock aslong as there is a lockdown on it. |

I'm with you there. The biggest gripe I have with the Hurricane is that if you have any play at all in the rudder you can get massive weather helm. The locking system on the tiller arm is less than perfect and because of the speed we travel at the pressure on the rudders to move aft and out of true is large. |

to all of you who have replied so far, especially those of you who have made comments. Thanks to that I have made a few small changes, see below. I am looking forward to more replies. No catamaran sailors have replied so far. Wrong forum?|
