Sailfish hulls cheap
|
Kinda makes you wonder: "do you tell them what they really have", and, having windsurfed a few times in my youth, nowI'm curious as to how well that works on a Sailfish, assuming you used areal sailboard mast, gooseneck, and booms... ?probably more stable than a conventional purpose-built sailboard?

It would be interesting to see, but I suspect that the position of the mast/rig (fixed) ?in relation to the daggerboard (fixed) would mean that it would be way off-balance. I only have a bit of experience windsurfing but given the way that the steering depends on where the COE (center-of-effort) is, based on tilting forward or aft, I think you'd have some serious problems. I've also noticed that many/most of the windboards have multiple positions for both the rig and the daggerboard.? I don't know any of this for sure... It might just work! But I have my doubts.? While we are on the subject: Imagine your (modern) Sunfish rudder. Now take the blade and turn it around in the rudder head so that the trailing edge is now the leading edge. That is what the Sunfish Class has approved for competition.? Tom?

开云体育Min from advisory board.... Change Rudder Angle To A More Vertical Rudder It was proposed and approved after a long discussion and a year-long evaluation period that a modification of the existing rudder to achieve a more vertical rudder Add Rule 3.3.3 The Sunfish rudder may be modified by drilling a new pivot point hole and attaching the tiller bolt where the original pivot point was so the angle between the leading edge of the rudder and the centerline bottom of the hull is no less than XXX degrees. The modified rudder shall match the template provided in appendix XX. A skipper may choose to sail with a standard or a modified rudder as long as they do not change during a regatta. XXX degrees is to be measured and included as part of this rule Rationale A more vertical rudder will improve safety by: ? The improved rudder effectiveness across all windspeeds but especially in strong winds will offer more control and prevent dangerous frequent wipeouts due to the current rudder’s swept-back design ? A massive reduction in tiller loads will decrease health risks associated with typically very high tiller loads, especially in strong winds Furthermore: ? A massive reduction in tiller loads will make the boat more appealing to youth, women, lightweight and master sailors in the class ? It will prevent the common breakage of cheek plates ? Nearly zero implementation cost ? Reduction of scullability will reduce the temptation to engage in this illegal practice ? It will improve the experience of sailing the Sunfish in every condition but especially in stronger winds. This has been proven by experimentation and the zero-implementation cost makes a welcome change for the class. These benefits can be user-installed without special tools or skills.

Is there a link to photos of the mod process and implementation?

The rudder change has been submitted to World Sailing for consideration. The ISCA Advisory Council approved a proposal, sent it to the ISCA World Council which approved the potential change, causing it to be eligible to be submitted to World Sailing.? The minutes were poorly written and should have stated implementation cannot occur until the proposal is approved by World Sailing.? That can take 1-1/2 to 2 years.? Making the rudder blade more vertical is reported to make loads on the tiller lighter when it is windy, making less deflection in the tiller, lower loads on the rudder cheeks, easier to steer.? In weedy locations may prove to be a problem.? TBD.? If it is approved by World Sailing, watch for far clearer information and how to's, but it's going to be a while. People who are good with tools will have an advantage. |
