Has anyone attempted to create daggerboards or center board(s) for their Getaway in an effort to point higher? Better question, was your attempt effective? :)

I have an idea that would be somewhat temporary that "might" work. My concern is that it would involve the makeshift daggerboards being fixed at about 70 degrees instead of 90 degrees. I don't know enough about the physics of sailing but I'm curious if a catamaran had daggerboards that were positioned at 70 instead of 90 degrees would this be less or more effective than the typical 90 degree design found on Hobie 18's, 17 sports, Wildcats etc. Furthermore, I've seen versions of modern daggerboards that curve inward towards the center of the vessel. So I'm curious, if daggerboards have no curvature and are at 70 degrees would this design be more effective at pointing higher than a typical "90 degree no curvature design?"

My makeshift design would be simple and unobtrusive to the structure of the vessel since I'm mostly looking to test the theory of the design rather than destroy my beloved Hobie Getaway. The design involves positioning a simple 5 foot wooden paddle between the wing seats and the hull right where the 7 hole adjusters are for the shrouds. Then secure the paddle at the wing seat and the 7 hole adjuster with LOTS of duct tape (Never under estimate the power of duct tape.) Ofcourse, some sort of protective cloth would need to be placed over the wing seat and 7 hole adjuster so there wouldn't be any duct tape residue left over after use. In addition, a protective cloth of sorts where the paddle touches the hull to prevent rubbing or scratches. Lastly, this fixed design would need to be installed in water deep enough to clear the paddle in the water.

Has anyone else tried something like this? Or know of the angle of the makeshift daggerboard would be effective? As almost any other sailor I'm curious about the variations of designs that may increase the pointing abilities of a sailboat.


What are your thoughts?

This is not going to work or provide any benefit. Period.

A paddle is not a daggerboard. A paddle duct taped to the side of your hull is certainly not a daggerboard. If you want to improve upwind performance, get a boat that was designed to use daggerboards. Otherwise, accept the Getaway for what it is and enjoy it as designed.

Maybe if you attached hobie tiger dagger boards some how to the shroud adjusters in a way so they are solid against the hull, u might see slight improvement. And I doubt duct tape could hold em there because there is a lot of force applied to a dagger board while sailing fast.

A paddle would only slow you down, also angle is much less important than the shape of the dagger board foil. That's why tigers have much better boards than an 18.

SRM is right, the getaway just ain't designed for dagger boards, and if u really want them change boats.

If you want a boat with daggerboards, then buy a boat with daggerboards. The Getaway was designed to be used without them. :wink:

Red Green approved..


I think it is a fantastic plan..


It just won't really work. Not without a proper foil.
