I may be getting involved with a custom boat design project/build. More specifically, a high performance cruiser/racer. Ergo, there will be a much lesser need to be able to fully ease out the mainsail
downwind. As the boat will be fast enough to always be reaching, when sailing off of the wind
Thus, part of the project
could entail creating a Bergstrom & Ridder (B&R) type rig for her. Or something close there to. Such as Hunter
did with some of their boats, for example.
The reasoning behind such (a rig) being that;
- There would be less weight aloft vs. a conventional rig. AKA one can use a more svelte tube on a boat with more Righting Moment.
- You can build a light weight rig of this type, which, pound for pound, is more forgiving of "user error", or "interventions of Neptune", than you can with a standard rig.
- There's a "ripe" tube (or 3) available for such a conversion. Well, more or less
- No/less backstay/runners to deal with, vs. a standard rig.
- Built in Standing Rigging
- The ability to carry a huge, highly aerodynamically efficient main. Thanks to the backstayless/less backstay/runner concept
(built into the design).
So, I'm hoping that someone, or several someone's, can point me towards some good info sources, & or references
, regarding the (rough) design(ing) of such rigs. And the critical factors involved therein.
For example, how one chooses a (mast) tube, to begin with, based upon the boat's Righting Moment. And how one decides on what size standing rigging
is required, plus, how it's attached (and to where, as well as how)?
Also, I'm curious to hear feedback (pros & cons) from anyone who's had significant experience/sea time with one (or several) of these rigs. Including anyone who has, or had one on their Hunter
for a while.
Especially as compared to a standard rig. Be it in the racing
, or cruising, context.
Plus, what are the big sticking points, & expenses involved in putting one together vs. a conventional rig? And any & all tips & info on both tangs, & spreader design (& construction) would be Greatly appreciated. Ditto on the design of mast
steps; be they keel
type, or deck
And... of course, anything else of significance which I may have left out, due to being on the steeper part of the learning
curve about these rigs.
Thanks in advance
