Location: maine Maybe a molded paddle to prevent sheets catching it, nonskid on each side. There should be an instant release device too, or one on each side (where you'll be if all goes haywire). Location: maine There are the cup racer minis, but with deep-bellied underbodies.
Most canting keel boats are significantly narrower than fixed keel boats for this reason and to keep wetted surface down. There is a downside to canting keel boats that hasn't been mentioned( as best I can tell) and that is the extra lateral resistance required upwind when the keel is canted. Chris Ostlind Previous Member   Actually the word is could, Doug and not would.
Some folks simply find out that they don't want more complex boats with more things that can break or go wrong. Now look at the trouble that American car makers are in after not realizing that lesson much earlier in the game.

A wider boat allows the single crew to get his weight further out, offering some exhilerating performance in otherwise reefing or spilling wind conditions.
Initial stability is all a small canting keel boat has to provide control under conditions when the keel is being shifted. While a narrow hull could be kept on its feet up to a point, enough weight to make a big difference would be too heavy, and sails would become less efficient heeled. Performance keelboat ideas Alan, replacing a second crew with a canting keel could make a great singlehander as long as the limitations of the canting keel were understood and allowed for.
A bit out there but not because of complication but because it hasn't been done yet on a monohull keelboat(as far as I know). Another way is for the weight to be inside a big float, so large that it gives more bouyancy than righting arm. An air cylinder aboard would negate the need to pump manually, and would transfer very quickly.
Water could be dumped any time and picked up any time, so running would be faster and the boat could be quite light. But the ballast need not be so much to get the righting arm either, which makes a faster boat, and flotation is possible without what looks like a buick on the end of a pole. I imagine a lot of multi-hullers are reading this and saying to themselves, "Keep going.


I think there is a lot of potential in combining technologies for moving weight with foil technology to produce an extraordinarily fast monohull keelboat-equal to or faster than multies- that trumps the multihulls by being self righting.
In the meantime, I think a boat about the size and type of a Bongo with a canting keel would be a real blast!
And if small monos (windsurfers, moth, et al) can beat multis for out and out speed on all points, that's the boat I'd like to pilot.
Really, such a system would work nicely on performance cruisers or dayboats, keeping the mechanism all inboard (and able to be collected down low in the hull if desired).
I'm reminded of a couple of excitable teenagers who are egging each other on in anticipation of tossing waterballoons at passing cars on the highway.
The funny part about all this is the ironic observation about finally coming round to the position that you're both desperately trying to make a monohull go as fast as a multihull. While you are screwing around with a canting this, a sliding that and a hydraulic something else, the multihull sailor quietly un-rigged his much less complicated boat, towed it home and has a really great BBQ going with a cold one in his hand. This may not make sense to you, but there is an indefinable elegance in integrous shapes, a sense of compactness and efficiency.

Essentially, Alan, you have formed a technical argument around what is principally an aesthetic preference. The desire to reach for that technical position which is already being done by another, very successful, form is where the focus of the discussion rests. These systems will add undue expense to what is probably well on its way to becoming a pretty nice style of boat.

When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
Edit:Technically, one of the advantages of canting keel boats is the ability to reduce beam thereby improving upwind performance in waves.
And, really, isn't it all up to whomever designs said boat and not what you think it should be? It's not gadgets, gee-whiz and big engines that sell cars and it won't be any of that which will get the boating market out of its small craft doldrums, either.
I agree that it is far better on a small keel boat designed to plane to have the keel weight move to weather rather than stay in the center. On-deck sliding ballast would be easier to move than a big canting keel and could be moved to weather farther.


And I'll post a couple of model pictures that illustrate a sliding deck ballast system that leaves very little to leeward and is supported by a Trapeze. If the multihullers are saying that I'm not sure they'd be right: one guy did an analysis of the 60' monofoiler showing that it could be competitive with an ORMA 60 trimaran! And for the first time in history a monohull is faster than most multihulls under 20'-and an 11' monohull at that. Do the same with a bone clean example of the same craft without the extra stuff and then get a number pulled together for a catamaran of similar length.
There is a segment that likes to have the latest, go-fast toy material, but it's far from being a commanding market share. Thats one thing I had a hard time with on the Bongo-it was designed as a planing boat and designed to be sailed flat. It could be a water bladder on a smaller boat; in a bigger boat the tank could be inside a wing shaped cross arm.
But, integrated pumping systems for slurries of whatever type, are not at a lower cost, or with lower maintenance, when compared to a simpler design. I think it's a modern man thing to seek-out an overly technical solution for things that have already been solved through other, less complicated, means. Add stuff that is ultimately fiddly in nature, maintenance committed and weight generating and you have the makings of a rather interesting one-off exercise, without much value otherwise. Isn't the small boat environment already in enough trouble as it is, that we don't need to add to the confusion for the consumer with yet more promises of salvation through technology?
Beam for RM can be achieved with a narrow waterline beam by using something like carbon racks - small weight penalty for a large RM.
Bethwaite first proposed the idea of sliding deck ballast in the present era on his 60' Maxi Skiff Pterodactyl.
Likewise, the canting keel is going to add expense, as well as an ongoing maintenance issue not present with a non-canter. Keep in mind that your most likely view of this boat will be from the aft end, so perhaps it's unfair to show the bow view as an illustration of its beauty. This is something along the lines of what your partner, Doug, would suggest as the potential monohullers multi beater, whether you know that or not.
