Small multi's: ARFs and kits

To amplify on an earlier post, here is a set of links to manufactured multihull models.

I had incorrectly attributed the new FIDGI 60 to Robbe – it is evidently French, from ?quippage. Very ARF, a snap together, according to the ad copy.

In studying the photos I notice on a couple these designs some very generous keel fins. Not clear if there are bulbs as well.

The Dumas Hobie cat text declares that is is not intended for r/c, but as noted, I have seen it equipped with an arm winch and a tiny rudder servo.

I have also seen at our pond a very much modified Wildcat. The builder used the hulls, and everything else is original. It moves in the lightest of light air, when the pond is glass and everything else on the water is dead still, this little catamaran goes skimming along like a waterbug.

Never been sure if this would work, but I think the key to these small multis is in the application of electronics. Specifically, the tilt sensor chips (now commonplace and cheap), accelerometer chips, and perhaps r/c gyros of the type used in helis and touchy, short coupled airplanes.

The idea is to have an onboard gust sensor anticipate a flip, and do exactly what you would do if you were on board and had the reflexes of a cat, that is, throw away the sheet overhand and try to get the bow into the wind.

In addition to the electronic abort, you could also make it easier, with a null seeking chip preset to seek a certain angle of heel – to fly a catamaran on one pontoon.

Without some onboard electronics, imho, I don’t think these little multis will ever be quite perfected. Human nerves conduct information at just 300 mph. Chips can react at the speed of light.

You can’t move a servo at the speed of light, obviously, but with a solenoid you could very quickly pop open a sheet release ring, or unlock a shroud and let the rig fall flat.

Anyway, food for thought.

I saw a Fidgi 60 in a local hobby shop on thursday. I was told that it is made in Vietnam. The main hull was made from stripped balsa. They retail for $395AUD over here with sailwinch and radio gear.

Could be a good boat for the kids to get into multihull sailing, but seems abit expensive to me.

On a different subject. Our titles are on again here this weekend, so I will be sailing the new boat that is finished. It has been sailed and fully tuned and goes like a bullet. Makes my old boat seem very slow.


Re the Fidgi, there seems to be quite a spectrum of prices. Converting to USD, I get prices as low as $233 (from France) to $300ish (Australia) to $320 (England). The boat is sold with and without radio, so this must account for some of the variety in prices. Another factor is VAT, which can be subtracted out of exports. Have not seen a US distributor. I admire the shape of the Fidgi’s sail. But the Jamara trimaran is similarly priced and appears to be made of plastic.

As yet no photos hopefully will be able to publish some this weekend. Depends if we have someone there with a camera.

I can tell you that I haven’t seen a r/c tri multihull that tacks quicker in 5-12 knots of breeze and excellates as quick. This boat would be quicker than any multi that I have sailed against (including the Ballina boat but excepting 2 meter).

It lifts the main hull in 7 knots of breeze with full rig and at those times points higher than any r/c boat i’ve seen. Without reservation I would say that it points up to 13-15 degrees off the breeze and still sails very fast.

It weighs 3.1kg fully rigged with battery etc.Without rerservation the fastest boat by a long way that I have built to this time.


I’d love to see that boat…


_/ if it isn’t broken, don’t fix it! _

here is a distributer in the us for the fidji ,i could not find a price. go to

such is life!

Thank you for the link. I will pursue it and report.
