How Come You Don't See More Outrigger Sailboats ?

It seems like the advantages of polynesian style sailboat building have been embraced by the catamaran/trimaran community

still, the outrigger model seems to be relatively rare. Is there a functional reason as to why the sailing community prefers the more symmetrical style of boats?

I agree with all comments.
I prefer a mainhull with outrigger concept in preference to the catamaran. This gives a better use of interior accomodation and much lower cost of construction.
To overcome the "space" situation you can fold the outriggers like Farrier or Dragonfly.
Another alternative which is becoming popular in the large ferry multihulls or powered "trimarans" is to mount the outriggers much closer to the main hull "stabilized monohull" or "mono with training wheels"?

This concept allows the use of fast non displacement main hull designs with the stability of the outriggers.
Another advantage is shallow draft.

I am really appreciating the higher speeds available and I am replacing two 30hp Honda's (max 10 knots) for two 90Hp Tohatsu TLDI two strokes. I will let you know how she goes.( i hope to cruise at 12-15knots, with a max approching 20 knots.)
I will still use the sail for downwind economical cruising.

I am in the process of modifying "Beau's boat" to be be more "powerboat orientated" the outriggers are being moved further back with a 2ft gap between hulls for overall spec's of 39 ft long X 15ft wide.
However the outriggers can still be folded out to 22ft wide for sailing if needed, but because any sailing will only be downwind this may not be necessary.

Thanks for the responses

I might need to reword my first question though. What I was thinking of is the monohull design with, in leu of a keel, an outrigger like this picture only larger



I'm guessing to some extent, but I understand that having multiple hulls is an alternative to keels that adds stability and speed by reducing drag. If that's the case, then you think you'd seem more of the monohull design with an outrigger, or maybe an outrigger kit out there that would let you replace your keep in this way.

Is there some engineering issue with that idea that makes it impractical?

I feel like that would be impractical on a much larger vessel, The outrigger would have to be almost the exact specifications of the hull wouldn't it? Although it looks very stable.

I'm not sure

if it were replacing the keel, then it would have to contain the same degree of force required to keep the boat upright. I have no idea what that is, and at this juncture I'm not going to venture a guess except to say that unlike a keel it would have to be buoyant as well as heavy.

What size monohull do you have in mind.
The overall width necessary for safety at sea is probably the biggest setback for a sailing boat with outriggers.
Monohulls with keels are very forgiving.

There is also an interaction between the waves produced from wide monohull type hulls which can cause singnificant friction, slowing the boat down.
This is why modern designs of multihulls use fine entry, and narrow hull shapes designed to minimise turbulance and friction.

Harryproas are available in 5m/15' (production boat, $US3,500), 6m/20' production boat and various cruisers and racers up to 26m/85'. There is a video of a 15m cruiser sailing pretty effortlessly at wind speed at .

regards,

Rob Denney
