The UK has a 12ft skiff just minus 2/3 of it's rigs.... it's called a UK
Cherub.

Avaliablity is an interesting word. 12ft skiffs / UK Cherubs are freely
avaliable. You just need to get a boat builder to build one or build one
yourself. The plans for both are freely avaliable.

To build a 12ft skiff in the UK you are looking at around £17,000 perhaps
more.
A UK Cherub is more like £8,500 / £9,000 i.e it only has one rig.

Interest in the UK Cherub is high, so yes 12ft Skiff would / will become
popular. But you still need the skills to sail one.

does anyone else think that if 12ft skiffs were more available they would become quite popular, they are lookers and seem to go very well indeed, in my opinion they would plug a whole in the market. any other opinions as i may be completely wrong, anyway just a thought.

Why doesn't it class as a skiff, it planes upwind and downwind and when we did round the island we had 3/4 of the boat out of the water on 2 sails!

Why would you say not a hope?

Nope. No way. Not a hope.

The Ultra 30's did have a daggerboard but it did take 4 of us to lift it.

Awesome skiff thats for sure, shame they died out because of the Olympic coverage.

Didn't the Ultra's have a retractable keel? (remember, loads of guys had to stand on them when things went wrong). I reckon an 18 would be quicker than an Ultra 30 just due to the weight to sail area ratio. The 30s hull wouldn't unstick as much and as well as an 18s. The drag factor on a 30 would be much higher, so can't see them producing as much overall positive lift neither.

More sail area doesn't equate to more speed - in fact its the opposite.  Once the sail has to be flogged you go considerably slower and you go a little bit slower if you have have part of the sail backwinded.  The ideal is a rig which is just big enough to keep you fully extended - at that wind speed and angle.

I believe ice yachts are an example, for maximum speed the rigs are too small to give any acceleration at low speed so the pilot has to get out and push.  Once going the apparent wind increases and there is enough to accelerate the boat to higher speed which in turn increases the apparent wind even further and so until they are overpowered and they have to ease, at which point they are at maximum speed.  You know the record is around 150mph!

This is one of the reasons the Laser4000 is so fast, it has a modest sail area (if you can call 31 sq m modest) and so can be thrashed in a 25knot breeze.

just been trawling through some old photos of when the Ultra30 fleet visited Cardiff.  I have some pics with the boats on their trailers.  Definately have dagger boards cos on they're trailers they sit no higher than the roof of a Landrover etc

might have a keel, i dont know, but does that automatically make it not a skiff? that sort of goes back to the 'definition of a skiff' discussion that every one keeps talking about.
