Gareth,
I'm both encouraged and discouraged by what has been going on in these discussions. So much enthusiasm yet still so much bickering.

I have been trying to work out why this is so. I think apart from the personal differences hear I think we may have two completeley different objectives.

On one hand there is a group that just want to get young people into the sport. Mostly people that you would not hook otherwise.

Then there is the group that are in the sport and want to get the best they can to introduce their own offspring to the sport or give the young ones they know in the sport the next step in performance or just design the best performer given the anticipated rules.

So in answer to your question I have two hull shapes in mind.
One will perform well but is essentially a fun boat that can be built in a very short period of time at very little cost.
The second is a more refined craft and given that I still have a desire to maintain simplicity and even with the physical limitations in this size it is a race boat. The race boat is for experienced kids and light weight adults.

The first shape is aimed at bringing people into the sport and if push comes to shouve could be built with a knife, screw driver, saw, plane, hammer and tape measure.
The magic in this is not in the refined hull shape but the method of construction, time involved and cost.
I think this boat will still give the newcomers what they need to get hooked.

So rather than share this with the forum and blow more hot air. I will try to clear some time in a few weeks and build it. Documenting both the time and cost. I need to build an F18 plug but straight after that I'll get it done.

It's time we saw something we can touch.

Regards,
Phill
