Carl,
I had a post in the thread on the open forum (F14 subject) but deleted it as soon as I saw the min weight.

I was working on a 14 ft design but I'm just not interested in designing a boat that heavy.
After all the work put into developing the Blade F16 hulls and the pleasure expressed by others when they have had the chance to sail Blade F16. I started working on a 14ft version. I will still design and prototype the Blade 14 but it also looks like it will not be involved in the F14 class as proposed.

The basics for the platform are worked out but it will also be as you put it "way too light".

I don't see any reason to design a heavy boat. They just don't interest me.

I'd like to see the F14 class accept a broader cross section of craft.
It is proposed that the min weight be 240lbs which is around 110kg (actually 107) and sail area of 160 sq ft.

Now if we design a boat weighing 70 or 80kg and give it that sail area (160) it will kill the class straight off.

I accept that point and would like to propose there be a sliding scale of boat weights and sail areas.

That way as well as giving seasoned sailors a low cost way of competing and tinkering it could also be a motivation to design some modern looking 14ft craft and these could be a vehicle for attracting some of the younger set into the sport.

Sample table of sliding weights and sail area.
eg
110kg = 160sq ft sail area
100kg = 150sq ft sail area
90kg = 140sq ft sail area
80kg = 130 sq ft sail area
70kg = 120 sq ft sail area

Just to get an idea of relative weights areas and ratings.
In Austrlia we already have two popular 14ft boats that would weigh in around 70kg fully rigged and they are more than 30 year old designs.

Arrow = sail area 111sq ft weight 70kg rigged approx with a VYC rating 91
Paper Tiger = sail area 101 sq ft approx 70kg rigged with a rating of 91.5 under VYC this could be compared to Hobie Turbo which would approximate the rules VYC rating 88.5.
If building specifically for the F14 you could increase the sail area on the PT and Arrow to 120 sq ft and you would be very close to the H14T.

Both the PT and Arrow are very simple to build but I couldn't see anyone likely to build from either of these plans just to pour 40kg of concrete into the hulls just to compete in the F14 class.

Just the way I see it.
