plus the wheelm size restrictions, which is a pity as we are just starting to experiment with 20" front ends.
I have to agree that the lack of rules is a bonus. imagine the possiblities of tiny solid wings built from styrofoam.
. here in australia we tend to recycle alot and have managed some really great yachts.aerodynamics are creeping in , but the costs are not going up.
The art of re-using windsurfer sails can really keep the cost down .
In the last year Ive been involved in 4 completely different designs,all with free standing rigs- A low covered light Tframe, a rear plank axle yacht, an OTTwith a high sided body, and a flat Y frame with high body.
all of them have a different feel when sailing and all are incredibly close when racing. so your idea is definitely worth looking at.
One thing to consider though is that a low ,flat bottomed mini has a habit of riding up on a cushion of air at about 84kph. so a wider body might need some serious thought on its aerodynamics
