Plan Shape Maximising parallel rails
	
	
Wide deck at tail to give leverage against fin, which is good for up wind sailing on fin.
	
	
	
Cut outs at tail to reduce wetted surface & drag for higher top speeds & give better control & easier to gybe.
	
	
	
Tapered tail plan shape, to help gybing & up wind performance on dagger board or fin.
	
	
	
Minimal nose rocker for better rough water control and smoother transition to plaining with gradual change to a straight vee exit in the tail for better top end speed & control.
	
	
	
Sharp Box rails from front of mast track to tail.
	These help with pointing high & directional stability when sailing up wind on the fin or dagger board & reduces reliance on the fin for pointing high when sailing up wind.
	
	
	
Soft rails forwards reduce drag, help with control & wave piercing.
	
	
	
Straight Vee with reducing concaves.
	Vee for smooth ride when sailing flat and easier to sail on heel and generate lift from foils & concaves. Parallel vee to give a faster top end speed, better rough water control & prevents the nose from flying up.
	Concaves deeper forwards & flattening towards the back, generate lift, promote early plaining & improve top end speed.
	
	
	
Slight dome deck to add stiffness.
