Sorry Kami I find your english a bit hard to understand - can you explain a bit more, what I have found (in my limited experiences) is that I do not like the square nose of a vangard shape board - I think a more traditional pointed nose with a pulled-in tail (not big and fat) with thin pinched rails is more suited to my style of surf riding (and I am still experimenting) but for a super short board you do need a bit more volume and thickness all round - it is just finding the correct balance, And as far as what Colas (the master himself) says I totally agree :-)
Dont be sorry about my english as well of I agree I have been confused in what I wanted to explain .
I try to explain that 7'4" or 7'6" pointed nose get a wide point forward the center despite shortest pointed nose of 7'4" or 7'6"are still too long to get the widest point of the board around or close to center and/or outline hips between feet .
Widest point is the most important parameter of looseness and so all the pointed shortest SUP are still looking like mini gun ( 7' short board) rather than a 5'8" beach break board.
This is why Vangard style get a square nose, it's not the fact to get square, outline get square at nose when you balance the board design to get hips between front and back foot. As you can see on this picture my feet are pushing( nearly) both sides of the Redline TC front fin . GX-Q trailing behind with no effect except they are stabilizing my way.
About the very functional Vangard fat tail which is balancing square nose area , my idea that I demo is you dont need center fin on a SUP because for the most of those wide shape you cant really pivot on the back fin as you do on a 5'11" proned thruster surfboard.
Last point: square outline board get more volume for less width to a better whole stability of board , IMO Vangard type are a better way to do do ShortSUP shapes and getting the more benefits to go short and teeny.
