Tail width should be measured from the centre of the back strap. The 1 foot off the tail or 300mm doesn't really apply to windsurf boards because your back foot is in a locked position unlike surfboards.
I don't look at boards with less length behind the back strap as being chopped off. Sure it started that way but boards like this are designed as a whole unit. The bottom shapes the rocker line the the outline and the geometry of fins ,mast track and straps all have to work together.
The longer style wave boards will generally be suited to powerful wave conditions because of their stability. The shorter style boards will be more suited to real world conditions but there is definitely a crossover between the two.
To say one is right and one is wrong is pretty close minded.
It also comes down to the style of the rider. I have a lot of guys that swear by their Nano's in solid conditions and I have other guys that swear by their Mako's for everyday conditions.
Just ride what works for you I say .
Doesn't the back strap adjust fore aft? Perhaps you mean the center of the holes in the board, that secure the strap.
just ride what works, yea baby.
to say one is right or wrong, is INDEED , close minded.
