Not much talk re unlimited boards anymore , has this side of sup died?

Yesterday a good friend of mine let me borrow his new LE boards so I could paddle them and take some pics..

I first took some pics of both boards together and I then took each board for a paddle and took more pics of each one on the water..

This is my first lot of pics.. These boards are sweet.. Very sweet..

I've been thinking of tail design or boards and looking at yachts and wondering if SUP are more like boat design as apposed to surfboards.

For a Race/Tour style board. Is it best to have more volume at the tail or less, Is it about reducing the wave drag and therefor wouldn't a pin tail be better?

Looking at some designs they seem to almost narrow pintails, (Bark) and others are quite wide.

What are the advantages? in terms of paddling?

Like some yachts they seem to be really wide at the stern, (good for reaching and down wind) but maybe don't perform as well heading into the waves.

Anybody from a yachting background, hull design?

Thanks in advance
