The problem I see with the EU wing is the back tube configuration.

It is curved in slightly and assume capped but still potentially an injury causing metal end tube that you could impact if your feet are taken out in waves ,go over off the back then slam back into the hull and tube end .

I would add a rounded extended piece to the stern .

this discussion may help too
