DANG! No repiles.
I don't spose the questions are too difficult are they?
I would hate to put an end to someone's windsurfing career just because I might have asked some seemingly impossible questions.
Let me see now,.. Hmm,.. 1 seems pretty easy. So does 2.
And 3 is pretty straight forward too. Specially if it's your mast extension.
I spose question 4 could be a bit tricky if you're not following politics.
Or maybe it belongs to a kiter who wants to take up windsurfing.

Golly golly gosh! I would hate to be responsible for ending that dream.
Wellllllll, I know I said "No clues will be given" but I don't want to appear too harsh with this edict so,.. OK, a clue for the answer to question 4/.
It starts with K and it rhymes with Sevin.
There that should do it.
Just watch the repiles pour in now.
