I used to get cramps surfing so have done a bit of research into it - do you get them frequently or was it a one off?
peazz has given you the 'solution' if you suffer one - grab your toes. For the aftermath, massage and also ibuprofen is a useful drug to take, as its anti inflammatory and a pain reliever. BaNZ and gd6 have excellent suggestions on ways to minimise the risk.
Hydration particularly - often you cramp if you go out in the morning after waking up without drinking much and are still dehydrated from sleeping.
Magnesium and calcium are important but (in my view) if you only cramp while surfing, and not otherwise, then probably they arent needed - rather its a surfing specific cause rather than a general problem. On the other hand, if you do cramp while sleeping or have 'twitching' calf muscles when sitting or cramp during normal activity (pandarturo!), they might be worthwhile (most multi vitamins have both to some extent; and of course you can get specific supplements - but research as the types of Mg in pills varies and some arent as good as others). Obviously, Mg and Calcium occur in food! Leafy greens, sunflower seeds, nuts, dairy are all good.
That said, my view is that cramping while surfing is almost always caused by frequently pointing your toes, which shortens the calf muscles and causes them to cramp, particularly if you are dehydrated or its cold.
When do you point your toes? The obvious one is when paddling on the board, but the less obvious (and to my mind greater importance) is when you are sitting on the board in the line up. You let your toes dangle downwards, contracting the calf, and, in addition, the water is pushing past your toes causing a greater but often not noticeable contraction.
So my tip is to keep your toes at right angles to your ankle (ie normal foot position) as much as possible. Pointing your toes now and then is fine, but not for prolonged periods - and pay particular attention when sitting in the line up. Wiggle your feet around, point the toes ahead. Do some calf stretches while sitting. When paddling just bend your knees up.
