In NJ during hurricane irene, probably like a 6 footer. Best I can remember, I havent really gotten worked, I dont paddle mavs, haha. But i just paddled out wrong, impact zone, out of breath, late duck dive,while not even catching my breath, tossed me around hard for a good 4 seconds, leash got tangled, I was really out of breath so started to thrash, not good, learn my lesson to not force a duck dive and take the breather.
