Years ago as a kid I saw a fantastic winter storm in crete (from land). The waves were crashing over the harbor wall (Chania, perhaps 12 feet?) and the inner harbor was rough enough for the fishermen to be removing their boats too (actually the waves were coming up the street in town).
A friend of mine just started keeping his 34ft boat there and the winter haulout and storage fees
were insanely cheap
, I think he quoted me about 1200 for the whole thing, approximately 6 months on the hard but could be a bit out there.
