That's what an offset mark is - and we already have them......
No, Darling marks are not just offset marks.The weather Darling mark is placed down wind and to the right (looking upwind) of the weather mark.The leeward darling is placed upwind and to the left of the leeward mark.You are not allowed to sail between the mark(called turning bouy) and darling mark.
Keep in mind Ice boats are going 40-70 M.P.H.,when you have a collision you are losing more then just gelcoat.
