Modern cruising catamarans and trimarans have unique requirements in terms of sail design and construction. The reason for this stems from the stability provided by their wide beams, which in conjunction with their lack of heeling can make it difficult to determine when to reef sails. It is therefore not uncommon to see cruising multihulls carry full sail much longer than monohulls of the same size. This, in turn, means that the loads on multihull sails can often be double that of the sails aboard a comparable monohull.
