A very powerful sail for small multihulls such as the CLC SailRig. May be retrofitted to boats originally fitted with SailRig 40 or 55 rigs, but you must reinforce the mast step to manage the higher loads. You will also need to order the SailRig 70 "Mast Upgrade Package." Unlike the 40 and 55 rigs, this sail is raised and lowered with a halyard. The 70-square-foot sail includes 5/8" luff slides, battens, and TWO sets of reef points. (Only one row is shown in the diagram below.)
