Rig and Sails

The SIG45’s modern carbon rig was designed to be easily handled by a small crew, while retaining options for a racing crew to take advantage of the potential of the platform.

Simple reefs and sail changes

The combination of the rotating carbon wing mast and the large high aspect ACC/ORMA60 style fully battened mainsail provides both power and a highly efficient sail shape. With three deep reefs and lazyjacks, the yacht can be quickly and easily depowered.

The SIG45’s headsails comprise a self-tacking blade jib, staysail and storm jib, plus a gennaker and asymmetric spinnaker. There are no runners or adjustable backstays, keeping handling simple. A Code 0 for upwind work in light airs is available as an option.

The gennaker/reacher, jib, staysail and storm jib are all reefed using Karver single line furlers. This makes reefing and sail changes simple and easy. The asymmetric spinnaker is set and doused using a sock.

Excellent upwind performance

The SIG45’s headsails are flown from a single piece carbon bowsprit which extends forward from the main beam through the forward cross beam (which has a PBO martigale). The stiffness of this beam system helps to maintain luff tension in the jib. Luff tension and high aspect daggerboards are two of the keys to good upwind performance on a catamaran. Another advantage of the design is that the absence of waterstays dramatically reduced the amount of spray generated.
