The BMW Oracle teams recent win of the Americas Cup-along with a flood of e-mail from multihull fans-has given us good reason to revisit the performance multihull alternative. In this reader-requested sequel to our Need For Speed monohull report (September 2009), we focus on design features that make multihulls fast and fun to sail, and examine why many feel that two or three hulls are better than one. It quickly becomes obvious that todays boats diverge sharply from the iconic Hobie Cat 16. To really get excited about performance in sailing catamarans and trimarans, lightweight, lean hulls and sizable sail area are a must. In this review we look at five terrific performance multihulls: The Hobie Getaway, Weta Trimaran, Windrider Rave, Corsair Dash 750, and Telstar.
When it comes to the pure love of sailing, its hard to beat a small, light efficient boat whose sole mission is to harness the wind. Designed in New Zealand, built in China, imported to the U.S. by Nor Banks Sailing of Duck, N.C., the 14-foot-6-inch, 220-pound Weta 4.4 trimaran with 158 square feet of sail was conceived in New Zealand by father-and-son team Roger and Chris Kitchen, and designed with collaborative help from a handful of experienced sailors. The challenge was creating a cost-effective boat with the strength-to-weight ratio needed for performance sailing. The boat uses carbon fiber on the framework, and on the mast and sprit while the light, stiff hull structure, daggerboard and rudder are built using less costly E-glass and Divinycell foam. The boomless mainsail, made by windsurfer sailmaker Gaastra, incorporates five full tubular battens that control draft and allow the mainsheet to be attached to a well-reinforced clew rather than a conventional boom. The high-tech Gaastra sail package, like the Harken hardware and carbon sprit and mast are all standards. The success of this pocket-sized trimaran is due in part to its triple threat sailplan of main, jib, and easy-handling, furling screacher. The screacher can add a virtual turbo boost. This 60- square-foot gennaker deploys like any roller furler but is trimmed via a single sheet led through both port and starboard leads. The ride is both exhilarating and responsive.
While we wouldn't consider the Tartan Ten to be one of the better-built racers, she doesn't have to be. Since she is primarily intended to race against her sisters, consistency between boats is perhaps more important than superior (and hence, more expensive) construction. The major construction criterion she must meet is to be sufficiently seaworthy to endure an occasional short offshore race. She meets this criterion, although, like too many production boats, she barely makes it.

Being a team of diehard do-it-yourselfers, we decided to try our own hand at devising a workable solution to defeating line chafe. After fiddling with canvas, old fire hose, and even messing around with some Kevlar, we settled on leather—an old riggers standby.
