  • The Manta 46 Evolution of the “Ultimate Offshore Cruising Catamaran”
    The Manta 46 Evolution of the “Ultimate offshore cruising catamaran” Concept: Pat Reischmann www.hytechmarine.com Design: Cortland Steck N.A. www.steckyachtdesign.com Pat Reischmann and Cortland Steck N.A. have collaborated to create the new Manta 46 as the next generation design for the original concept of the Manta 38-42 sailing catamaran. That original concept focused on the direct needs and requirements of the extended or full time live aboard cruising couple. Starting in 1994 the original Manta design had been very successful in fulfilling those needs with 127 built by production end in 2008, and today still enjoys a loyal following with strong brand recognition. As the catamaran market has expanded in recent years, more designs have been developed for either the charter business, or the very exclusive high performance end. Consequently there exists an ever larger gap in production designs for the extended or full time live aboard cruiser who wants to venture offshore. Design Concept With advancements in design and technology, particularly in communication and navigational electronics, extended or full time live aboard cruisers are expanding their horizons. Consequently they are looking for higher cruising speeds under power and sail, with more comfort, safety, and livability in offshore conditions. To meet this requirement the new design includes the following features: 1. High bridge deck clearance to accommodate larger seas without pounding. 2. Hull fineness, underwater foils, and a displacement, that will offer an “easy” level of higher performance under sail and power than the production charter catamaran designs. 3. Livable accommodation plan with the focus on one couple with occasional guests.

  • Optimist Trimming Notes
    OPTIMIST TRIMMING NOTES Toni Tió Velas, S.A. QSDGroup Manel Ventura i Campeny, 12 08339 Vilassar de Dalt (Spain) Telf +34-93-7533411 Fax +34-93-7533900 E-mail:[email protected] Toni Tió Velas, S.A. QSDGroup OPTIMIST TRIMMING NOTES The most important items, in terms of speed, for any sailing vessel, are the shape and properties of the appendages, since it moves due to a combination of aerodynamic and hydrodynamic forces onto these appendages. Therefore, good care must be taken on sails, dagger board and rudder blade. Dagger board and rudder blade are simple when thinking about an Optimist dinghy, since their construction material and shape are very restricted by the Class Rules, they must be stiff and the edges well shaped. But it is much more complicated when talking about SAILS. Sail material is also well restricted by the Class Rules, but an important allowance in the sail shape lets the designer improve the product in terms of speed, pointing angle, power, weight of the sailor and so on. Moreover, the Optimist sailor can trim the sail in order to change the factors above depending on the weather conditions. 1. DESIRED SHAPE Generally, when sailing upwind, leech tension and luff camber are the main items to consider, combining speed with tacking angle. It is well known that it is not possible to have all the needed properties of a sail at the same time, so it is important that we know when to look for a particular characteristic depending on die sea and wind conditions. A lot could be’ written about the leech, the luff and their relationship with mast bending and sail fullness, but this pretends to be an easy to read issue and the lack of trimming controls of Optimist Dinghies would make it even more complicated.

  • Leisure Furl Gybe Control.Pm6
    IT IS THE OBLIGATION OF EVERY SKIPPER TO PREVENT UNSAFE AND DESTRUCTIVE BOOM MOVEMENT BY ENSURING THAT THE BOOM IS Accidental Gybes RIGGED FOR GYBE CONTROL Rigging preventers and boom brake type systems Accidental gybes happen in all conditions, even in light air a momentary lack of concentration can result in an accidental gybe. All booms should have some sort of control rigged when sailing deep off the wind. Again, even in light air conditions a boom can develope dangerous and destructive inertia when allowed to gybe freely. In-boom furling systems are heavier than standard booms, and it is more important to control their freedom of movement. Preventer systems and boom brake type systems must be rigged to suit the layout of the boat, and all boats are different. Likewise the choice of which type of control system to use is an individual decision with varied opinions between experienced sailors. A preventer is rigged from the bale on the bottom of the boom, and led forward to the toe rail. A snatch block can lead the line aft to a winch. If your boom can dip into the water at any time, a shock absorber must be included. Shockle is a product which can be rigged into the preventer line to allow the boom to have some freedom of movement. If the boat cannot be steered back to the original gybe, a rigged preventer must be released after the gybe to get the boat controlled. CONSULT WITH YOUR RIGGER FOR THE BEST METHOD TO CONTROL YOUR BOOM Shockle IT’S YOUR RESPONSIBILITY shock absorber AND PRUDENT SEAMANSHIP www.shockles.com Another popular approach is to rig a boom brake type system which allows the travel of the boom at a slow rate during the gybe.

  • The Bluewater 450
    boat test bluewater 450 When the sum is greater than the parts — the Bluewater 450 IN THIS REVIEW we take a look at a blue AY editor, Barry Henson, takes water cruising boat, a boat that is de- signed from the keel up to take you down the Bluewater 450 for a test sail the coast or across oceans with equal degrees of confidence—it’s the Bluewa- on Moreton Bay and discovers ter 450—and it’s made in Australia by Bluewater Yachts. a world-class Australian cruiser. The challenge with reviewing a semi- custom boat is that certain aspects of the design are determined by the client, others by the builder or designer. Try- ing to identify the source of features is not as easy as it sounds, so this review is of Charlie’s Dream, an execution of the Bluewater 450, rather than of the Blue- water 450 as a concept. The Design brief I always review each boat against crite- ria relevant for the designed use. Unfor- tunately, many boat builders try to por- tray their boat as all things to all people, i.e. ‘this boat will take your family safely around the world and put you first in your IRC division’. Hmmm. Will it make coffee and pay my bills as well? Thankfully, the Bluewater 450’s de- sign brief is fairly straightforward; it’s ‘designed to provide its owners with an excellent offshore cruiser that could oc- casionally race around the buoys’. Still someone with an absolute passion for trying to hedge our bets a little, but his work.
