    Sails provide drive force to a yacht through the mast, riggings and other sheets that are attached to the hull. Drive is defined as the force in the direction the yacht is travelling. However, except when sailing directly downwind, there will be a significant side force produced as Author: B.

Since our inception, North Sails has consistently delivered industry-changing advances in sailmaking technology, developing new materials to fit the needs of a wide range of boats and types of sailing.

These innovations have created an exclusive line of sail materials ranging from woven polyester, racing, and cruising laminates to 3Di composites.

Principles of Yacht Design was the first book for mnay years to examine every aspect of the process of yacht design and was welcomed with open arms by owners of boats small and large, practising designers, naval architecture students and the boatbuilding industry as a whole.

Now revised and expanded for its second edition to cover power boat design in more detail, it makes an even more /5(10). There are many with each having their own benefits and drawbacks. Before we look at the different kinds of sails let’s think a little about sail geometry.

Boat Speed with an Electric Trolling Motor. Most modern 12 volt trolling motors draw one amp of current for every pound of thrust. At an assumed electrical efficiency of 95%, the Motorguide T47 motor (rated at 47 pounds of thrust) will consume (47 * ) = watts and deliver *.

Here is an explanation of some of the maths behind sailing. Velocity Made Good ; Apparent Wind ; True Wind ; Velocity Made Good. The effectiveness of the proposed procedure has been tested by means of a case study related to the design of hull, appendages and sails of a 15” yacht subject to box-rules, designed and.

Discussion in 'Sailboats' started by the relationship between L and H is not exactly known because it is a complicated relationship between the geometry of the sails and the shape of the hull and keel.

(see various Chesapeake Sailing Yacht Symposia papers). Larsson and Eliasson's book gives the closest published. FIG. 5: A two-hulled yacht sailing at a heel angle Θ. The heeling torque M H (red) is due to the air acting on the sail and serves to tilt the yacht (increase Θ) and the righting torque M R (blue) is due to the geometry of the boat and M.

One of the best photos of Sailing Yacht A was shot back in as she headed out for her first set of sea trials. While Sailing Yacht A 's owner Andrey Melnichenko calls her a "sail-assisted motor yacht", she is regarded by many to become the world's largest sailing yacht.

Her formidable size of metres LOA — and generous volume — is. The first version of Sailcut was developed in and used by Robert Lainé for making the sails of his IOR 1/4 ton named "Flying Sheep III". Sailcut has been available on the web since and is used by many professional and amateur sail makers for offshore racing, cruising and recently for model yacht.

The results of the design analysis for a sailing yacht’s hull and sails are reported. The results were used to confirm the design of a 30ft long sloop, which was planned, designed, and built in.

The Aerodynamics of Sail. I have recently discovered an interesting series of technical articles put forward by WB-Sails of Finland and as many of these are related to the setting of sails for small sailboats, I thought you'd like to know about them.

ally a good form for light winds. Sails with maximum draft aft have good pointing ability, have a good top end speed capability and are recommend-ed for medium to heavy winds.

Draft stripes are often put on model yacht sails to assist in visualizing the shape in the sail when full of wind. Sail Construction Sails come in two general varieties. Kite rigs are wind-assisted propulsion systems for propelling a vehicle.

They differ from conventional sails in that they are flown from kite control lines, not supported by masts. Vehicles driven by kites include boats, buggies, and vehicles with snow and ice runners. They may be as simple as a person flying a kite while standing on a specialized skateboard, or be large, complex systems.Currently we’re working on a cool project with SimRad to create a training simulator for a gps device.

But to do that and to write the code and the statement of work for the programmer we had to be very clear about the math behind it all.25% discount valid only on Melges 24 sails purchased via the Quantum Sails online store and paid in full at the time of purchase.
