J Class Hulls - Setting up and tuning the J class.

Full sized racing yacht crews use a combination of sheet tension, vang tension and traveler adjustments to optimize mainsail trim and twist. They can shift gears, for acceleration, for top end speed, and power up or depower the main in response to wind gusts. On model yachts, trips to shore are usually necessary to make adjustments.

In the IOM class, a single line usually controls both the main and the jib. Two sheets are attached to this line, one for the main and one for the jib, running through a fairlead to an attachment point on the boom. Typically, the main boom sheeting angle on the beat will be about 5 degrees, while for the jib it will be around 15 degrees.

The addition of a jib club allowed the jib shape to be controlled. Like the main sail the foot of the jib will fly up is some type of vang is not in place. Typically a swivel is placed along the forward end of the jib boom and clipped to a deck fitting (aka jib rack). Look at the jib as a triangle. Width: 125 mm. Rig Height: 1050 mm.

The model yacht works exactly like a full-size yacht with the slot effect, and yes the jib and main are adjusted proportionally to achieve the same lift from the sail shape to propel the boat forward.... the development and availability of radio control heralded a major change in model yacht sailing and racing.... Big yachts have autopilots. Next, sight the top of the main sail, it should lie out 1 3/4 inches from the backstay line. You can now adjust the jib so that it too follows the main sail's twist while keeping the slot between the two sails the same all the way along the length. Another guide to check the main sail's twist is to attach a telltale on the back of the top batten. The A Rig jib connects to a ring on a line led through a fairlead installed in the tube, and the B & C Rig attach to wires in the slot in the deck using ball raced jib boom swivels. To finish glueing and filling around the bulkhead and deck area, I coloured the resin with matching gelcoat pigment (add pigment by about 5% of total volume of mix.

When an external flap is added it creates a slot. The Slot allows some air to go from the windward side to the lee ward side. This air slipping through helps the boundary layer to not separate. This allows the slotted wing to perform well in high lift situations. I make my main wing and flap elements 50 /50. Some go 60/40. The addition of a jib club allowed the jib shape to be controlled.

The shrouds are fixed at the height of the jib stay. There are two different solutions: First, a commercial fitting riveted to the mast which looks good but cannot be changed after installation. Second, use homemade steel wire hooks inserted in holes you drill into the mast.

Free movement of the main and jib sheets along the deck. The scale detail kit pieces were not mounted on the deck for this reason. The jib rack was made from the same brass section as the chainplates, and is also 2.5" long. A mast step was fabricated out of 1/8" aluminum and was drilled out to accept the keel retaining bolt.

Radio Control of Twist - See the Model Yachting doc written by Reichard for "sheet vanging" information. Sheet vanging is written up in Optimizing, but Reichard 's version is more easily understood and applied. It is posted in this thread directly above. Sheeting angles upwind - Jib and Main Boom Sheeting Angles. Storm jib - a smaller jib meant for stormy conditions; Trysail - This is a smaller front-and-aft sail for heavy weather; Mainsail. The mainsail is the principal sail on a boat. It's generally set aft of the mainmast. Working together with the jib, the mainsail is designed to create the lift that drives the sailboat windward. Varies by country. There was no significant one design racing anywhere during the free sailing era. When the American Model Yachting Association was formed to promote radio sailing as a successor to the old Model Yacht Racing Association of America (whose members, amazingly, were often hostile to expansion of the sport), one design classes rose in popularity and now dominate in numbers.
