Showing 1 - 12 of 28 items. Once up on the foil, everything to windward of the leeward foil generates righting moment.

By doing away with the keel entirely, the design is now like nothing we have ever seen, particularly when it comes to how dynamic the power transition is between foiling and not foiling. The boats are designed to foil on the leeward foil, with the windward one raised to help increase righting moment: to help balance the boat. This means that when the AC75 is not foiling they are extremely tippy � much more so than most other boats of the same size.

Essentially, when the wind catches the sails, the boat wants to fall over as there is too much sail area for the amount of weight underneath the boat � something a lead keel usually counters on a yacht or keelboat.

Once the boat is up and on the foils, however, that all changes, as everything to windward of the single foil in the water balances the sails.

That means, the hull, the crew weight, the sail and rig weight, and the windward foil, all work to counter the sails. What all this means is that the boats go from being extremely tippy, to hugely powerful in just the few seconds it takes to get up on the foil. Then immediately [once they lift off] you have more stability than, well, take your pick, but certainly more righting moment than something like a Volvo 70 with a big canting keel. With lift created to windward by the foils, it is possible that the boats can sail diagonally to windward.

With the AC75 sailing on its foil, drag is dramatically reduced, vast amounts of power can be Large Scale Model Boat Kits 5000 generated and so speeds rapidly increase. But the foils can serve another purpose too. In order to be able to lift each foil out of the water, the foil arms must be able to be raised and lowered.

The further out the leeward foil arm is canted � essentially more raised � the closer the AC75 flies to surface and, crucially, the more righting moment is generated as the hull and rest of the boat gets further from the lifting surface of the foil.

There is another positive to this: as the lifting foil is angled, it produces lift to windward, which can force the boat more towards the wind than the angle it is sailing. As the foils work to provide stability to the boat when it is stationary both foils are dropped all the way down to stop it tipping over and to provide massive amounts of righting moment, they are incredibly heavy.

A pair of foil wings and flaps excluding the one-design foil arm which attaches them to the boat and lifts them up and down weigh kg. To put that into perspective, the entire boat itself with all equipment but without the crew weighs between kg and kg. It is partly due to this that you will see some teams with bulbs on their foils. If you decide to go for a skinny foil wing which would be low drag and so faster then there will not be enough volume to cram sufficient material in to make the foil weigh enough.

So some teams have decided to add a bulb in order to make it weigh enough but to also keep a less draggy, slimmer foil shape. As with everything on the AC75, the mainsail is a relatively new concept. It consists of two mainsails which are attached to both corners of a D-shaped mast tube. This has the effect of creating a profile similar to a wing. But there are drawbacks with a wing: they cannot be lowered if something goes wrong and require a significant amount of manpower and a crane to put it on or take it off a boat.

One reason a wing makes for such a powerful sail is that the shape can be manipulated from top to bottom fairly easily with the right controls. With the AC75 the designers wanted a sail that could have some of this manipulation, produce similar power but could also be dropped while out on the water. In addition to the usual sail controls, within the rules, the teams are allowed to develop systems for controlling the top 2m of the mainsail and the bottom 1.
