Introducing the Mach2.3

The third major upgrade in the illustrious life of the Mach2 Moth has been completed and is now shipping.

We've been working hard to make the Mach2 faster, stronger and more reliable, whilst only adding 150 grams to the overall weight.

The M2.3 incorporates production improvements, lessons learned from the Sorrento World Championships and sailor feedback.

This is the best version yet of the our 7 times World Championship winning boat.

Tips For Beginners

How do I keep the boat on it's side?

Make sure that the sail is downwind with bow slightly into the wind, resting with the bow down, sail sheeted in to use the wind to hold it down. Always leave the trolley on for as long as possible and make sure it is always tied to the boat at the wing tramp fixing points. It is a good idea to put some protective padding on the wings to stop abrasion damage where they impact the ground.

How do I get into the boat once it's in the water?

Push or swim the boat out into water deep enough so that the foils won't touch the bottom when you right the boat. With the mast pointing downwind, climb on to the centreboard, and grasping the high side outer wing bar lean back until the boat starts the come up. You will be surprised at the sedate nature of the boat, the underwater wing acting as an effective damper. At the balance point, jump into the boat, avoiding standing on the flat side of the boat. If you do not manage to jump in in time do not worry, you will probably be swimming next to an upright boat so simply pin the windward wing into the water and swim into the boat, taking care to immediately grab the entire mainsheet system in one fist and giving it a good "pull" so you don't capsize to windward, or in very light wind, grab the foot strap on the opposite side to pull yourself across the boat to balance it.

How do I get on the foils for the first time?

Make sure you have the rudder in near full lifting angle – that means pin at the front. You need to check this each time you try to foil as you can unknowingly wind it back.

Turn on to a reach, keep the boat absolutely flat sideways and see if you can get the boat speed to 7 knots. You may need to hike out, and a GPS speedo is useful here to measure your speed. Do not sit too far back; Mach2's do not like an aggressive angle of attack on the foils so keep the boat level fore and aft. As the boat begins to lift it will quickly increase in speed. This means that the apparent wind will move forward and you will have to sheet the mainsail in harder in order to keep the boat upright and prevent a windward capsize. Make sure you have tell-tales on your sail. It is almost impossible to trim a moth sail correctly without them. Trim the sail to keep the boat upright but always look for a possibility to sheet out. Most people continuously over sheet as they learn foil and the sail spends most of the time stalled.

How do I use the tiller twist mechanism?

The tiller twist mechanism is used to control the pitch of the boat by changing the angle of attack of the rudder horizontal. With the rudder pin as far forward as it will go in the tiller slot - this will lift the transom. With the pin as far back as it will go in the tiller slot - this will lift the bow. To promote foiling the pin needs to be at the front of the slot so both foils are generating lift. You need to move the pin back in the slot if you find that you are too bow down whilst sailing. You can tell if this is case if the rudder horizontal is coming to near the surface. Equally you may need to move the pin back in the slot as you bear away at the weather mark to keep the bow up with. Think of it as a control, which is rarely static and needs regular adjustment. Remember clockwise rotation of the tiller extension on port tack will push the bow down but on starboard tack will pull it up. Many people mark on the boat which way is "down" so they don't have to think about it.

Do remember to check that the pin is near the front (bow down) when you try to get up on the foils.

How do I stop?

You can stop slowly by easing the mainsheet and reducing the power whilst at the same time moving into the middle of the boat until the boat drops of the foils, or you can stop quickly. If you are about to hit something or something is about to hit you, best to stop quickly. Either throw the boat into a capsize, or jump out! Both you and the boat will stop very quickly!
