Achieve Your Potential in Competition IOM Sailing

Vickers RC Sailing

Producer of the V11 Competition International One Metre Design by Ian Vickers.

Our workshop opened in 2014 with the V8 IOM. Since then we have produced hundreds of hand crafted IOM yachts in the Vickers design range. Yachts that have helped IOM competitors around the world achieve their potential and exceed expectations in competition.

We are currently offering the V11, the innovative design that finished 3rd at the 2019 World Championships in Port Alegre, Brazil.

When our clients return, they know they are tapping in to smart, competitive technology in IOM design and build. Stiff, Lightweight boats, that are Easily Assembled, Fast and Forgiving to sail. Join the fun!

Improve your results at the club and the regatta, with the fast and forgiving V11 from Vickers RC Sailing

Set Up and Sail

The V11 detailing is simple but effective. In conjunction with the V11 Set Up Guide, assembly is straight forward, and vital tuning information assists you to quickly understand and master your V11's potential

Vickers RC Sailing build processes are well refined and thought out.

Our boats are light, stiff and clever,  keeping to a simple and effective philosophy around detailing

The V11 design is a hull, foils and bulb package to compliment the full range of conditions experienced in RC Sailing. The hull design has full volume forward and features the familiar chines and tumblehome of the modern IOM for reduced weight and windage, as well as good tracking characteristics. The V11 features our peaked style foredeck for efficient water shedding when buried downwind and a geometrically strong shape for the forestay and mast ram areas.

Foils are slippery and strategically positioned with the rig to balance the yacht. The V11s forgiving balance through the wind range, allows the skipper to focus on the race at hand, and not rely on micro steering to maintain a consistent VMG.

The rig sits solid on its deck stepped mast step, complimented at deck level with an encapsulating mast gate arrangement over the mast ram. The rudder tube is rigidly supported inside the moulded servo tray. 

Hull construction is from E-Glass Fibreglass Cloth and High Grade Epoxy Resin.

The foils are Carbon Fibre Layup with High Grade Epoxy Resin.

Paint system is a 2 pot Urethane and the boat is thoroughly post cured before finishing.

The V11 Features-

Plastic main hatch access. 

Ready to accept RMG Winch and Standard sized Rudder Servo

Bow Bumper attached.

Hardware is Bantock including an adjustable mast ram, adjustable mainsheet post and tiller arm.

All necessary fittings attached for standing and running rigging.

The V11 comes out of our workshop in Beach Haven, Auckland New Zealand and is ready to accept rigs and electrics.

We also make sails that can be added to the order, or ordered separately.

So hit the enquiry button to discuss delivery times and options.

We are ready to help.

Essential to success in sailing comes down to the  Rig and how it is set up and tuned. The V11 comes with a Set Up Guide that covers all the expert information needed to set up like the guns. It specifies the hardware, construction and tuning information to get your rig and sails set up and sailing near optimum straight off the bat, so you can enjoy your racing and punch above your weight.

Include Sets of sails from Vickers RC Sailing and enhance the experience.

Vickers Rc Sailing is back taking orders again for the V11

We look forward to hearing from you

IOM radio control yacht sail tuning

We are constantly working and thinking how we can improve IOM radio control yacht sail tuning as big speed gains can me made from a efficient rig.

Some basic principles that we work with.

• Fore stay tension  It is very important that the fore stay does not sag as this results in the jib becoming too full and this happens when the breeze is up and right at the time when you don’t need it ! Pre bend in the mast will fix this. A mast with no pre bend will need  the side stay chainplate base  about 20 mm aft of mast step with a lot of tension on the rigging to keep fore stay tight without bending the top of the mast too much.
• Mast bend for and aft   With a perfect sail and the right wind conditions the mast will be best straight once the pre bend is pulled out with the back stay. However, not all sails are perfect and the wind is always changing in wind strength ! When rigging the boat I always first set up the mast so it is straight. Then I will set up the sail with the right amount of twist for the given conditions .  I then will look at the fullness and shape of the sail and put more back stay on or less, alter the spreader angle and change the mast ram to get the desired shape in the sail . After doing that often the mast will not be straight at all and sometimes it may have a S bend  however I see the result of a good sail shape is most  important. We use a lot of side stay tension and adjustable spreaders to enable us to easily adjust the sail shape.
• Mast bend sideways Usually when the mast bends a lot sideways the boat does not point as well. That is one reason we use the mast gate in our boats so we know it does not have side bend down low . The spreaders also control sideways bend. If the spreaders are too long it can cause the mast to bend to leeward in the middle and this can result in the jib slot being closed that is not efficient. Some people have windward side bend down low to open the jib slot but I dont think this helps the main sail setting. If excessive pre bend is used the mast is very difficult to control sideways with it always trying to flick off one way or the other. If you can make the mast flick off sideways at the very top  this can be a good thing as it can free the main leach in the puffs
• Mast rake  This is all about balance . We aim for a neutral helm  when the boat is sailing on the wind with the controls are  let go and almost lea helm when the boat is flat in light conditions.(when the boat leans it naturally wants to round up from the hull shape) The further forward the mast is raked results in more lea helm and the further aft the mast is raked results in more windward helm. Twist in the sails has the same affect. The more twist in the main the more lea helm and the tighter leach in the main the more windward helm.Opposite with the jib. More twist in the jib results in windward helm  and the less twist in the jib results in lea helm. We set our boats up with a lot of rake as we like to have a lot of twist in the main
• Jib sheeting   We have   found best results when the mainsail is central the distance between the center of the jib boom and the center of the mast is between 55mm and 65mm. Downwind when the main boom hits the stay the jib should never goes past 90 deg to the interline and back to 75 deg when it is nose diving conditions
• Main sheeting We have a high button on our radio so if we want to point f0r whatever reason we press this and it brings the main sail into the center line . Normal sailing with all rigs the main is off the post between 8-10mm
• Vang   This will totally control your twist upwind and down. The  variable geometry vang  is very good to enable the right amount of twist down wind . We have found the less twist down wind is fast unless the boom hits the water too much
• Jib up-haul  The amount of tension on this depends on how far forward the pivot point is and how much tension is on your back stay . The more pre bend on a mast results in more tension on the up haul. Ideally the jib will twist off when a gust hits and this will not happen if too much tension is on the up haul
• Main boom height  This needs to be low as possible without hitting the water. This is all about less sideways force in the breeze
• Jib boom height   Again this needs to be low as possible without hitting the water  A boat will nosedive twice as quickly when the goose winged jib hits the water. We have found that when the jib is set as close to the deck as possible the wind is channeled through the slot more with small increase of boatspeed because of the shape of the bow and forward deck
• Counter weight   15 gram is best for A rig and 20 gram for B rig .Usually best if when the boat is held tipped on its side that the end of the boom stays level. Also if the weight is higher it seems to be more responsive and helps with getting the jib boom out sooner
• Rigs quick to change If sailing in regattas it is very important to be able to change rigs quickly. Many regattas have been lost because a fellow competitor saw the breeze and swapped rigs while the rest were napping. This means having rig boxes that are set up carefully so rigs can be stored in tune and only requires attaching the rigging screws and sheets to quickly get under way. Always check mast bend and sail shape before sending boat out.
