The most recent design is the SAILOMAT 800/760/700 series, based on 40 years of self-steering design experiences, practical testing and manufacturing under the group leadership of Dr. When the boat veers off course, Windvane self-steering options fall into two categories, servo pendulum and auxiliary rudder. The boat: 50', 19 ton steel cutter, slightly modified full keel, skeg hung balanced rudder, with statly, even majestic performance. Other systems (servo pendulum) do not do as well in light air because in order to function the boat must be moving in the water, and there is all the other friction to overcome in the lines and main steering system. Join Date: Aug 2008. Trim tab, auxiliary rudder and servo pendulum systems are just a few. Mounting them to Usually if there is enough wind for the sails, there will be enough wind for the Hydrovane’s large vane. I'm still trying to find a good setup for running on any point of sail from aft qtr to dead downwind - dont have much problem getting reliable Mc Bride has extensive experience with Aries Wind Vanes having completed several South Atlantic crossings using what has become known as the “silent helmsman” – a servo-pendulum rudder mechanism, connected to a wind vane, that steers through the ship’s rudder through ropes connected to the tiller arm. A tillerpilot is a better choice for the Salish Sea/Georgia The Neptune Windvane works on a horizontal axis, servo-pendulum system, which is the most efficient form of self steering, using the vessel’s existing steering system to steer the boat, together with the Neptune’s 11 Servo-pendulum H vane. I basically built an early version of Walts vane, but after a total failure at making a servo pendulum, I totally changed it. Wind vane self steering is a mechanical device used on sailboats to maintain a desired course without the need for continuous manual adjustment. With this type of Self-steering Wind-vane, the rudder shaft moves sideways (swing), depending on the vanes signal and also on the position of the rudder. hess.

The casual observer might believe the long servo blade attached to the system is a rudder that directly steers the vessel. This more primitive steering system cannot keep your sailboat on a preset compass course; however, experienced sailors tend to agree that steering to a wind V vane only, on board a 5m/16ft Van de H vane only, QME windvane. Leave A Review bristol299bob 5. It replaced a much older servo pendulum gear and is just amazing in the band of wind and sea conditions it covers This is the Aires no. For me, the deciding factor in what windvane to buy for my own boat was my hydraulic steering, which doesn’t work well with a servo pendulum style windvane. While there are differences in their methods of transmission, the basic principle is the same. The state-of-the-art and innovative SAILOMAT 800 system represents the next generation in sailboat self-steering. On the whole the oar and vane are generally remarkably indifferent to boat size: in many cases the same system can steer anything from, say, 30 to 60 feet. What's new. The traditional Monitor H vane servo-pendulum system. 18-09-2015, 09:40 #7: s/v Beth. , broad reach) where the apparent wind direction varies wildly and the Monitor (or other A video demonstrating the concept of the Milling Swing Mount for Servo-Pendular Wind Wane self steering devices. The servo-pendulum system consists of a [sensor-vane] which transmits the change in the wind direction to the windvane rudder. This got my attention. If a small push rod autopilot (e. The relative motions of the wind vane system Our unique method for testing system stability (without even leaving the slip) See 5 different designs using the autopilot and a If you really want to build a wind vane system read on and eventually you will get to what he calls the "cook book" section where you will find his recommendations for various wind vane systems. While this is not practical for most un-ballasted small sailboats, a self steering device is an essential tool for the cruising sailor. The relative motions of the wind vane system Our unique method for testing system stability (without even leaving the slip) See 5 different designs using the autopilot and a A wind vane is a clever bit of engineering known as a servo-pendulum.

Servo pendulum wind vanes are expensive and often fragile largely due to gears, cogs and bushes The servo-pendulum wind vanes are the most widely proven principle for a windvane. 0) 1 reviews $980 USD. This principle offers a great sensitivity-strength balance and is lightweight. Its here the horizontal vane{its actually 25 to 30degrees] mechanical servo pendulum can convert ounces of effort from the vane into many pounds at the tiller. The transmission that rotates the vertical axis of the pendulum rudder also does this when the pendulum rudder swings I bought the vane used from a 40' Plus, mid 20,0000# boat. using the speed of the water to produce servo-energy. Overload protection with mechanical safety tube protects the vessel and the windvane. Also been playing with a larger head sail which shows some promise on those points of sail as well. Just a VERY strong servo pendulum wind vane system that can use an auto tiller to drive it. Servo-pendulum vanes can be broken down into three main components: the sensor vane, the pendulum rudder, and the linkages. The force required for controlling the servo is approximately 1/3 of the force required by an auxiliary rudder. 80 sailors with a special package and special price discount for their really neat servo pendulum wind vane self steering system. Forums. Brian Living aboard in Victoria Harbour. The purpose of a wind-vane self steering device is to allow the skipper to do something other than sitting at the helm. I have not noticed any difference in control on port or starboard tacks In the first Single-handed Transatlantic Race in 1960, "Jester" was fitted with a prototype Trim Tab Gear and advanced experiments were carried out, mainly with wind vanes of different sizes. The servo-forces here are usually Arcturus, our 1966 Allied Seabreeze yawl, has a Cape Horn servo-pendulum windvane, which operates on the same principle pioneered by Blondie Hasler back in the 1960s. Strong four-point mounting system. Pendulum Servo units that actually turns the rudder do get stronger as boat speed increases. Related Posts. The South Atlantic S 600 is both mechanical self steering for Unlike servo-pendulum steering systems, auxiliary-rudder wind vanes are entirely independent of all other aspects of the boat. This Windpilot auxiliary rudder The Hydrovane auxiliary rudder system is suitable for boats up to system: the H vane generates 11 m/36ft in length. I have been researching affordable alternatives for a few years now and considered different DIY solutions but this is the first one that speaks to me. Based on this input, the boat is The Hebridean wind vane servo pendulum self-steering (the boat in the picture is not a NIS) By the way, speaking of self-steering, I’m considering buying/building the Hebridean , or an own design based Essentially as the wind vane detects wind from either side, a transfer of that force presents itself to either an independent rudder or a servo-pendulum that redirects the boat’s course. Custom Spectra pendulum lines. Lightweight and easy to remove with 4 bolts. Starlight 35 (Sea Trial 1) Starlight 35 (Sea Trial 2) Halcyon 27 (Halcyon 27) Sadler 290 (Neptune Windvane fitted to Sadler 290) Hallberg-Rassy 48 (1) Hallberg-Rassy 48 (2) Bavarian 38 (Jesper Milling) The servo-pendulum with a vertical wind vane has become the standard for most commercially produced wind vane systems. Servo Pendulum Rudder. so many types, seems the servo pendulum is the most favoured. The servo rudder is controlled by a light airfoil / vane (horizontal axis type). The trick with making a servo-pendulum wind vane work well is to trim the sails for a balanced helm. With this type of Self steering Wind vane, the rudder shaft moves sideways (swing), depending on the vanes signal and also on the rudders position. One to one movement on pendulum lines. Plywood has several practical advantages as a material for H vanes. The South Atlantic servo pendulum wind-vane looks great, but I cannot afford that. Normalfornorfolk Member. the smaller wind pilot was too small and the larger wind pilot too expensive. The first is the Windpilot Pacific Plus II. Stainless steel, servo-pendulum. There are many different systems of windvane self-steering. This acts Stadt design more as a steering aid than a full selfsteering system. The distinctive features of this system were the aluminium windvane and the circular segment connecting the steering lines to the pendulum rudder which ensured uniform force transmission. The Hebridean has The Hasler vane is pretty much identical to the Aries and other servo pendulum vanes except the wind vane has a vertical pivot on the Hasler vice the horzontal pivot on the Aires, et al. The windvane was all Walt, made out of ABS plastic from the hardware store, stock aluminum from the hardware store and a blade out of 1/8 inch plywood. Windy is a strong, efficient, and reliable shipmate. (Wind vane All servo pendulum vanes obviously use the same principle, but do they preform the same? All reviews from all big makers I read are positive, and since people rarely have extensive experience with multiple makes of vanes, The windvane portion of this gear only aligns itself with the wind, Option 1: Aluminium Angle Mount. 00 star(s) (5. 4 Servo-pendulum gear Welcome to Mister Vee! - The lightest* and most sensitive windvane self steering, since 2006. Is an emergency rudder option really a neccesity? NORVANE Self-Steering Wind Vane. The enormous power leverage of the servo-pendulum design compared with other gears clearly reflects the considerable steering and servo forces it is able to generate. Remote course control Sailomat 601 servo pendulum self steering wind vane. 5m: M950 One of the subtle advantages of the servo pendulum system is that in the case of the boat slewing around suddenly due to a wind gust or wave, the sideways movement creates an automatic correction in the steering before the wind vane part itself can react. It is a servo-pendulum windvane . Senior Cruiser. it's a pendulum servo setup, following the usual concept, a bit like the Monitor or Aries but different. Does anyone know if servo pendulum wind vanes perform better than trim tab auxiliary rudders. Nick Franklin on the Isle of Wight designed the Aries, an elegant and robust piece of equipment, which is still made in Denmark. Stellan Knöös, both in Sweden and USA. Carlita is a light well mannered boat and requires finesse rather than brute force. This sideways motion is tranirnitted to the ti'ler or wheel by ropes and blocks. So I think I will try the second rudder with trim-tab. I was forced to go with an auxiliary rudder style vane, which gave the nice bonus feature of doubling as emergency steering in case, god forbid, I ever lose my rudder. The one in your list which is really different is the Hydrovane as it is not a servo-pendulum it is not as mechanically powerful, but has the advantage of not being linked to the tiller/wheel which is lashed. Whether you want a pendulum-type or an auxiliary rudder type wind vane really depends a lot on what kind Wind vanes can be used on almost all kinds of sailboats, even those running under engines, small or big sized, and on short and long-distance travels. This Windpilot Pacific V vane servo-pendulum system MKI (1969), is made of sstainless steel. Buck-boost vs Orion DC-DC. g. Save Share. The powerful vane and servo pendulum system took control of the boat to the extent that it could still steer a course with the sails Just to review quickly, a servo-pendulum system functions by employing a tilting wind vane to transmit changes in wind direction to a submerged servo blade via a push rod and a pair of bevel gears.

Might be just what somebody has been looking for :) Home. The servo-pendulum self steering consists of a [sensor-vane] which transmits the change in the wind direction to the windvane rudder. Avalon, Chertsey Meads, Surrey, KT16 8LN United Kingdom The servo-pendulum system is the “classic” windvane, with a small servo blade that looks like the windvane’s rudder in the water, and a larger windvane “paddle” Does anyone have any experience of using a wind vane directly coupled to the tiller without an auxiliary rudder/servo pendulum? I am planning to build a wind vane self steering system using plans from Bill Belchers book. Hydrovane drives its own auxiliary rudder direct from the wind power and does not use the force of passing water to amplify it. For a year or two I had looked at everything I In any case, modern servo-pendulum gears are sensitive enough that one vane is adequate for the whole range of wind strengths. The servo pendulum system makes use of the ship’s rudder through control lines guided to the ship’s tiller or wheel. Would work well with a wind vane wheel drive and could be dual purpose. Item Description Price; Aluminium Angle Mount: £ 166. Its wind vane are an innovative version of Marcel Gianoli’s 15-20 degrees offset ‘horizontal’ vane axle has featured on all servo-pendulum wind vanes since the ECA engineer’s angled axle solution first rendered the concept reliable. (Wind vane pivot on rudder stock in line with rudder pintles - 45 degrees - so they swing independently - Most of the wind vane self-steering sytems used today are based on the servo pendulum vane gear designed by Blondie Hasler in 1961. The deviation of this vane by the wind when the boat goes off course activates a series of mechanical gearing or levers to achieve the desired course correction. Technicals Manuals The Aries wind vane is suitable for a large variety of sailboats, with the Servo-Pendulum System your boat is steered by its own rudder, I can tell you that the servo-pendulem is far stronger than the hydro-vane especially when going down-wind in heavy seas. "Horizontal axis vanes and servo pendulum paddles are the most powerful self steering If you want a vane that can handle steering boats with higher steering forces relative to wind speed then amplification of the wind force via a servo pendulum is desirable. Allow for this in your budget. One other feature of the vane that I really appreciate is that it eases the load on the rudder and rudder bearings. The servo-forces here are usually enough to sail the main rudder of ships of up to 30 t (tons) safely. I like the redundancy of a spare rudder. The vane-to The world’s number one servo-pendulum windvane solution. The combined unit features the same construction details as the S 470.

Don’t just take our word for it, see what our happy customers have to say: I have been using my Neptune wind vane on a Prout Sirocco 26ft catamaran since 2011. of varying complexity, From simple windvanes to work a tiller directly, thru auxiliary rudder units, trim tabs, and two servo pendulum units. I have been looking on The self steering gear S 470 is a fast and efficient steering system. Monitor) and one that drives a secondary boat rudder (e. The Hebridean is a servo-pendulum wind vane. The Hebridean wind vane is a very affordable DIY servo pendulum self-steering gear that has a few (at least somewhat) unique details compared to the Windpilot Pacific Plus: Windpilot takes its Pacific-series servo-pendulum vanes one step further by using a servo-pendulum system to drive an auxiliary rudder. Believe it was more of a cost issue and motivation to be a vane builder instead of a I'm looking for a FLEMMING servo pendulum vane for a 33 foot sloop . Auto helm uses trim tab on the rudder to steer the boat. Fact: Modern systems work by increasing the wind vane’s sensitivity, The servo-pendulum wind vanes are the most widely proven principle for a windvane. Lightweight just 7 kilos!!!. Rather, the wind vane rotates the oar slightly on its axis (yellow arrow). The sail, or blade, of the windvane rudder certainly cannot have the strength to steer a large boat of many tons and in such cases those pilots that use a secondary rudder need a twin pilot Windy's self steering gear will make your sailing experience more enjoyable. In this particular system a Servo Blade ‘s’ is hung vertically over the stern with its shaft passing through a Servo Frame ‘f ‘ (see drawing on right). Instead, the main rudder is locked, Neptune Windvane. No unsightly "metal work" frame required on boat with transom-hung rudder. The servo-forces here are usually The Atoms servo-pendulum gear (System type 11) was produced in Nice, France, for many years and was very popular in its home waters.
