It’s important to feel the helm; the boat should almost be steering herself by the time you are ready to engage the windvane. This is a nice feature because if you know the weather is rough, you can be hiding under the dodger and when you want to change your course, all you do is lean over and tug the line and you are done. All the other major brands at best can make only minor tuning, have no such adjustment capability or have a fixed axis, generally at 20 degrees. It is good practice to initially set the control lines equally. Offering a wealth of practical advice and a dynamic mix of in-depth boat, gear and equipment news, Sailing Today is written cover to cover by sailors, for sailors. In effect, it is the equivalent of the damping control found on most electronic autopilots. Upwind, the genoa and mizzen were usually enough to make 5 knots, and weather helm was nonexistent. In practice, this means a boat should often be slightly under-canvassed. Vertical axis vanes are still to be found but by far the majority of manufacturers have opted for the more sensitive and powerful inclined axis type.

Sometime around 1974, when I was in high school, I began buying it ...read more, B&G’s HALO series of radars now includes the HALO20+ and the HALO20, a pair of compact radomes expressly designed for use aboard smaller sailboats. Mia and I got married in Sweden only two weeks before our departure from Canada, and the voyage was to be our honeymoon, a delivery cruise to Scandinavia.

Experienced users often add such cords to the counterweights on other types of windvanes. Wind direction offshore tends to remain relatively constant over long periods, but there are always constant minor variations and gusts. Most sailors name their windvanes. The system is then engaged and the auxiliary rudder will take over steering the boat. Usually once you get the vane set up properly it will just stand tall and do it’s small tweaking from side to side so that is the kind of motion you should be looking for. We are compensated for referring traffic and business to Amazon and other companies linked to on this site. Straighten the Wake and Reducing Yaw The Hydrovane is the only brand that can adjust its’ sensitivity and the amount of power applied to control the timing and amount of steerage to course changes. The wind vane is tilted by the wind hitting it on one side to rotate the servo-pendulum (also called steering oar) that is deployed in the water. The easier it is for you, the easier it will be for your vane to steer. My wife, Mia Karlsson, and I (and our good friend Clint Wells) got our own taste of the windvane learning curve during a transatlantic passage last summer. Most servo-pendulum models steer using the ship’s rudder via control lines led to the ship’s wheel or tiller.

It even steered running under bare poles while we did foredeck work. For longer periods, the steering oar and wind vane with crescent are easily removed and stowed below. The steering oar or paddle in the Cape Horn unit is not an external rudder. Located just in front of the Cape Horn quadrant, inside the lazarette, the autopilot will be protected from spray and since it has a very light duty to perform, it’s life will be much longer. I will reveal other category of topics as they come. But if the wind shifts more drastically, let’s say 20°, then your course will also shift by 20° following the wind. After electronics, the best wind direction indicator is a wind vane or masthead fly, such as the Windex. 4.Trim the control lines – If the boat is not perfectly balanced under sail and requires some weather or lee helm, the length of the control lines can be adjusted to induce a certain rudder angle so that when the boat is on course, the steering oar is approximately vertical in the water and the magnitude of the correction is roughly equal on both sides. Keep an eye on the heading. No other system can do this. Wind vanes once found in the realm of single-handed sailing, self-steering gear has become universal on sailboats. On Arcturus, it took time to get acquainted with ours. All Rights Reserved. It is essential to have a safety line on the steering oar, to avoid losing it in the wake, the first time it breaks off. Any more than that, and it is time to make other adjustments. This line is best run down a lifeline so it’s reachable from the cockpit, but not in the way. For self-steering, this safety feature is no longer desirable. This force–which is considerable, especially at speed–is transferred via a steel stock in a horizontal tube mounted through the boat’s transom to a small steering quadrant mounted inside the boat. Sailing Today is the magazine for cruising sailors who love to sail the coast of Britain, across the Channel to northern Europe and beyond. Movement of the vane rotates the in-water servo oar (also called paddle or blade). Because of this, many sailors new to vanes get discouraged and abandon them. At the same time you are trimming your sails to this new point of sail. The mast should be tuned to render the helm as neutral as possible in medium wind.

The boat’s main rudder is usually fixed amidship (or angled slightly to offset a weather helm or lee helm) and a second, auxiliary rudder, directed by a wind vane, takes control of the steering. © 2020 Cruz Bay Publishing, Inc. an Active Interest Media company. The remote core setting line which is basically an endless loop going back to the unit and a bungee cord is attached to it to just keeps enough tension on it so that it is not going to skip off. Arcturus stayed within 10 degrees either side of our intended course when we had our vane working well. With today’s modern boats, most of them have spade rudders and it is more vulnerable to hitting something, damaged, shaft failure or something unexpected. However, a majority of sailors using the ratio knob’s middle setting and the vane partially sloped at about 20 degrees are all they need for their voyage.

A self-steering wind vane keeps the boat on a relative wind based course. In practice, we found this was often necessary, but you have to be careful. In fact, boat sales have been strong across the board as mariners have taken to the water in ...read more, In a year full of drama, the America’s Cup has been matching the news cycle step for step, supplying their own fair share of scandal. The boat is brought back to course by an auxiliary rudder or adjustment through the tiller to the main rudder. If the boat constantly wants to round up, don’t look to your windvane. It’s not as easy as pressing a button, but once you learn to use a windvane you’ll never get stuck hand-steering again. The servo-pendulum can also be controlled by a small electric autopilot connected to the forward end of the co-axial rod that steers the servo-pendulum. As the yacht comes back on course, the tilt of the wind vane decreases and the steering oar returns to vertical. Minor tweaking is fairly normal – to fall off or head up a few degrees. Then you replace it with the heavy weather 17 inch one that is made out of aluminum which is for heavy weather.

We often found that minor adjustments to the bungee damping control were most effective when dialing in a course on this point of sail. Set a balanced sail plan and trim the sails for that point of sail. 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.A vertical tube supports the air vane, which pivots on a horizontal axis at its base. 3.Fine tune the course adjustment, so that the boat maintains the precise compass course (or point of sail) required . In a circumstance where the wind suddenly backs, you will probably jump on the wheel, trim your sails and then adjust the vane to suit. So when you are motoring on light airs it actually will control the Hydrovane rudder and you get an autopilot. During our 2,000-mile voyage, Mia, Clint and I only hand-steered for fun. So if you did have problems with your steering, whether it is a quadrant failure, hydraulic failure or something happen to your main rudder. Once a boat is properly balanced, a vane should steer a straight course at least as well as most human helmsmen. Now the steering oar would be in an angle and as the boat sails forward, the flow of water presses against the steering oar, generating sufficient hydraulic force to aggressively swing the servo-pendulum up sideways. The goal should be to steer with your fingertips.
