For vertical mounting surfaces. Marine-grade stainless steel.  Matches the hole patterns on the foot of the Wind Instrument, the Extension Bar, and the SailTimer Track Slider™.  Includes 2 special wing-nut hose clamps for stanchions (no tools required), and 4 pairs of stainless #8 machine screws (1/2-inch) and lock nuts.  $21.  Add to Cart | Checkout



Extension Bar

Rigid extension bar of 1/-4-inch thick (6.4 mm) aluminum. 16 inches long (406.4 mm), 1 inch wide (25.4 mm).  If your masthead is crowded, or you want cleaner air for the Wind Instrument, extend this in front of the mast and mainsail.  The hole pattern is the same as the foot of the Wind Instrument. 

This was originally stainless steel, but is now rigid 6061 aluminum to reduce your weight aloft.  If you don't need the full length, slide it back on the masthead so only part is extending out, to minimize any flexing if the boat is bouncing.  Since it is aluminum, a good option is to drill extra holes to tighten it down at the edge of your particular masthead.  Includes 4 pairs of stainless steel #8 machine screws (5/8-inch) and lock nuts.  $27.  Add to Cart | Checkout

Angled Extension Bar

If your masthead is crowded, or you want cleaner air for the Wind Instrument, extend this in front of the mast and mainsail.  1/8" thick (3.2 mm) aluminum. 16 inches long (406.4 mm), 1 inch (25.4 mm) on the horizontal surface and 3/4 inch (19 mm) on the vertical side. This angled version is lighter than the flat-bar version, because it is only half as thick.  But the angle is designed to prevent flexing even if your boat is bouncing. 

The 4-hole pattern is the same as the foot of the Wind Instrument. There are also 2 pairs of holes at each end on the side.  Because it is aluminum, additional holes can also be drilled if needed. Mount this over the top edge of your masthead, or against the side.  Includes 4 pairs of stainless steel #8 machine screws (5/8-inch) and lock nuts.  $36.  Add to Cart | Checkout

SailTimer Track Slider

How to install a masthead anemometer without lowering or climbing the mast

Because most masthead anemometers in the past have used wiring down the mast, there has never been an opportunity until now to develop a system for raising a masthead anemometer without climbing or lowering the mast.  Our system is the first (patent pending). With the previous version of our wireless anemometer, many sailors couldn't use it until they went to the trouble and cost of lowering or climbing the mast.  That's why we developed two new mounting options.  They may look simple, but actually took a lot of prototyping and testing since all masts are different.  So now you can get the SailTimer Wind Instrument™ and start using it right away, without waiting to install it in the off-season.

1. Cantilever Method (free):  The loop on the mounting rod is the simplest method for raising the Wind Instrument. Just attach an extra pennant or foresail halyard, and add a thin line (e.g. 4-mm diameter) through 1 or 2 holes in the foot.  It is amazingly simple:  just raise the Wind Instrument with the halyard, then pull it upright with the thin line on the foot of the mounting rod.  (We don't recommend using a pennant halyard on a spreader, because the Wind Instrument would be blocked by the sails on some tacks.)  If you don't have a spare halyard going up to the masthead or want to try a more solid attachment, then use the Track Slider below.

2. Track Slider Method:  Raise the Track Slider (in photo at left) to the top of the mainsail mast track.  The Base Plate (photo below) on the Track Slider is designed to sit flat against the mast underneath the rigid headboard at the top corner of the mainsail. The Base Plate is held in position by 2 slider cars in the mast track (which you provide, since there are different varieties on each different boat).  A cable tie holds the slider cars in the two notches on the Base Plate.

Add your own pulley block on the halyard shackle, and a new mainsail halyard on the block for pulling up the mainsail.  Further details are provided in the Owner's Manual (PDF, 4.7 MB).  This allows you to use the Wind Instrument until the mast is down or until you have taken a trip up the mast in the bosun's chair, to install the Wind Instrument on the masthead. 

The base plate takes up 1 inch vertically at the top of the mast track (flat against the mast, inside the mainsail halyard, and inside the headboard on the top corner of the mainsail, as in this photo).  It has been tested with lots of different mast and sail types, although there may be rare examples where it won't fit (and can be returned for a refund).

You'll need to put 2 shackles in the large holes in the base plate, with a size that fits whatever kind of clip (or knot) you have on the end of your halyard.

This is our most secure method of raising the Wind Instrument and holding it precisely in position at the masthead.  Attach a thin line diagonally from the Mounting Rod of the Wind Instrument to the shackle on the far side of the Base Plate (as shown in the photo at left).  This lets you tilt the Wind Instrument upright once it reaches the top of the mast. 

Marine-grade stainless steel. Fits a wide range of mainsail tracks and slider cars.  (Requires L-Bracket above, which is sold separately in case you already have it.)  Comes with the Base Plate, 2 cable ties, and 3 pairs of stainless #8 machine screws (1/2-inch) and lock nuts for attaching L-Bracket.  $14.  Add to Cart | Checkout


Extra Mounting Rod

Very handy if you want to leave one Mounting Rod securely mounted on your boat, but move the Wind Instrument home in the off-season or to another boat sometimes.  The Mounting Rod is rigid marine-grade stainless steel, and
is not bendy or whippy in spite of its height.   This is not like a shampoo bottle that is churned out by the millions each year;  this is custom-made for the Wind Instrument by hand.  It has a sturdy foot welded on, 4 screw holes, and the loop part-way up in case you need to raise it using the cantilever method (above) at some point.  The total height of the Wind Instrument on the Mounting Rod is 16.1 inches (41 cm). The Mounting Rod alone is 9 inches tall (22.8 cm).

Comes with a lock nut to tighten against the base of the Wind Instrument, and mounting hardware:  four 3/4-inch #8 stainless steel Phillips screws, and four pairs of stainless #8 machine screws (3/4-inch) & lock nuts. $22.91  Add to Cart | Checkout

Short Mounting Rod

The standard mounting rod is especially useful on boats with a large masthead, in case you want to raise it on a halyard at some point.  Then it is long enough to clear the masthead, and hold the Wind Instrument in clear air above the sail.  But if you don't want that height or have a small sailboat, the shorter version is a new option.  It is marine-grade stainless steel, and the same sturdy machinework as the standard Mounting Rod, although this shorter version is 9.7 cm tall in total (3.8 inches).

The Short Mounting Rod comes with a lock nut to tighten against the base of the Wind Instrument, and mounting hardware:  four 3/4-inch #8 stainless steel Phillips screws, and four pairs of stainless #8 machine screws (3/4-inch) & lock nuts. $22.91  Add to Cart | Checkout


Tripod Adapter

Put this on your tripod's standard 1/4-inch screw, then turn this into the M6 thread in the base of the Wind Instrument. One is included, but you can see two views at left.  Stainless steel.  $14.87  Add to Cart | Checkout

Replacement Wind Cups

If you happen to break your wind cups, it is easy to replace them. The cups have a tiny magnet in the flange at the base, and a brass jewel bearing in the top.  Installation instructions are here. 

$21.  Add to Cart | Checkout


Maintenance-free, quiet and high-performance.  This is the second version of the new axle design, with further improvements on the original 2016 AirGap axle. Machined to extreme levels of precision;  the tolerance is just 0.001 inch, for smooth cup rotation in even the lightest air movement. 

If you received your Wind Instrument before mid-January 2017, you could swap out your current axle for this upgrade.  The disassembly instructions are the same as when replacing wind cups.  Pull out the old axle, add a drop of adhesive (e.g. Marine Goop, super glue or 5200) on the base, and press-fit the new axle in.

Because of the precision involved, new wind cups (including jewel bearing and magnet) are checked for correct fit and come with the axle.   $26.  Add to Cart | Checkout
