Towing eye Snare where roller doesn’t reach out far enough
Example - Here is an example showing Towing Eye (Aluminium) boats. In the first case ‘All is well’ ….. In the second  the roller does not reach out far enough to stop the boat. Here the more vertical post (with the same winch platform) allows the roller to sit up against the bow with the latch not too far forward. The solution is the Roller Extender allows a ‘quick fix’ without cutting, boring or welding.
Adjustment - Horizontal Adjustment 48 mm max. (4 hole positions) Vertical up/down 40 mm roller support arms Rear hole 121 mm (4”) Front hole 24 mm (1”) 50 mm roller support arms Rear Hole 104 mm (4.8”) Front hole 28 mm (1.1)

Our guide to the right parts that cope with a range of boats, that you can take to your trailer supplier for correct selection OR have produced to suit your needs. Click here to open. However it should be noted that the Fibreglass boat copes more easily with a winch post that is more laid back, as opposed to a aluminium boat with a towing eye where a more vertical post gets the roller in the right position.
Whilst there are quite a few weird trailers out there.  Too often  the boat and the trailer are not matched. We will try to show ways around typical issues. Here are some extremes. In some cases it just pays to swap the winch post and/or winch support.

       How do I correct the Wrong Snare to Latch Angle ? One of the most common problems for not getting the best results is having the wrong angle of the Snare to the Latch. This is where the bow is at an extreme angle and/or the trailer has an odd winch post angle.

(part of the ‘Wedge Kit’)
Example 1 The trailer requires that the latch be installed too far forward without support at the front of the latch. If you install it this way the latch is likely to bend at the point indicated, when under heavy load.

How to measure the Latch to Snare Angle ?

More Detail More Detail
How to change the Latch angle…. if it is not right [1]  Use the L & R ‘Wedge Kit’ which allows you to alter the angle in either direction by 14 0       See the Brochure “The ‘Wedge’ option” on website - under “Installation - detail version” [2] OR change the winch post or winch platform
Use a replacement from your local trailer supplier for one that has a more suitable angle.

The roller needs to stop the boat before it impacts the metal. More common with Towing eye boats.
Boat will not Latch when I drive the boat up to the Snare ?
How do I minimise boat movement on the Trailer whilst driving ?
Your boat should be securely held on the trailer - to restrict UP & DOWN movement, (even though the winch is tensioned up). The roller ‘’wedging’ the boat, as shown here. Don’t forget rear tie down straps to secure the rear of the boat if you suddenly have to brake whilst driving.
[a]  Is the trailer aligned properly to the centreline of the trailer ? Essentially the boat needs to travel down the centreline of the trailer, with proper support from each side. When this is right it will also glide far more easily on & off with less effort. The rollers/slides correctly positioned so the boat with minimum force is guided up the centre line of the trailer to meet the Latch. [b] Is the hitting the Snare at the right point shown above ? [c] Is the roller stopping the boat before the hook on the latch can engage ?

Finger Test 1
Adjusting the Latch relative to the Snare
With boat fully forward, touching the rubber roller/bumper, you should be able to put your finger (thumb width max.), between the latch and the snare. Important : On some trailers you may have to move the roller/bumper so as to let the boat come forward sufficiently.
The Latch should move aside to give a finger (thumb width nax.) spacing as shown in the photo. Note: the Snare, on the boat should be central - if it is not the boat may not be centrally aligned on the trailer.

Use a G-clamp to hold the Latch, under the winch plate to find the best location.
Roller Supports - Length If they are a bit short you can use the Roller Extender Roller Supports - Angle Short Roller supports may mean you cannot hold the boat back, and the Latch can hit the boat or the Snare hits the front of the Winch Support.  Solution - use the Roller Extender Latch - forward/Rear adjustment A range of holes allows adjustment - forward & back. Can be limited if the Winch Platform length is short. Use Latch Support   Bow Angle Typical shown here - but there are other extremes out there. This throws out the latch/Snare angle. See  &   to compensate.
Winch Post - Angle This is shown at an angle of 65 0  which for Fibreglass boats is normally OK. For Towing Eye (Aluminium) boats moving up to about 85 0  (or replace post) will usually sort out problems, OR use the …….. Roller Extender   to compensate. Winch Post - Forward/Back When installing - start with the winch Post back out of the way. When adjusting - move the Winch Post forward with the Roller/Wedge up against the bow. Winch Platform - Height Move up/down to get the roller/wedge to a point just above the Snare top. You want to ‘wedge’ the boat front so it cannot move up or down on the trailer. Winch Platform - Angle You can adjust this using   the Wedge Kit + 14 0   up or down. Winch Platform - Length Some Winch platforms are short. This robs you of adjustable length, and you may not be able to mount the front bolt on the Latch. You can extend this by using the Latch Support (part of the Wedge Kit).

Winch Platform is at 62 0 to the Winch Post. The easy solution is to cut and re-weld to a more suitable angle.
Winch Platform is re-welded at 80 0 . The thing to watch here is that there is enough room to mount the Base of the Latch,so that the front bolt has steel to mount to. Check in position before final weld

The angle of the winch post and Winch platform has quite a bearing on getting the roller to stop the boat at the right point. You want it to sit just above the towing eye, so that it ‘wedges’ the boat on the trailer… stopping it from jumping up and down with road travel…. and limits the boat so that the Latch engages nicely with the Snare.
