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.

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.
The L-&-R boat latch has been granted an International Patent. Persons or Organizations who are found to be in breach of this patent will be prosecuted to the full extent of the International patent laws.

[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.
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.

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.

Note:- Installation & Use of the L & R Products
The products need to be installed, and used, in accordance with the printed instructions on the packaging, printed inserts
and the information published on the website www.boatlatch.com. Release & Retrieve takes no responsibility for product
that is not installed and used within these guidelines.
The roller needs to stop the boat before it impacts the metal. More common with Towing eye boats.
Roller Supports - Length
If they are a bit short you can
use the Roller Extender

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

adjustment
A range of holes allows
adjustment - forward & back.

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).
You may not need to worry many of these these. Just depends on your present boat/trailer set-up.

Your decision here will involve the width and depth of the winch post,
