Product Strength
A Relative Size Comparison
Note:- The products are for Launching & Retrieving NOT road travel - where winch straps/cables, rear straps, & safety
chains must be used.
Heavy Duty Snares
For very large boats we have produced a 'Heavy Duty' version.
(see note under "Strength Testing"). All made from marine grade stainless steel.
This is extremely robust and has the locating bolts at 100mm centres.
See details under “Safety” (button) on the left
L & R have established a reputation in Australia for an
extremely robust product despite the abuse that
boaties throw at it. But very occasionally we get some
wild man that manages to bend 10 mm stainless steel
plate. We have now added a brace that increases
strength in the direction (red arrows) shown by 220%
(tested by an independent certified testing lab.)
Front bolt must be
installed otherwise you will
void the warranty.

What Strength do you need for Your Boat ?
There is no exact answer, but we can get close enough for most purposes.
We will use the equivalent ‘counterpart’ - namely the L&R Boat Winch - as a
means of comparison.
The Winch - factors that effect winch strength are :-
(1)* Condition of the trailer - rollers or slides
(2)* Alignment of the rollers/slides
(3) Incline of the boat ramp - drastic effect capacity
A common rule of thumb is Winch Capacity = 1/2 boat weight
(formula) * This can be stretched to 1/3 boat weight
if the trailer is in excellent condition - see (1) & (2)
Tested strength (tensile) of New (2021 Towing eye snare = 5.6 Tonnes
Towing eye Snare-Heavy Duty = 5 Tonnes
Fibreglass Snare ..........…...... = 4.7 Tonnes
Fibreglass Snare-Heavy Duty = 7.5 Tonnes
Latch .......................…........... = 5.4 Tonnes
So in comparison with a winch, a boat weight of double these figures
could be viewed as the capacity.
