Lewmar Windlass Guide
| |
Yes, it is possible to convert any of the H2/3,
Concept / Ocean 1/2/3 and V2/3/4/5 range deck units to, or from a Gypsy
Capstan. The deck unit will have to be removed from the deck in order to
change the main drive shaft.
Yes, Lewmar make a range of different size gypsies
that will handle a wide range of good quality, calibrated chain. Check the
rope/chain chart in the windlass section of the catalogue or your windlass
manual for the correct rope/chain and gypsy match.
Yes, All of Lewmar’s High volume ranges of products
take rope and chain in the gypsy. The gypsy’s are design to take a range of
chains and ropes without the need to remove the rope or chain from the gypsy
during recovery. This means you can use a spliced rode effortlessly,
reducing both weight and cost of the rode. Check the rope/chain chart in the
windlass section of the catalogue or your windlass manual for the correct
rope/chain and gypsy match.
Lewmar recommends a premium quality, windlass
grade, medium lay, 3-strand nylon rope or a premium multi-plait nylon anchor
rode. There are many different rode applications based upon windlass, anchor
size, rode length and the anchor locker's depth and volume. For a list of
recommended rode choices for your Lewmar windlass please see
"Choosing an Anchor Rode"
Lewmar’s range of windlasses allows the drum to be
operated separately from the gypsy (independent warping). Once the primary
rode is secured, the clutch nut can be slackened off ½ a turn. Now when the
windlass is operated, only the drum will turn. This means that you can use
the drum when docking or for a secondary rope only rode.
Yes, all Lewmar windlasses have a manual free fall
function as standard. To free fall the anchor, you simply manually undo the
top nut half a turn. This releases the gypsy allowing it to free wheel. You
can control the speed or stop the descent by re-tightening the top nut. Some
of the larger windlasses with brake bands fitted work slightly differently.
Please consult the manual for free fall operation.
Most Lewmar windlasses have a manual recovery
option however the method varies across the product ranges. Some Lewmar
windlasses have built in manual recovery and others require an emergency
manual recovery kit. Please consult your windlass manual for clarification.
Yes. V700, V1/2/3/4 /5 & H2/3, come with magnet and
sensor fitted as standard. In most cases older Lewmar windlasses are
pre-drilled to take magnets and sensors. Lewmar have a range of chain
counters for use with our windlasses, please see
"Chain
counters"
It is not and easy job to fit an internal sensor to
the Pro-Series / Fish windlass but it is easy enough to fit an external
sensor up under the gypsy.
Yes. Lewmar have recently added a 3 button windlass
& 5 button windlass / thruster wireless remote to its range. These can be
used on any windlass / thruster that is operated via a solenoid. The
wireless remote is simply wired in parallel with the standard switch.
Yes. But you would have to purchase and fit a
solenoid & rocker switch. Some of the small Lewmar / Simpson & Lawrence
products are supplier without a solenoid. These units have the windlass
power switched directly through a high current toggle switch. The high
current toggle switch should be removed and replaced with a solenoid &
rocker switch. The wireless remote can then be wired to the solenoid in
parallel with the rocker switch. We have created a kit that includes a
solenoid (0052531), rocker switch (68000593) and instruction sheet. Kit part
number is 66000652
Yes. Lewmar recommends that when mooring, the rode
is attached to a suitable strong point. If using a rope / chain rode then
the rope should be tied off to a cleat or suitable strong point. If using a
chain only rode then a chain stopper should be used. If the load is left on
the windlass during mooring, shock loads could lead to damage of rode or the
windlass. With rope rodes left under load in the gypsy the rope can get
jammed into the gypsy causing damage to the stripper & rode when next
operated. There is also a risk that the clutch nut could come loose causing
the boat to slip its mooring. For our range of chain stoppers, please see
"Chain
stoppers"
Fall safe is a safety feature we have added to our
new products. It is used in two ways. When the anchor is stowed, Fall-safe
should be engaged to stop accidental deployment of the anchor. For
windlasses not fitted with Fall-safe, an anchor safety strap or similar
should be used. Fall-safe pawl should also be engaged during manual recovery
to act as a ratchet. |
In order to select the proper
windlass for your boat, three questions should be answered:
1. How long is my boat?
Use the selection guide to determine the general size of windlass to be used
for your boat length and displacement.
For example, if you have a 33ft/ 10m boat, a 600lb/ 270kg pull windlass
(Sprint 600) would typically be selected. Adjust the windlass size if
necessary, based on your answers to questions two and three below.
2. How long is the anchor rode you wish to use and
will it fit into your locker?
Begin by examining the depth of the anchor locker to determine the amount of
'fall' available. The fall is the vertical distance between the top of the
anchor locker and the top of the anchor rode when it is completely stored
inside the locker. This measurement is important in determining whether your
boat will be best suited for a vertical or horizontal
windlass.
Horizontal Windlass
|
The Horizontal windlass is a no-nonsense design widely used by
boaters requiring optimum performance from their anchoring system.
Boaters who frequently anchor, especially in deep water, require a no
hassle self-tailing system. The horizontal windlass offers the best
performance with small or unusual locker designs. As the anchor rode
enters the gypsy it makes a 90º turn and feeds directly into the anchor
locker. a minimum fall of 12"/ 30cm is recommended. |
Vertical Windlass
 |
Vertical windlasses provide aesthetic value and offer the added
security of the anchor rode making a 180º wrap around the gypsy. The
inherent design of the vertical windlass requires at least 12"/ 30cm of
fall.
This is to allow gravity to properly self-tail the anchor rode through a
90º vertical turn into the anchor locker. Additionally, nylon line is
lightweight and a short fall in a vertical windlass system might prevent
the rode from feeding properly into the locker |
3. How much pulling power should my windlass have?
Having selected the vertical or horizontal windlass sized for your boat
length and displacement, the correct windlass pulling power for your needs
must be determined using the following formula:
First determine the total weight of the ground tackle which comprises the
anchor and rode.
For example;
| |
The weight of your anchor |
= 22lb/ 10kg |
| |
The weight of your anchor rode comprises |
|
| |
15ft/ 4.58m of chain (at 0.74lb/ft or 1.09kg/m) |
= 11lb/ 5kg |
| |
200ft/ 61m of rope (at 0.06lb/ft or 0.09kg/m) |
= 12lb/ 5.5kg |
| |
Total weight of ground tackle |
= 45lb/ 20.5kg |
Second, take the total weight of the ground tackle
and multiply by a factor of three to arrive at the required windlass pulling
strength. The factor of three covers the effects of windage and the speed of
tidal current and includes a safety margin for unknown circumstances.
In our example the required windlass pulling strength is 135lb/ 61.5kg (3 x
45lb/ 20.5kg).
Safety guidelines suggest that the required windlass pulling strength must
not exceed 1/3 of the maximum pull capacity of the windlass. Therefore, our
selection of a 600lbs/ 270kg pull windlass is correct as the 135lb/ 61.5kg
required pulling strength is well below 1/3 the maximum windlass pull
capacity.
Working Load
In a typical anchor recovery situation, the windlass will pass through a
number of phases of operation as the boat approaches the anchor and
finally breaks it out of the seabed. The load and speed will vary at
each phase. For any anchor recovery, the windlass will operate longest
in the 'working load' phase and it will experience a significant peak in
load during anchor breakout.

Electrical Circuit Protection
Any installation of electric powered windlasses must be protected with a
circuit breaker. This ensures complete protection of the electric motor
and installation cables if the windlass is overloaded.
Circuit breakers are normally rated on a 'continuous' basis. This is the
load in Amps, under which they will retain electrical contact for an
indefinite period. For example, a 70Amp circuit breaker will not trip
unless the continuous current exceeds this figure. However, the maximum
tolerated current draw may be as much as 250 Amps, but only for a short
period of time. All our windlasses carry a recommendation on circuit
breaker rating based on continuous operation.
Remember that motoring up to the anchor whilst using the windlass to
retrieve the anchor rode and using the boat to "break out the anchor" is
the proper anchor recovery procedure. Using the windlass to haul the
boat to the anchor is not recommended and will result in damage to the
windlass and motor.
Safety At Anchor
Windlasses are not designed to hold high loads while a boat is at
anchor. When the windlass is not is use and the boat is at anchor, the
anchor rode should be secured using a chain stopper or attached to a
load bearing point such as a cleat.
