One of our first projects was installing a new anchor windlass and replacing the old rusted anchor chain. We chose a Lighthouse Manufacturing model 1501 with two chain gypsies and one rope drum, and replaced the 3/8" BBB chain with 5/16" G4 [High-test] chain to gain strength while loosing weight.Windlass: Condition resulting from successful treatment in a windward.
Windward: Section of hospital for boaters with chronic gas problems.

We can now retrieve two anchors simultaneously if we ever need to... Sweet.

Note: Our bow configuration changed in Jan-2017 with a new best bower...

Design Note: Windlasses require at least a 90° wrap of the chain around the chain gypsy to operate correctly under load. [i.e., 1/4 of a turn minimum... more is better...]
Less than 90° can cause the chain to hop on the gypsy under load. [So can too much twist in the chain. This is presuming perfectly matched ISO chain and gypsy.]
Vertical windlasses have no problem with a chain wrap exceeding 90°; sometimes that can be a challenge with a horizontal windlass.
To improve the chain lead-in angle one can either raise the windlass or lower the chain as demonstrated in the following photos:

Lighthouse Windlass Model 1501 Features: [From the manufacturer's website]
- MULTIPLE OPERATIONAL CAPABILITIES:
Port and Starboard chain retrieval and payout can be independently operated, or can be simultaneously operated in opposite directions (paying out one while retrieving another) also allows rope wildcats to be operated either independent of chain operations, or in conjunction with chain operations.
- MANUAL BACK-UP:
Fast rewind socket port and starboard, or an amazing 10,200 lbs. On 2nd speed, with only 35 lbs. Exerted on a 10" winch handle, in kedging socket located on top of winch. [This is a beast of a manual kedge...] Both manual modes are used in conjunction with a standard winch handle. Rope wildcat allows rapid rope retrieval and can be tailed, even under power.
- MOTOR DRIVE:
Continuous duty linear power unit (no field windings to burn out). No external grounding required (unit cannot induce electrolysis). No overload protector required for motor. Reversing is optional without changing the motor. 12v, 24v, 32v, 110/220 VAC, and Hydraulic power are available.
All stainless steel type 316L construction, sealed case lifetime lithium lubrication, mounted to built-in base plate. Comes with chain pipes and cast urethane deck seal. [We clamped 2" ID exhaust hose to both SS chain pipes below deck to direct and quiet the chain.]
Required deck space for mounting plate is L10" X W11.6", bowsprit mounts L12" X W4". Mounts with (6) ½" bolts. Motor mounts under deck and requires only 2" hole. Optional [SS] backing plates are available from the factory. [We had one custom made for a very reasonable price.]
- GYPSY and WILDCAT:
Standard cast bronze chromed gypsy and stainless steel wildcat port and starboard. ¼" through 7/16" BBB, PC, or System 40 HT are standard, others available on request.
- POWER CONSUMPTION:
- 12v: free run=8amps/rated pull=80amps
- 24v: free run=4amps/rated pull=40amps
Continuous line pull at 12v - 32v 1000 lbs. @ 37 fpm.
Maximum, depends on available amperage from power supply.
Height: 8" (203.2mm)
Length: 9.5" (241.3mm)
Width: 24" (609.60mm) [This is for the dual gypsy, dual rope drum model.]
Weight 110 lbs. (50.00 Kg)
Depth: From top of deck: 14.5" (368.3mm). Unit will accept up to 4.5" (114.3mm) deck thickness as standard. Optional extension housings to 48"
