The most important thing to note is that the V3 “fits” in the anchor locker where the old one was. The V3 is about 1” longer. No modifications were needed to make it fit, except as noted below.
The wiring was identical. So, I did not replace any of the switches, relays, wiring, or anything electrical. I simply hooked up the new unit the same way as the old one was wired in.
The biggest challenge I wanted to fix was the elongated mounting holes (below) and to counter the torque / rotational forces that caused them.
Thanks to my friend George Menezes for his advice on fiberglass repair & construction.
1/8” thick, 1-1/2” angle aluminum stock was used to fashion a custom “Torque Bar” which would be mounted to the aft two mounting bolts beneath the deck. It would ensure both: the windlass would not be pulled up thru the deck, AND, more likely, it would increase the rotational mechanical advantage from 3-1/2” on this deck construction to 15” apart. Basically, it makes it impossible for this new windlass to rotate in-place.
Of course, working in tight spaces in this anchor locker made the whole project very challenging. The torque bar only made that part of this more difficult. However, my confidence in this new system makes the extra effort worth it!
Lewmar model V3 with 003 Gypsy (3/8” chain, 5/8” laid rope, or 3/4” 8-plait rope. 2248 pounds pull, 85 amps @ 12 VDC, (1000 watts). For 40-50 foot boats. Defender part # 013385 2000 Mainship 390.
Rocna 25kg – 55 pound Vulcan (anchor)
Rode: 200 feet of 3/8” G4 chain + 250 feet of 5/8” nylon laid rope.
The windlass should be “baby-ed” on your boat. Use a “snubber” as shown in the link above, to take the strain off the windlass when at anchor in any moderate wind or current.
Never use the windlass to “pull” your boat up to the anchor against a wind or current. Use the main engine(s) to position the bow above the anchor so the windlass only has the weight of the rode and the anchor-in-mud to lift.
Windlasses are expensive and they are a pain in the arse to repair or replace. So, Baby yours!
002 vs 003
Lewmar stamps their gypsy part number on the gypsy as shown. Again, our 3/8” G4 chain fits the 003 better (smoother) than our 002 ever did.
