Rickk's Windlass Install

[seabob4]

Guys,
You know I buy all my cables from boatersland.com, have been for years, they have the best prices (IMHO) and excellent service, never had a problem with them.

It's not easy to find wire on their site - you'd think they would have it under electrical.
I'm about to put a windlass on the 230 and need #8 or #6 - guess they don't have that, huh?

Rick, check with Greg's, I don't buy wire from boatersland, don't really think it's up their alley...http://gregsmarinewiresupply.com/Zen/in ... 997284983b

You may want to think about 4GA for a windlass...

[RickK]

Lewmars docs says 8ga but I figured I'd beef it up a little to 6ga.

How about this site? http://www.pacergroup.net/Categories17.aspx?Id=2_Conductor_DC_Boat_Cable

[RickK]

When you measure from the battery to the windlass  you need  + and - obviously. The docs say to 33ft you can use 8 ga - 6ga to 53ft.
Do you think those 6ga pair wires from pacer would work?  They say that the total wire length is from the battery to the device and back to the battery.  I figure I would need 50 feet.  That's pushing the 6 ga, so you're probably right.

What current(amps) does it draw?

[seabob4]

Rick,
Your round trip (battery aft) is probably going to be in the 50' range, so you will be good with 6GA.  But price the Pacer duplex per foot versus Greg's 6GA, 2 separate hot and ground, see the difference.  I just checked 8GA, about a $1.00 less per foot...

Don't get me wrong, I love Pacer wire/cable, and running a single jacketed cable should be easier, but if you simply tape the hot and ground together every foot or so, it acts like one...

Lewmar Profish 700
Model  6656211107-301
Voltage 12V
Typical Power 500 Watts
Typical Max Pull 700 Lbs
Max Line Speed 105 ft
Working Load 175 Lbs
Normal Current Draw 35A
Typical Line Speed 88 ft
Weight 19 Lbs

[Capt. Bob]

What maximum voltage drop percentage are you trying to reach?
Using 3%, you'll need bigger conductors based on 35 amps.

Edit:
Wow,
That's the model I used. :o

[RickK]

You're right - Greg's is cheaper.  I was hoping to get by with a duplex wire but that 53' is probably too close to comfort with a windlass.
I can get 50 ft of 4ga battery cable for $90 delivered.

[RickK]

CB you have the Profish 700?  How do you like it?

[seabob4]

Rick, CB,
Genuinedealz has a neat voltage drop calculator.  Here's the link...http://genuinedealz.com/voltage-drop.html

Just did a try on 4GA at a 48' round trip, 35A draw...3.5% voltage drop.  Close enough for me...

Sorry Rick,
I have a human powered windlass.  :(

What I meant was that I Goggled "Windlass" and used that model for an amperage number. Just coincidence.

[RickK]

Yep, SB you were right, out of the gate.  These babies draw some juice.

Like minds...
