And what if you are anchoring in 100 feet of water.. very common on the west coast.. not to change the subject but we carry 400 feet of chain, all 3/8 BBB, and a 45 lb CQR and have anchored more times than I can count in deep of 100 or more feet ... and the windless always does its job bringing it up.........

Jeeze Randy--You've got 400 Ft of 3/8" in the chain locker? That's some 650#+. That's a terrific load in the bow of our boats, no?

Could you help us all out with a side on pic of your boat carrying 400ft of 3/8" chain in the bow locker plus a 45 lb anchor on the bow roller.

I think you under-estimate the strength of our boats.. for the weight on the bow, hasnt cause any problems, and I've also got Two (4ds) crammed into the locker infront of the berth.. they weigh in at about 135 each..
with the chain and batteries loaded, she still sets with the waterline a couple inches down from the boot stripe..

Head office will be found just off some nice white sandy beach, look for a unshaven dude crashed out on the tramp of a 49ft Cat, that'll be me hard at work

Cunning plan don't you think?


Now gotta go find a 20,000lb anchor in a real hurry. Just had the call a ship just lost it's one and can't leave port until it gets another. Oh joy... not.... unless you're an airline in which case do I have a job for you.

Did you find your 20,000lbs anchor???

20000lb anchor -

Picture looks OK to me.

and right at this moment, the anchor, (setting on the dock) and 200 feet of the chain (under the table) are awaiting to be re-galvinized.. we've worn off the exisiting galvinizing over the last few years..you can also see the boat sets a little higher when all is unloaded............

By the way, just read another thread concerning "amount of Chain" and a post from Mark stating he carries 330 feet..
those having just a short length of 150 feet or less will have a rude awakening when dropping anchor in the rocks somewhere and finding out the "rope rode" has cut itself to pieces on the bottom...

back to the issues at hand.. your windless SHOULD lift 100 to 150 feet of the anchor chain you use plus your anchor.. If not more.....
Sorry for the thread drift......

This is not to you but to the chap with the winch problem.

1 mere of calibrated 3/8 chain weighs 1.35k per metre

400 ' = 121.92 m
therefore 400ft of 3/8 chain weighs 164.592lbs
add the anchor at 45lbs
Total 209.592lbs.

You will find that most manufacturers info quote the usual type of thing below.
Get the info then sort it out. if its supposed to lift it and it does not then you got a problem.
If you don't know the specifications your wasting your time and everybody else's get all the facts straight then perhaps someone can help you otherwise everybody is just guessing.

system.
Standard version Crystal 600 / 600 D
Motor power 500 W
Motor supply voltage 12 V
Maximum pull 1367 lb
Maximum working load 441 lb
Working load 144 lb
Current absorbtion @ working load (1) 60 A
Maximum chain speed (2) 81 ft/min
Maximum chain speed @ working load (2) 58.7 ft/min
Weight - Crystal - [without drum] 21.2 lb
Weight - Crystal D - [with drum] 23.6 lb

We have two 75# Bruces, each with 400' of 5/8" chain at 1,275# each side. We also notice the bow ride higher in the water when we have 200' of rode out. I hated having to manually weigh anchor when we had problems with our windlass batteries!

This might be better But does it solve his problem that is the important question.

1 mere of calibrated 3/8 chain weighs 1.35k per metre
8mm short link.

Lb/ft KG/M
0.9 1.4

8mm Middle Link
Lb/ft KG/M
0.8 1.2

8mm Long Link
Lb/ft KG/M
0.8 1.1

Anchor
45 lbs = 20.411 656 65 kilogram

400 ' = …………………………………… 0.9lbs x 400 = 360lbs + 45 for the anchor = 405lbs
400 ' = 121.92metres = 1.4kg x 400 =170.69kg + 20.412kg for the anchor = 191.1kg

So 100 foot out 90lbs
So 150 foot out 135lbs
So 200 foot out 180lbs
So 250 foot out 225lbs
So 300 foot out 270lbs
So 350 foot out 315lbs
So 400 foot out 405lbs

Nah, don't bother with the humble bit just check the numbers.

Even if the figures are accepted at face value the figure of 164.592lbs should be kgs. Small error but big difference. Despite that, the calculations themselves are incorrect.

You are reading numbers for the wrong size of chain which seems to be 8mm. 3/8" = 9.5mm so you may be thinking of 5/16" chain with your calculations. The boat is American so lets take an American brand of chain. Euro chain does have slightly different sized links and hence weights. Based on Acco G4 chain the system including anchor would weigh 685lbs. If the chain is BBB the total weight will be 665lbs. Acco quote the weight of 1ft of 3/8" G4 at 1.6lbs and BBB at 1.55lbs.

svHyLyte was pretty much right with his estimate. It would be like sailing around with four large crew standing in the pulpit. Not good.
