View Full Version : Anchor re-galvanising

Has anyone had any success / failures with getting an old anchor regalvanised? This 75-pounder is a bit tatty around the edges - and I've got an engineer mate who can include it with a batch of his galvanising, so that I avoid the minimum charge ($175 or so IIRC)

I've had mine "done" a couple of times. You do need to ask if they are happy about doing it (they need to do something ingenious with it to stop the zinc from freezing up the joint)
Getting chain done is very much more difficult. I don't currently know of a galvaniser who handles chain.

I gave the chain away - it didn't look too good. I'm using a new winch anyhow - so want to make sure it matches the gypsy. She used to have 37 metres - but I may try for more.

37 metres does not seem much!
Mirelle has a 45lb CQR and 87 metres of 11 mm chain (well, 45 fathoms of 7/16" chain, to be exact!)
Without getting into a wholesale "anchor thread", I reckon the only anchor that's too big is one that you cannot handle, and heavy chain, because of the catenary effect, is better than light chain!

I had my anchor done here in Seattle three years ago. The galvanizing has worn through at the tip of one fluke, but overall I'm happy with the result.

I had a Danforth and a yachtsman done years ago. They were satisfactory.
Maybe a can of cold galvanizing spray as a stop-gap measure?

You could also have it sandblasted and paint it with white epoxy paint so it is easier to see when it is on the bottom, if it was ever necessary.
Looks better too. But hot dip galvanizing is very good.

Just do it.
I get mine done every 5 years or so depending. The only issue is that some plough types have lead in the tips, you need to re cast that because it goes away in the galv process:rolleyes:
Cold galv is great so long as you keep the anchor off the bottom ,where it scrapes.;)

I agree - too short a chain. We dragged that anchor in Farm Cove when we were in there for the closing ceremony for the Sydney 2000 Olympics. We were anchored in about 35' of water when the fat controller on a Waterways boat made us "move 10' further into the Cove" - despite the fact that we had enough swing to clear the exclusion zone buoy. It was gusting to 45 knots at the time. Here's the anchor laying being undertaken by a trio of loveable boofheads from Batemans Bay, the previous evening. One of these guys had "mooned" the Manly Ferry about 10 minutes earlier. Just wonderful!

The reset was the same three guys hauling by hand - then moving, it didn't set and we were already close to shore, so up again (not all the way of course) and it bit the second time round.
The Waterways guy ended up putting another boat further out than where we had been. By the evening of the closing ceremony - this area was wall to wall boats.
This guy behind us:

learnt a valuable lesson in anchoring. He came in during the afternoon and dropped his pick in front of about 30 photographers on the shore who had been there since dawn in order to secure good spots to take photos of the fireworks and the F111 ignited fuel dump. People were screaming at him to move (his rigging being the problem) - the Waterways Authority and Water Police asked him to move, but he refused. He was even offered another spot ....... but "I'm allowed to anchor where I want, and I want to anchor here". As soon as the sun went down, the bottles started raining out of the sky ..... and he moved.
The fireworks were good!

I had a young lady guest come aboard when I was in St. Thomas.....a friend of a friend....before she came I gave her the do's and don'ts and one of them was the cell phone, the big ugly things of the time that looked like WWII walkie talkies......I specified music players must have headphones etc......
She brings her stuff out in the dink (water taxi) and she has a portable 12 inch tv.....I told her she was welcome aboard but the tv had to swim......she shrugged, and dropped it in the harbor. Turned out to be a nice lady.....:D

Make stainless steel anchors......can send patterns..
I made three anchors last year A 45 POUND DANFORTH, A 65 POUND CQR AND A 60 POUND TAKE APART FISHERMAN, THE OTHER ANCHORS WERE PARTIALLY FOLDING, OR FULL FOLDING BASED ON THE DESIGN......HIGHLY POLISHED AND THE LOOK GREAT. $350 FOR THE SET, PLUS FREIGHT, WHICH WASN'T A LOT.TOOK 6 WEEKS TO ARRIVE BY ELEPHANT CARAVAN.....slow freight

Funny you should mention that ...... I was, at one stage thinking of putting a plasma in, but they are a bit heavy on current draw and my genset is a bit noisy. We did have a 12" TV on board that night - and 21 people crammed into the salon trying to watch the televised coverage of the closing ceremony before the fireworks started where we were.
No, that isn't a BBQ - that's the exterior steering station compass. I've displaced it with the new set-up and have the throttles there now, but it will find its way back on board eventually.

Chuck ..... tell me more, please..... electonic?
I'm thinking of making a stainless steel sampson post / bitt setup. Barry & I put a new sampson post in during the rebuild of this area - and spent time making sure we had the rather heavy damn thing lined up with the bow - but the shape of the hull is different side to side back where the poist is, so to get the teak planking right, I need to have the post about 50mm to port. That means shaving 2" off on side and adding it to the other - which probably wouldn't be the smartest way to have a secure boat, so, if I take the post down a bit and cap it with a SS bolt-through setup, I think I'll have it just about right.

Which lines up with the bow roller

but not the teak - but it will!

Excellent Chuck.
Now for some real thread drift (appropriate in an anchor thread)
Here's what we got during the fireworks show that night.
