I have to tie my anchor down when it's stowed in my front roller - otherwise it tries to launch itself.

The pin across above the roller would fit nicely though about an 8mm diam hole in the main arm of the anchor, if only it had one.

Anchor looks like it's coated in zincy paint rather than being solidly made of some anti corrosion stuff.

So will drilling though it make it rust?

I guess you need a pic or more info?

Tis a CQR type.

I drilled mine (glavanised bruce type) for exactly the same reason as you almost a year ago.

I just drilled it and left it as is.

Boat in water the whole year and until now no rust.

Works a treat /forums/images/graemlins/smile.gif

I am pretty sure the position of the hole meant that no loss in strength to anchor, which is not the weakest link anyway I would guess.

Yes but you could coat the inside of the hole with epoxy to form a bush that would last a long time.
 
Hot dip [i.e. true galvanising] has a protective effect that extends a certain distance onto adjacent ungalvanised surfaces - it's anodic protection. I have a 1930-ish watering can which demonstrates this effect perfectly
 
Hi Craig, drilling..... I shall have to live with the consequences as I much prefer a large pin. I take your comments on the website seriously although I do not like the hassle of tieing and untieing lots of line each time I anchor. Perhaps if I were a long distance cruiser or liveaboard I may think of the time taken to do things in a different way.
I do need to stow my anchor on the foredeck securely in some form of cradle when the boat is left, as the swinging mooring chain goes through the bow non 'roller' area and the anchor is in the way..
I have thought of using anchor blocks/chocks as I've seen used on CQR type anchors but they are not quite right for the Rocna.
I'm also concerned that my shiny Rocna looks tempting to thieves so a system of locking it down was in mind, although others have said that thieves may destroy part of the deck to get it free. At present I unshackle it and keep it below each time which is not suitable either. Are you thinking of producing cradles to store them?
On another point..... the Rocna is very much easier to handle than my old CQR copy, with no moving parts and the large rollbar to hold onto it is a well balanced load to move around.
I yet have to use it in earnest, but I'm sure I wont be dissappointed.

It does have a sacrificial protective effect. The exposed steel will not rust badly, but it will accelerate the deterioration of the rest of the zinc on the anchor. It is best to use at least cold zinc spray to coat the drilled hole interior.
 
By drilling your jewel you will have vandalised it and rendered it unpalatable for thieves (only joking of course). I would have thought that whatever you do, a determined thief will mage to get at it. If you are really worried about that, you need to put up with unshackling it and taking it below, but I understand that this is unsuitable and a PITA. Someone lashed Tigger's Rocna in a very seamanlike way (there are advantages of cartering one's boat) and I have copied the method ever since. By using the right knot it really is not a problem to do up and untie: no more difficult than using drop pins and other contraptions.
