Anchor system name

[Arthur Garfield]

Hello cruisers,
Hope I have image up of an anchor in bow system.

My question is-what is this called/named??

[Arthur Garfield]

The above image looks like a "Rocna" type anchor though curiously
Shankless!

Seems chain directly shackled to "plow" fluke with the "rollover" bar arch.

Any thoughts about this? holding? reliability? Negatives?

Looks like two cqr type stainless anchors to me, or are you asking about the rollers thru deck?

[Arthur Garfield]

Hey Hi Greg,

Ok, CQR.

Yes,was asking what is formal name/system for thru bow sys.

Like,what descriptor to use to google/research this type configuration?

&,Additionally,what thoughts people here have about this sys?

[JPA Cate]

Try Googling on "Dual Roller Anchoring Systems".

Most such systems are not "through the bulwarks" kinds, something usually seen on larger boats, and motor vessels.

Hawse pipe?

Not my favorite source.

Looks like a big steel boat?

CQRinbowroller&hawsepipe is the official name.

Don't like the arrangement. The "snout" looks like it could be stuffed when hitting a serious wave, bringing water into the boat, and much of the interior would appear to be taken up with winches to handle the anchors. I prefer handling anchors from the bow, particularly when recovering them so to wash chains with fresh water and clear any vegetation and muck. Besides, having the chains not from the bow's very front, would seem to allow scraping the hull.

Incredible boat. Look at all those real dorades, the electric furler, the roller-type clutch on the windlass, the tracks on the mast... money is not in short supply. Judging by the dark buildings with small windows, it's in Northern Europe somewhere. London? Holland?

The boat is almost certainly metal - probably steel but possibly aluminium - judging by what appear to be neat welds on the cheeks of the anchor rollers, the rubbing strake, and the tang to which the babystay is attached.

Being a metal boat, the hawse pipes are probably welded between the openings in the stem and the surface of the deck. If anything, that setup would result in a structurally stronger stem and foredeck, compared to a "standard" anchor roller. The chain stopper is visible on the deck, as is the windlass, which suggests all the anchor handling is up on deck, and not internal. It would be just as watertight as a normal anchoring configuration.

It would also be difficult or impractical to achieve with anything other than a metal hull, and retrofitting would be near-impossible even on a metal boat. The thing was crafted that way while the hull was still nothing more than shiny alloy or primed steel.

The only let-down, for me, is that they're persisting with CQR anchors which are generally acknowledged as the worst of the old-generation anchors, in terms of their setting reliability. Perhaps it's because the hawse pipes and rollers were so customized for the CQRs that nothing else fits. Perhaps a set of Vulcans would sit there without modifications, even if standard Rocnas do not fit?

The other thing I don't understand is why two comparatively small anchors instead of one large one of equal weight? Yep, redundancy 'n' all, but for a given weight a single large anchor provides much sounder sleep.

Personally, my notion of "perfection" is that type of hawsepipe setup, but only one, right through the very stem of an unpainted alloy hull

[LongRange]

Looking even more closely, it's an aluminium alloy hull, I'm virtually certain.

The tang to which the forestay is attached has a second attachment point which is not being used, and therein is visible a ring of stainless steel to prevent chafing and elongation of the alloy. That is typical of no-expense-spared alloy construction.

I call it a terrible thing to do to a pretty boat. Those hawse pipe roller things are just ugly.

I would agree on likely alloy. The thickness of the cheek plates on the rollers would be off scale in steel... I think!

And your eyes must be better than mine to pick out that s/s ferrule in the baby stay tang, if that is what it is.

Yep, a nice boat!

Aw, I dunno! the view from on deck is much cleaner than with a standard set of deck level rollers, and that is where the owner (bill payer) generally is looking from.

Anchoring gear is not often pretty! But CF member captmikem at one time commanded a beautiful Palmer Johnson cutter called Turmoil. It had a kinda complicated mechanism which rotated the whole anchoring sprit, roller, anchor and chain and hid it in a big hole in the foredeck, leaving a clean bow. It was the first thing I noticed as we passed by in our dinghy (in Tonga, a long time ago): no anchor or gear visible at all (she was on a mooring at the time). An outstanding boat in so many ways, all 82 feet of her (IIRC). If anyone is interested, perhaps Mike would give more detail on that system.

Ferrule, that's the word I was looking for. Thanks

The forestay tang, not the babystay. It even looks like bare unpainted alloy, probably close to 20mm thick.

Looks like an 80's boat. Back then CQR was pretty much the standard. I'm fairly sure the hawsepipes were specifically designed for those anchors and I bet fitting anything else without them scraping or rattling would be difficult unless you had custom anchors made. Also when you have $15k in stainless anchors you're probably not keen to change them out...just have your paid crew stand watch
