Hi,
In an effort to clear the foredeck on a Macwester 26 I want to move the anchor into the roller on the bow. I need ideas for NEAT solutions to this. I don't want a great battering ram affair sticking out from the bow but rather something that will follow the lines of the stem. HELP! Photos or drawings would be great
Regards,
Antisbarr
 
Put the anchor on the existing roller and secure it with thin rope, ready for quick release when needed. Nor the shaft or the hook are in the way of anything; this is what I have done on my Macwester and it works well.
 
Still can't work out why people with small boats want to perch a big lump of cast iron as far forward as possible, and high above the waterline. Do you want your boats to pitch more than necessary.

(Google 'polar moments of inertia' if you don't know what I'm talking about)

Sticking big lumps at the end of the boat increases the moment of inertia. That in turn reduces the response to torque inputs ...

That's not the issue its one of momentum and kinetic energy and the resultant stimulus on the vessels motion caused by external energy in the form of gravity and impulse due to wave periods.

Any additional weight in the bow or stern will make the yacht pitch (and possibly yaw) more than if the weight was not there.

Its summed up in Newton's second law.

All the best.
 
If you must do it then purchase a Bruce anchor;it has no sharp edges and unlike a CQR type, will form a curved shell over the bow and roller. As to its mooring properties-thats on another thread elsewhere.
If CQR type, then small wooden (or Delrin) blocks screwed to the deck will allow it to be laid on its side, point down. The (three) blocks are made by Seasure and may be obtainable from Chandlers near you.

It's to do with having an anchor ready for instant use. It's a basic seamanship thing.
 
Some CQR Stowage Solutions

Antisbarr,

Type "self launch CQR" into Google and you will find a number of stowage solutions.

An American site with pictures of various products: -

A UK site with pictures of actual anchor stow solutions: -

Good luck and Best Regards

ps Alahol2 - no they don't sit around the middle of the boat low down, they sit on the windward rail bunched round the beam in strict weight order ie heavies in the middle lightweights on the ends. We also only carry one tooth brush.;)

And so is keeping the weight out the ends of the boat. Having your anchor ready for use is good seamanship when in areas that maneuverability is restricted, other wise you can store it away.

This was common and standard practice on leisure yachts not so long ago. The anchor was shipped to a permanent stowage location, lashed down and the chain hole capped to prevent water being shipped down below. On approaching land or a harbour the anchor would be shipped back to its deployment position ready for use. By removing the anchor the bow space is freed up for other activities which a cruising yacht at sea may be required to undertake e.g. deployment of sea anchor and towing rope are obvious examples. I have found the anchor gets in the way and removing it in lumpy seas is not safe.

That was considered both good and basic seamanship, not leaving it stuck on the ends. Times change. Some blue water cruisers may do this, some may not, most coastal cruisers probably don't now. I do on my current boat.

"on approach to land"

Have you not yet realised that many boats do not get out of sight of land? :D


BTW, I hook my CQR round the pulpit stanchion & lash the shackle to the second stanchion. It cannot break free in the roughest overfalls leaves the bowsprit & foredeck clear yet is easily released to be put in the bow roller when approaching an anchorage. I like the bow roller free for warps on my mooring or when tied to the quay - or (heaven forfend) if I ever entered a marina!

I would only unshackle the anchor & stow it below if heading off soundings for a period of several days or more.
 
I crewed on an ARC boat a few years ago, and the organisers made everyone who had their anchors in bow rollers remove them before leaving the marina. I assumed this was to reduce damage in the event of collisions whilst manouvering around the start line but maybe there was some other reason. It struck me as a bit odd to be inside a harbour without an anchor shackled on and ready for use, but it wasn't my boat so not my problem. :confused:
 
sea Rush, good point that I wanted to make...most boats only go out for a couple of hours, especially the "small boats". I understand the theory of keeping weight in the middle, but the weight of a typical anchor wont make much difference in typical usage I think most people want. My boat, 23ft has an anchor locker built in the bow with chain and anchor in it...it is fine.
I keep my anchor ready to chuck over the side all the time as you dont know when you will need it, from experience. Shouldnt be an issue of damaging another boat with it, unless you plan on hitting another boat with it, if you know what I mean...
I have only just joined this group and its fascinating hearing different ideas especially when I also hear from friends who teach sailing about the RYA 'national curriculum', there is no one rule, it seems?

Bit harsh, esp. to a new user?
 
I read about this somewhere. The guys who invented it (for a wartime application like securing Mulberry pontoons?) tried to market it under another name, but it couldn't be registered as it was already in use for sommat else. IIRC, CQR is simply a phonetic spelling of secure.
 
Professor Geoffrey Ingram Taylor invented the CQR and his UK patent application was filed 21 March 1933 ( No: 713,314). The first paragraph reads:

“This invention comprises improvements in or relating to anchors for mooring yachts and ships generally, and may also be used for the mooring of aircraft on water.”

The patent application makes no mention of CQR so I suppose this was a trade name.
