Now probably best to be careful when pointing out the other guy's miscue. Pernicity? Assuming you meant "Pernickety" as in the British term for "Persnickety" meaning fussy, difficult to please, finicky, over fastidious. "Pernicity", a noun meaning celerity or swiftness. Actually quite an archaic term.

Quite right, an early morning mental typo.

Yes, some dictionaries do describe it as an 'archaic term', which is often what I feel in the early mornings,archaic that is.

So, perhaps I'm not being too pernickety in claiming a certain 'celerity or swiftness' in defending my old Statistics lecturer.

However,it is the least i can do to acknowledge that 999% may also have been a typo.

Instead I have a 100lb manson supreme

Obviously unusual craft like yours require unusual applications to balance their unusual mass and shape.

The usual rules of thumb apply nicely to usual craft but are a mismatch for those that aren't typical.

look up the principles of how large ships anchor and compare it to small vessel situations...can't use their rule of thumb.

Yes if you size compared our trawler anchors to ships anchors either by mass or volume ours would come out HUGE.

The professionals are confident .. we are not it seems.

The pros are manned 24/7 and usually anchor to wait for a pier opening so they can unload.

In some anchorages (like Delaware Bay), the USCG usually requires them to run their engines and have an underway crew on watch when winds are forecast to exceed 35 knots.

Thanks everyone for the advice. I think I will be going with the 70lb plow with a danforth as a back up. Most folks that cruise the inside passage seem to use the CQR or plow. Now I need to practice anchoring. I have never owned a windlass so this will be an adventure.

Oh man! That anchor is too small, it's the wrong kind and you don't have enough chain.

Well that didn't come out right did it. I will be using the 70lb lewmar plow anchor with all chain rode as my primary and the 40lb danforth will go in the hold as a spare.


Better?

Sea-Duction, I think it's a rule on marine related forums that no matter what anchor you choose, it's too small, it's the wrong kind and you don't have enough chain.

Me? I think you have chosen well. I might go with a Delta Plow instead of a CQR because the Delta will self launch off your pulpit. Both are sold by Lewmar so I'm not sure which one you had in mind.

See? I told you someone would say it's the wrong kind.

Must be a bunch of old geezers on this site still talking anchor weight. Forget the weight it's holing power-setting ability-digging ability-resetting ability-structural strength. Within a particular anchor type size and weight will matter but not so important when comparing different types.

Just because I'm 74 that's no reason to call me a geezer.

But yea your'e right ... about the anchor weight I mean.

Design is however more important but once you've picked a design weight is important. But even one pound of weight in excess is bad seamanship.

Minimizing weight on your boat makes it a better boat and you a better Seaman.

This thread has me a bit perplexed. Most of the discussion seems to revolve around anchor weight and design, or size. Anchor size and weight are used interchangeably and the 'bigger is better' theme is common.

My working anchor is a Fortress FX23 which only weighs 15 lb. and replaces steel fluke anchors up to 28 lb. According to the manufacturer's sizing chart it is recommended for boats 39-45' which is one or two sizes larger than what is recommended for my 30' boat.

So, for average use, is my anchor really too large? It is easy to handle and has never failed. Can it satisfy the 'bigger is better' concept at only 15 lb.?

There is such a large weight difference between a Fortress and anything else it is difficult to make any meaningful comparisons. I suspect as long as I cruise in areas where the bottom is suited to the over-sized Fortress, I should be OK in just about anything I am likely to face.

Each type of anchor has its abilities and usually one matches the manufacturers tables of recommendations against the boat type weight and use pattern. So a 15 lb anchor of one type might be rated by that company for a boat that another company suggests a 35 or 40 lb anchor of a different type. With anchors you are dealing with oranges and apples and you just have to decide which fits you taste so to speak.

You're also dealing with ratings and some effort to sell you on the fact their 15 lb will do more than their competitors. The ratings are not absolute.

True but the ratings can be matched against the many test of setting and holding power such as those done by practical sailor magazine for some degree of verification..
