I'm curious why you have such massive ground tackle. What's the
displacement of your boat?

===

Heavy ground tackle is the cheapest insurance you can buy, especially
if you cruise in an area known for strong thunderstorms and wind
squalls. Some light weight anchors have a great deal of holding power
*if* they are carefully set in their preferred bottom type, and *if*
the wind does not change direction during the night, and *if* there is
never a need to set the anchor while the boat is moving.

I've heard of people who carry a heavy anchor stowed away for extreme
conditions. That's all well and good if you have time to dig out the
storm anchor and get it shackled up but I personally prefer to have my
best anchor on the bow and ready too deploy when needed.

You should modify your preference. Having that heavy pig of an
anchor ready to go is smart. Having it on the bow is dumb. Instead,
try storing it all shackled up and ready to go but on chocks
amidships. Keep the weight off the ends to decrease the hobby-horsing.


The problem with such a statement is that while it sounds logical it
really isn't correct.

Longitudinal stability is not effected about the amount of weigh in
the ends, per se. It is the percentage of the vessel's total weight in
the ends that has the effect.

A sixty or seventy Kg. anchor in the bow of a , say 25 - 26 foot, toy
boat will likely have a decided effect on longitudinal stability while
the same weight on a, again lets say, 50 ft., properly built, cruising
boat will likely not even be noticed.


You speak without knowledge of immutable laws of physics.

The heavier the pendulum the longer it swings.


Ah, but a boat isn't a pendulum, it is a
tetter-totter. Unless, of course, your boat floats in a vertical
position, bow down. Sort of like a buoy that marks an anchorage.
