Yes, I've heard that the cable can become very stiff and this can cause
problems. I plan to fix the ends firmly in place with rubber covered
metal
clamps.

Not sure what you are getting at here.

I may go to crimping if I can find a place that can do a good job
on this size cable.

You can get an inexpensive crimper at West Marine. Does a fine
job on 2/0 cable.

As for not using tinned cable, I guess this will work
but it is very hard to heat up such thick copper cable and this might
compromise a good all-round tinning of bare copper.

This is why soldering large cable is not recommended. Take a look
at the starting cables in your car. Not likely you will find a soldered
connection. I used to have a copy of a NASA Tech Briefs that had
a good article on soldering vs crimping. They found crimping more
reliable for many reasons. Micro-cracks in the solder joint eventually
lead to corrosion and mechanical failure due to thermal cycling
were among the culprits.

Actually soldering terminals on such large cable is not
recommended. The solder wicks up into the wire
under the insulation several inches and results in a
situation that is very suseptable to cracking over time
to due to vibration. In any case, one normally tins
the end of a wire before soldering it anyway. No need
to pay top dollar when only the ends need to be tinned.
Better to just crimp the terminals on and then seal against
moisture using adhesive lined heat shrink.

Lots of folks use welding cable rather than the tinned marine grade
cable. It's alot cheaper and more flexible.

In my case the welding cable was priced at $1.04/ft but I decided to
buy
the tinned battery cable at $1.69/ft because I planned to solder
terminals
to the end. I expect this will be more successful if I start with
tinned
cable. (I think the normal price for the 2/0 welding cable was
something
like $1.39 but they had a spool going for $1.04)

I prefer to have the windlass and bowthruster to be powered
primarily
by the engine when it is running. The Eliminator from Ample Power
is basically a DC/DC charger but it will add $300 to the project.

The concept is that that windlass battery is used so seldom that

trickle charge it. Personally, I installed the heavy cable and
generally
only run the windlass when the engine is running. An extra
battery,
extra charger, etc seems more trouble than it is worth.

OK, I see. Doesn't seem very reliable to me...solar/wind depends
on
good weather, AC-DC charger requires an inverter or being on shore
power, and I'm not sure there's a DC-DC trickle charger.

ps. When did the word "ampacity" enter the alphabet?

It's not in my vocabulary either, check the person who used it ;-)
