what an absurd response!
For the willing: solid wire is intended for Ac because the current travels
thru the average of the thicknessas it alternates polarity. Dc travels on
the outside (skin effect) due to mutual repulsion of the electrons;
therefore stranded wire is best for high current loads of Dc. If the wire
is well supported and larger than necessary for the rated current AND
cheap enough vs stranded, then go with it. Otherwise, stranded.

Skin effect is something that occurs at higher frequencies. At DC the
electron distribution is equal through the CS of the wire. Skin
effect can usually be ignored below 50 kHz.

I've heard different opinions what kind of wire is better for wiring
boats.Could you give me some of your expertise?
Thank You,

solid wire work hardens and breaks under vibration. Anyone who suggested you
use solid wire is not someone you want to listen to again.

WHAT KIND OF VIBRATIONS YOU HAVE ON THE SAILBOAT EXCEPT ENGINE AREA ?

The normal rolling, rocking and especially pounding that boats do can be
enough to impart some motion on any unsupported wires. It doesn't have
to be much, just repeated enough times so that the point where the wire
is flexing work hardens. There really is a reason people use the more
expensive stranded & tinned wire on boats.

how many do you need?

want more?

waves lapping, hobby horsing, harmonics from wind against the rigging,
harmonics against the sails, harmonics against the hull, harmonics from
climbing the wave ...
.... plus second harmonics of all of the above plus others ..

plus third harmonics of all of the above plus others ..

.... plus fourth harmonics ...

wow, amazing informatioin from a guy without any boating experience!

HULL FLEXING! WAVE INDUCED VIBRATION! POUNDING! DOCKING! STICK WITH TINNED
MULTISTRAND MARINE WIRE! CAN YOU HEAR ME NOW? ;-)

I'd use stranded. The only application of solid wire I recall was in
telephone central offices, and telephone jack wiring in houses.
As others pointed out, it doesn't take much flexing to work-harden
solid wire and crack. But even stranded needs strain-reliefs
and clamps.

Solid wire like Romex is used where you can attach it to some fixed
surface - like a building especially inside of walls. In that
application (i.e. stapled or attached to the building) stranded wire
will not work because the strands will work against the attachment and
eventually the strands will break and cause a short. Stranded wire
isn't allowed inside of walls IIRC, nor can you tie or restrict the
movement of a stranded wire.

Tinned wire is just something to keep the exposed ends from corroding.
We've used welding cable to wire up batteries in an electric car and
it works fine. It may not have as long a life as tinned wire but it
depends on how long you want it to last and whether the cost is worth
it to you. I understand that Home Depot in Tampa carries tinned wire,
but I've never seen it anywhere else.

The main thing is to use a large enough gauge wire for your
application.

Never use solid core wire on anything that moves, vibrates, or flexes- Cars,
boats, elevators, trains, etc. Solid wire is for buildings, signs, etc, that
never move. Movement will eventually break the wire (or just cause it to
weaken, creating a point of resistance that will be a fire hazard)
