I'm now working with the shipyard and engineers who are doing the
final design and engineering for this vessel:

The electrical subcontractors were at the last meeting and I asked
them about using AGM batteries in the boat. They said they wouldn't
consider using anything else. I said, "Safety?"

They said, "No, better performance. The safety is just icing on the
cake."

These guys not only design the electrical systems for very
sophisticated vessels but things like remote telephone switching
stations and computer server sites. A lot of the systems they design
run unattended and a battery explosion could create damages up into
the seven figure range.

I'm sure that, if you like tinkering with batteries the way Larry
does, wet cells make sense as a hobby in themselves. There also may
be some advantages for boat spending long periods in remote parts of
the world. For most of us though, this is the most knowledgable vote
I've heard yet for using AGM's.

a really stupid interior design. The entire accommodation is
ill-conceived and obviously designed by a lubber. Why put the berths way
forward for the roughest ride possible? Duh! Move the berths aft as far
as you can get them in the accommodation. Put the heads up forward.
