i haven't had many issues with 32v items... the only thing i coudln't find
were replacement shower sumps or small bilge pumps for the sumps in 32v...
light bulbs are a little harder to find although West has some, Rule makes
the 2000 and 3600 pumps in 32v flavor, similar price...
there are a number of good and reasonable 32v inverters, there was a recent
discussion on the Hatt. forum with many links posted. Charles I think has
them...
when i added an inverter to the boat last year, i decided on a 12v model
since i was going to add a big inverter bank anyway. I also run a few 12v
circuits from the inverter banks (electronics, followmeTV and shower
sumps...) . genset (18kw norpro) is 12v and has it's own battery.

PS enjoy St Maarten... I spent 12 years living on St Barth and used to go to
SXM all the time...

as all the boats we had used 32V systems for engine starting, primary DC
systems, and for all backup power. So when we looked at Mariah, (our 1969
trawler) I was not dismayed about the fact that she has 3--32V banks of
batteries. Two for the house system, (each connected to the P/S main
engines,-the 32V panel,-the pilot house panel,-or the generator bank via
disconnect switches); and one for just the generators. We also have a bank
of 2--12V gel cells in the pilot house for instrumentation, etc. This bank
could be used for powering of the endless convenient items that are so
readily available in 12V however, it is not wired as such and although it
could be, it would not be the bank that I would want to be vulnerable to
'depletion' by something like 'the stereo' or the 'fan' for which power
should be coming from the 'house bank'.

> Reality of this change began, setting in when our 'senior citizen' Dytek
inverter went TangoUniform while down island a few years ago. It was not
repairable there, (really long, but good, story there) and once back in the
States and at Wards in FL we found that there was no longer any data/
schematics for it and NO one could help us. I had already begun research on
new 32V inverters / 'inverter/ chargers' and found that there were VERY FEW
sources (and yes I uncovered them all including those in europe and those
who would 'make one up') and what was available were VERY expensive.

getting more and more that way every day with many things we would like to
have available not made for 32Vs at all and even if you can 'work with the
32V system' if a person looks ahead at all the future it's not there.
> So--we knew then that the time was comming.
> We did, with a 'not so minor miracle', find an amazingly helpful fellow in
NY that worked for Dytek and designed the board for our inverter, (the
internet is truly an amazing animal) sent it to him and got it repaired.
However, reciently the inverter went T.U. again, a couple batteries in the
house bank went T.U. (and they are all due).
> So--we opperate without an inverter, I deleted one house bank, as they're
monster banks and without an inverter their main function is to run the
heads and the bilge pumps.
>
> We will probably never go without one 32V system because ore ancient
anchor windlass is 32V and I've been told it can not be rewound for 24. The
6KW gen-set is made with a 32V tap to charge the gen bank and it's starter
would be expensive too. BUT, the good news is that the Delco starters for
the Cat Mains and the 30KW gen-set are 24/32 volt. and the main alternators
are actually 24V units with a tapping resistor, (mounted on the side of each
block) to 'tell them' to produce 32. So the conversion will be less tramatic
as first thought and the most expensive components, the inverter/charger and
the batteries themselves, are toast anyway.

> BTW: I'll be going back to the boat next week in SXM so will really miss
sharing with the list as I have here in the States. But I'll be reading the
posts and working on putting together an internet connection from the boat
to be able to participate again.
