I’ve been looking at the TackTick instruments for a while now,
though there are other priorities on Bright Star at the moment, the
loss of my Datamarine wind instrument started my thinking about
them. According to their website, their instruments will actually
receive a charge even from indirect, under-the-dodger light. I still
planned to wire it into the 12 v system as backup, and as was stated
before their repeater requires the power too. Running power to the
masthead sender seems to defeat the purpose, but if the cells are as
efficient as they are claiming, then even cloudy days shouldn’t be
an issue. Also, since I believe it is the displays that do most of
the processing (since the wind vane doesn’t need to be aligned at
the masthead, but can be adjusted at the instrument, I’m assuming
that’s where most of the processing power is), it makes sense that
the displays may still need to be wired in. the real advantage to
Tacktick is, of course, the wireless aspect, not the solar power.
My only concern about their product is that I heard anecdotally that
the wind sender unit isn’t as robust as it could be, but that was
two years ago. Also, the square displays aren’t going to fit my
round datamarine holes, but… that’s just another project.
FWIW, I’ve started doing nearly all of my electrical business with
Jack Rabbit marine out of Stamford, CT. They are extremely helpful,
their prices are lower than West, and their website has some very
good ‘webinars.’ The two currently online are “Battery Layout”
and “Installing a Battery Monitor.” Good information. I mention them
because they recently told me that they would be expanding their
instrument collection to include Tacktick and a few other brands of
networked instruments. Part of their intent is to help sailors sort
through all of the options when connecting instruments. They’re
definitely worth a look at www.jrenergy.com
