[C38] Knott Transducer

Thu Jun 12 14:50:42 EDT 2008

I just installed the Furuno 1715 radar with 20 meters of cable on the Mighty
Quinn.  The unit comes with a 10 meter cable, but it is not possible to
mount the screen near our helm with that length.  I was first told I could
not return the 10 meter cable in exchange for a 20, so I explored splicing
two 10s.  The engineers at Furuno were very clear this was not an option as
tolerances are pretty limited.  In fact, the 20 meter cable is the longest
that can be used on this unit due to loss.

A personal update.  The Mighty Quinn is currently at Sault Ste. Marie,
Michigan waiting for a crew member to join before we sail the really big
lake (Superior).  Weather has been challenging thru Lakes Ontario, Erie and
Huron with fog you could cut and rain and wind!  The weather fronts have
been going thru almost daily... and it has been cold!  An apology goes to
Russ Duff for not stopping by in the Detroit River, but we were running late
and a southern wind helped us beat the strong currents all the way to
Huron.  Two more days and it will be a month since I left Albany, NY.  Lots
more than a thousand miles under the keel already and at least another
600-700 to go! I am longing for summer to finally happen!
