This is Philip's tug. Rather normal looking from the
outside. I like the red light on top.
This is the tug with a 545 motor and 40mm 4
blade brass prop and 12 volts, named simply, The Wolverine.
The larger 545 motor is recessed further up
into the motor tray so it will be centered to the prop shaft. The
hull & deck are joined with a non-hardening silicone RTV (Safe for
oxygen sensors, doesn't give off a vinegar-smell acetic acid, won't
corrode circutry.) sealant so it can be
taken apart for easier service or repairs.
The two 5 cell packs in series sit well in
the hull. There is plenty of room to fit a r/c car heat sink on the motor
and a fan. The idea of the 545 with the larger prop is to run at
lower rpm to do the same work as the 380 and small prop so everything will
run cooler. It purrs.
You'll see the tug pushing 2 Fairwind yachts
that are joined at the Jib boom. The attachment hole of one Jib boom got
caught under the railing of the other. The Fairwind yachts are 36 inches
Pretty cool that the tug had full
control over both and turned them any which way as if they weren't there.
I had the tug do a 360 so everyone could get a photo of the once in a
The working strobe serves as a defensive
driving tactic so it won't be run over during a regatta while pursuing a
disabled yacht. Bobber lights also make good Navigation lights.
