We left Cape May, New Jersey this morning in fog so dense we couldn't
see either breakwater on the way out of the inlet, couldn't have done
it without RADAR. The expectation was that the fog would lift by
mid-morning and we'd have clear sailing up the Jersey coast into the
NYC area. It didn't happen. If anything the fog got worse as the day
went on and we never saw anything for the entire 113 nautical miles
until anchoring in Atlantic Highlands late in the evening. It was
instrument flying all the way on RADAR, GPS chart plotter, compass and
AIS for the entire trip. There's a nice sense of accomplishment in
doing that but it's also very stressful and hardly a pleasant day on
the water. We'd have waited for clear weather but there's a 3 day
nor'easter in the forecast and we have family obligations in NY next
week.

Sounds exciting. Thank god for RADAR and hope you don't hit a
submerged shipping container huh?

Fortunately submerged containers are fairly rare. Partly submerged
logs are fairly common however, and are a very real hazard to your
running gear. We dinged a couple yesterday but fortunately they don't
seem to have damaged anything. By the time you see them it's
generally too late to steer around. If lucky, I'll have time to
throttle back and shift into neutral. They don't show up on RADAR at
all so no advance warning until they pop up in front of you.

Yup most things like that are invisible to RADAR, they just disappear
in the grass at the waterline. One of our friends says a pallet got
him one night in the gulf. It was slick calm with unlimited
visibility, RADAR on and "thump". Wheels and struts. Fortunately he
was able to limp back to the yard but it was still expensive. He was
going about 30 tho in a big sport fish.


Submerged logs or those floating just at the waterline are pretty much
impossible to see on radar however both the Raymarine and Furuno systems
I had were both capable of detecting and displaying lobster trap buoys.
They don't sit very high over the water surface.
