[Rhodes22-list] microbursts on the Neuse

Hi Mary Lou,
Thanks for recalling that. That capsize was apparently about ten years ago
on the Neuse River near New Bern. As a new member of Blackbeard Sailing
Club in New Bern (March 2007) it has special interest to me. It could
happen again.
"I frankly, never imagined that the Neuse River could generate that
kind of wave or that we would encounter a storm of that ferocity without
some kind of warning." - Paul Cleavenger
Blackbeard sits off upper Broad Creek, a tributary of the Neuse. The Neuse
River downstream of New Bern is about 5 miles wide or so and it's 23 miles
from New Bern to Oriental, then another 45 miles from Oriental to Ocracoke
Island on the Outer Banks as the Neuse ends and the Pamlico Sound begins.
It's all thin water less than 20' and, around New Bern, mostly less than
10'. Nice mud bottom most places, like the Chesapeake. Near New Bern the
river runs out from NW to SE, then turns at Minnesott and runs from SW to
NE, a 90 degree turn to the left going out to the sound. Under certain
specific and rare weather conditions this geography makes for unusual water
levels on the river. There's a 50 mile fetch from Ocracoke and big waves
can develop all the way from the Pamlico to Minnesott during a Nor'easter.
When a Nor'easter blows (from the NE, obviously) it blows lots of water from
the Pamlico Sound and it funnels up the river causing pretty big wind tides
on the upper parts of the river. The water is forced past Minnesott and it
has no place to go but to turn right and head upriver to New Bern. A two to
three foot wind driven flood tide is not uncommon in these conditions.
Also, when there is a sustained strong wind from the SW blowing across the
shallow Pamilco it sucks all the water from the Neuse out to Pamilco to fill
the void left by the old Pamilco water now blown to Ocracoke. This happens
infrequently, but it did happen earlier this year and most of the boats at
Blackbeard were left high and dry on the mud until the wind changed.
Applying this background to reading Paul Cleavenger's account of his capsize
on the Neuse, I can easily imagine a microburst or small tornado on the
Pamlico generating "instant effect" wind tide and producing a six to eight
foot wave, with accompanying very high winds, swiftly moving up the river.
Paul's account seems realistic and believable, although I learned from
talking with other Blackbeard club members, it does not happen often.
Cleavenger apparently took the wave on the port quarter motoring home under
bare poles, broached on the wave, and took a simultaneous or subsequent
knock down in the microburst's hurricane force winds.
I have been wondering what, if anything, could be done to better survive in
those conditions. Frankly, I'm not sure any small sailboat could withstand
85 mph winds, but Paul supplies a good answer:
"I have no doubt that we could have probably taken on the storm
without loss if I had understood what we were getting into. By turning into
the storm and taking the waves on the bow, it would have been a nasty ride
but do-able." - Paul Cleavenger
So perhaps bare poles and motoring, turning into the wave at about a 45
angle might be a more survivable approach. How much boatspeed would be
best? Is more speed better to help climb over the wave without stalling?
Or, if given enough time and a shallow mud bottom, would it be better to set
an anchor and assume the wave and wind would approach from the same
direction? I hope someone with more knowledge and experience with summer
storms and eight foot waves than me would comment on this.
The ramps we used on the upper Chesapeake were at Caso Rio Marina in Mayo,
MD, about ten miles south of Annapolis near the West River. It's a
friendly, laid-back place and they only charged $5/night to store the trucks
and trailers.
Best,
PT

I was relying on memory so I had to go look it up. The story is on
the R22 FAQ site.
http://www.geocities.com/blew_skies/capsize.html
Interesting that Stan says "Re "just" floating, the boat floats very
high right side up - but the very design that keeps it high in the
water if it develops a leak, keeps it low in the water when upside down."
