THURSDAY, PM
Southwest winds at 15 to 20 knots and head seas of 1-2 feet continued as we approached the Chesapeake Bay shipping lanes on a southwesterly course to Cape Henry and the Virginia Beach / Norfolk area. It was just after noon. In terms of our cruising strategy this is the stretch where we would need to make our third major route decision. Whether to continue on the open ocean around Cape Hatteras, delay at Virginia Beach waiting for favorable weather or continue to Norfolk and take the ICW from Norfolk to Beaufort.
There were two other critical decision points earlier in the trip. One as a crossed out of Buzzards Bay where we needed to decide whether to tuck in to Long Island Sound and one at Cape May where we would elect to cruise up the Delaware River and then down the Chesapeake Bay. Both of these decisions effectively increased our time enroute by increasing the distance and limiting our night travel. If we had elected both we would have added over a hundred of miles (12 hours) and at least three days. We opted to run outside as the conditions, while not perfect, we easily within the 63's capability.
Weather, as always, is the key ingredient in these route decisions. The decision to go to Norfolk and take the ICW increases the trip by one full day as we can only run during the day. It also has the potential to add another day if the decision is related to high winds. The Alligator River Swing Bridge will not open when winds exceed 30 knots. This proved to be a problem on the trip north last spring when we were delayed by high winds in Belhaven (Dowry Creek Marina).
We have been watching the weather intently since departing Hingham so it was no surprise when we reviewed the weather from Cape Henry to Ocrakoke Inlet. (Note: Cape Hatteras is in the center.) The forecast was not good. Below is the synopsis:

Notice the 25 to 30 knot winds and 6 to 9 foot waves forecasted
for Thursday night. This would have dictated stopping and that probably was the
prudent thing to do. However, the wind shift to NW after midnight
influenced my decision. Since we would be running close shore the shift
to NW would put the wind on our starboard aft quarter in effect putting on a
lee shore. The only question I could not precisely answer is when the
frontal passage would occur.
Explanatory Note: Waves are a product of
wind and there are three factors that effect their formation; the speed of the
wind, the time of the wind and fetch, the size of the area over which the wind
is blowing. The higher the wind speed, the longer it blows and the amount
of open water dictate wave height. On Lake Michigan a 20-25 knot wind
blowing out of the north east produces 10 foot waves on the Chicago lake front.
As we proceeded south just past Currituck
Light at 4:45 PM we had south southwest winds at 18 to 20 knots with a 1 to 2 foot head sea.
Sunset occurred at 5:07 PM and at 5:59 PM we lost nautical twilight.
At 8:18 PM just south east of Bodie Island Light I noted head seas of 2
feet with SW winds running 25 to 30. The 63 in not noticeably affected by
head seas under 4 feet. Hence at 10:18 PM we were riding smoothly even as
the the head sea built to 3 feet in the continued 25 to 30 knot southwest wind,
At that point we had covered 532 nautical miles since leaving Hingham.
Shortly thereafter satellite weather showed
the area between Currituck Light and southwest of Cape Hatteras under a severe
thunderstorm warning. Cells were
visibile both on sat weather and also on my radar screen moving northeast and
were northwest of our position. Satellite weather showed the cold front 157 NM
west of our position.
As a general rule thunderstorms and rain showers occur ahead of
the front. Further, frontal information
unlike Doppler radar is not immediate.
Hence the front’s exact location was unclear.
At 10:51 PM a cell visible on our radar crossed our position with
heavy rain and gusts to 39 knots (45 MPH) and the wind shifted northwest. Nine
minutes later we crossed our next waypoint and changed course to 186 degrees
putting the wind on our starboard aft quarter. At 11:00 PM I recorded 30 knot winds
out of the north northwest and a peak gust of 49 knots (56 MPH). Between 10:51 and 11:00 seas quickly built to
an estimated 6 to 8 feet. Fortunately we
were experiencing a following sea.

We were in big seas with gale force winds just 2 hours northwest
of Cape Hatteras. Clearly a raging
storm. However, we experienced its intensity
by looking at the waves through the window, which is not easy at night, and
reading numbers on the instruments. We could
not hear the wind due to the integrity of 63’s construction. It was surreal. The photo below is of my notes for the hours
before the frontal passage and for two hours afterwards. Notice that the legibility of my writing does
not change. This speaks to the amazing
stability of the 63. Thank you Outer Reef.
Our next challenge was Diamond Shoal. From Cape Hatteras, Diamond Shoal juts out 17
miles to the southeast. Noticeably there
are no depth numbers on the chart suggesting that bottom tends to shift
around. Bottom line. You have to go around Diamond Shoal. In our case, we wanted to round Diamond Shoal
and then immediately head northwest into the wind to get close to shore and take
advantage of the lower seas created by the lee shore (i.e., reduced fetch). The question here was how would the 63 perform
in the different points of sail as we rounded the shoal.
At 2:13 AM we turned to starboard (266 degrees) which put us on a
beam sea. Waves were 6 to 7 feet with
winds out of the northwest at 25 to 30 knots. The stabilizers were giving us a
stable ride. An hour later (3:04 AM) were
turned northwest into a 6 to 7 foot head sea.
Again I recorded “stable ride despite high winds and seas." The rounding of Diamond Shoal (Cape Hatteras)
demonstrated the 63’s sea worthiness.
At 4:03 AM we were off Hatteras Inlet in a head sea of the starboard
quarter. Winds were northwest at 40
knots but owing to being close to shore the waves were only 3 to 4 feet. Lots of spray from the wind but a very
stable ride.
At 6:19 AM we were off the Ocrakoke Inlet Open Water Buoy on a
course of 237 degrees. Winds were NNW at
29 knots. We were enjoying 1 to 2 foot
seas as we cruised within one mile of shore.
We were finally getting the full advantage of the close-to-shore
strategy.
We continued on toward Morehead City rounding Cape Lookout at 11:57
AM. Winds were now 19 knots. At 2:20 PM we entered the Morehead City Inlet. We had covered 661 nautial miles since
leaving Hingham three days ago.

We stopped at Morehead City Yacht Basin, refueled and by 4:00 PM
we were headed outbound to continue on to Stuart. Stay tuned for my next article “Life in the

Below is the note that I
wrote to Jeff Druek, President of Outer Reef.
Dear Jeff,
We transited Cape
Hatteras Thursday night during a very strong cold frontal passage with wind
gusts as high as 49 knots. Seas built very quickly to 7 to 9 feet with
sustained winds of 30 to 35 knots. All this happened as we were
circumventing Diamond Shoal, which puts us at least 17 miles offshore and
required course changes encompassing 270 degrees. We went from a
following sea to a quartering sea to beam sea to another quartering sea to a
head sea at the height of the storm.
Notwithstanding the flaw
in my judgment for being out there (I took a calculated risk), the 63 showed no
flaws in terms of its sea keeping regardless of the point of sail. The experience
is almost surreal. You cannot hear the roar of the wind due to the boat's
amazing quietness and since it was night, it was hard to see the wave heights.
The boat just moved through the turbulence with sure footed stability.
Sir, you and your team
build an amazing boat. I was confident that the 63 could handle heavy
seas when I bought it but now I know from experience how stable she is.
While I will continue to adhere to my conservative approach to heavy
weather I will have the confidence that should the unexpected happen the boat
can handle it.
