Southbound 2017: We Set Another Record

A normal trip takes 9 days, weather permitting. The plan is to depart Hingham at 7:00 AM, cruise non-stop for three and a half days to Morehead City where we refuel, hopefully in two hours or less. Then it's back on the road for three more days with a goal to reach Clewiston Florida at the south end of Lake Okeechobee at sunset on the evening of the seventh day. From there we cruise to Fort Myers where we again stay over night. The following morning we head for Sarasota where we arrive at mid-afternoon.

The total mileage is 1,430 nautical miles.

This plan is rather aggressive as you must hit certain time deadlines to make it work. The most critical is run on day seven to Clewiston. In order to make Clewiston, I have to reach the Stuart Inlet before 7:30 AM and then cover 77 nautical miles of the Okeechobee Waterway, including two locks, to reach the goal just after sunset.

That said, the record breaking Hingham to Jacksonville leg dramatically altered our schedule as we were now running 12 hours ahead of schedule. The key consideration for the remainder of the voyage is the Okeechobee Waterway where two factors, the inability to run at night and locks that close at 5:00 PM, impose severe limitations on making distance.

So, as soon as we departed Morningstar Marina (5:48 PM on Day 5) we began to consider our options. The principal consideration was the 200 nautical mile distance to the Stuart inlet. With our cruising speed of 8.4 knots we cover 200 miles every 24 hours. This would put us at the Stuart Inlet at 6:00 PM and require that we stop at Stuart for the night.

That stop would also dictate the runs for the remainder of the trip. On Tuesday we would leave Stuart at 6:30 AM to arrive at the St Lucie Lock at 7:30 AM, and then run for 8 hours to reach the Moore Haven lock, which we would reach around 3:30 PM. Then we would tie up along the wall at Moore Haven for the evening. There's nothing in Moore Haven except for a good deal on dockage ($63 for the night). The following day, Wednesday, we would run to Fort Myers or Captiva where we would spend another night. Finally, on Thursday, we would reach Sarasota at three in the afternoon.

As readers know, I hate sitting at the dock overnight when the forecast is for favorable weather, which on Sunday evening was the case. We had a four day weather window that predicted low winds and seas under 2 feet all the way to Sarasota.

So now the question was whether to go around the Florida Keys, cut north just west of Marathon at the Seven Mile Bridge and head north to Sarasota. Measuring from Stuart, that adds 160 nautical miles to the trip for a total distance of 360 nautical miles. The extra 160 nautical miles adds approximately 20 hours of running time and $450 of fuel costs. On the other hand, running the Okeechobee Waterway route comes with between $420 to $640 of dockage expense depending on where you stop. Hence there is no cost differential.

The primary consideration is navigation around the keys. Here there are three options, run outside the reef and buck the Gulf Stream, run the Hawk Channel between the Keys and the deep water outside the reef, or run the shallow intracoastal waterway north of the Keys. Needless to say the choice is obvious. The Hawk Channel from Miami to Marathon provides depth of 12 to 20 plus feet and a wide very well marked channel totally suited for night running, especially for a yacht equipped with night vision.

We passed the Stuart Inlet at 5:41 PM on Monday and headed south reaching:
  • Miami on Tuesday at 3:09 AM
  • Marathon Seven Mile Bridge on Tuesday at 2:10 PM
  • Marco Island on Wednesday at 12:46 AM
  • Boca Grande Inlet on Wednesday at 7:11 AM
  • Venice Inlet on Wednesday at 10:31 AM
  • Marina Jack on Wednesday at 12:50 PM
The run from Jacksonville to Sarasota
The final consideration was the approach to Sarasota. Here too there are three options. Big Pass, New Pass and the ICW from Venice north to Sarasota. A call to Sea Tow for some local knowledge was in order, especially since Sarasota Yacht Club had ceased publishing waypoint data for the approach to Big Pass. Sea Tow informed me that New Pass was closed, which was not surprising, and the advice, well founded, to traverse Big Pass at high tide. Since we would arrive at dead low tide the decision was easy. We arrived at the Venice Inlet at 10:31 AM and headed north on the ICW. The only challenge on this leg is four bridges, two of which open on command, and two at fixed times. 

The run from the Venice Inlet to Marina Jack took 2 hours and 20 minutes. We arrived at Marina Jack at 12:50 PM ending a 580 nautical mile run. The average speed from the dock at Morningstar Star Marina in Jacksonville to Sarasota was 8.7 knots. The total time on leg 2 was 55 hours and 9 minutes. Another record.

Approaching Marina Jack
Total miles upon arrival at Marina Jack was 1,517 nautical miles. Even though the run around Florida added 160 nautical miles to the trip, the saving achieved by straight line runs on leg one resulted in an increase distance of only 67 miles.

Bottom Line: This years' trip south was accomplished in 7 days and 7 hours, an ALL TIME RECORD and one not likely to be repeated. The average speed was 8.8 knots. This represents a 0.4 knot increase over the 63's optimum cruise speed of 8.4 knots. While that may not sound like much, it is when the gain is multiplied by 174 hours of running time.

Southbound 2017: What a Difference a Day Makes

This is the first in a series of articles chronicling our annual trip south to our Sarasota winter haven. It starts with weather, most important consideration.

A little background. The United States Weather Service (www.weather.gov) only provides weather forecasts for 6 days out.  Hence, a week before our official November 1 departure, I start to focus intently on conditions. At that point, the only useful data is for October 31, and that data is highly subject to change. NOAA does a great job and over the years their forecasts have become more and more reliable. The science seems to be improving.

This year, the forecast did not look good. There was a tropical depression in Central America that was predicted to become a tropical storm and perhaps a hurricane. The predicted track, after the storm moved offshore, took it over Cuba and then south Florida. That track increased the potential that the storm might follow the coast to New England, and at one point, NOAA had the storm pointed directly at Massachusetts. Not good.

From there the weather story gets worse. As the week leading to departure progressed, NOAA was predicting a very deep (i.e., tropical storm deep) low forming southeast of New York. That low was predicted to track north slowly into northern New England and then into Canada. Powerful 25 to 30 knot southeast winds with gusts to 60 were forecasted for Sunday at Hingham. 

Monday’s forecast called for a frontal passage in the morning with strong sustained winds out of the west, with again, 60 knot gusts. Forecast for the coastal waters south of Buzzards Bay along the south shore of Long Island were for 15 to 20 foot seas. Additionally, high winds were predicted for Tuesday with high seas along our route diminishing toward evening. This did not bode well for a Wednesday 6:00 AM departure even though NOAA was predicting calm winds.

NOAA got it right, literally to the hour. Sunday we saw sustained southeast winds as predicted and gusts to 40 knots. Monday saw the frontal passage at 10:00 AM with 50 knot gusts and a 12 degree temperature drop.  Tuesday was breezy. Then we woke up Wednesday to calm winds and flat seas.

Now to the tropical depression lingering on the east coast of Central America. It freed itself from the mountains, accelerated to 40 knots and became tropical Phillipe. It then tracked north to Cuba and then out to the Bahamas and finally out to sea just south of Florida, where it died. Threat eliminated.

With the deep low far north and Tropical Storm Phillipe no longer a factor, a weather window opened up along the entire east coast. We departed Hingham at 5:42 AM on Wednesday, hit the Cape Cod Canal at 11:09 AM with a favorable 4 knot current, and then reached Wings Neck at the west end of Buzzards Bay at 2:40 PM. A glorious cruise on flat water.

Decision time. Should we proceed south along the coast to our Morehead City destination, some 643 nautical miles south, or take a straight shot from Wings Neck to Cape Hatteras’ Diamond Shoal, a distance of 431 nautical miles and then another straight shot to Cape Lookout and then on into Morehead City? Drawing the straight lines knocks approximately 6 hours off the trip. That represents approximately 50 nautical miles and 54 gallons of fuel saved.

The direct line option takes us over 100 miles off the coast for over two days. This option requires a favorable offshore forecast, the right equipment, a well maintained boat and a crew comfortable with an element of calculated risk. Those of you who follow this blog know that equipment and maintenance are not an issue. So now it come down to weather and crew.

This year’s crew consists of Captain Guy Aries and my friend Jim Eisenhauer. Guy has made three trips with me (Nov 2015, Nov 2016 and May 2017). He’s experienced the full range of cruising situations from calm seas to raging storms. Jim is new to the experience but a fast learner. Again, as readers know, I fully discuss weather considerations and associated risks and make go/no-go decisions democratically.

The weather forecast for the offshore waters between Montauk Point (Long Island New York) and Cape Hatteras showed 2 to 4 foot seas with a worst case of 3 to 5 footers and winds from a low to 5 knots to a high of 20 knots. Most important, no storms were in the forecast through Monday. Given that we would reach Morehead City on Saturday morning we had a two day margin of error. Our decision. Let’s go for it.

Again NOAA’s forecast was dead-on accurate.  On Wednesday night we saw seas reach four feet and then subside on Thursday afternoon.  The result was smoothest ride I’ve ever experienced in the four years and seven runs up and down the east coast.  We witnessed beautiful sunsets and sunrises and mostly smooth seas.  What a pleasure.

We arrived at Cape Hatteras’ Diamond Shoal on flat water at 4:56 PM on Friday. That is a rare occurrence.

All is not gold that glitters. The time savings had a consequence. It resulted in our arriving into Morehead City at 3:00 AM. Fuel docks usually open at 8:00 AM. Hence, we would have “blown” our entire time savings sitting on their dock. Not efficient.

Decision time again. Do we sit at the Morehead City dock or continue further south? For me this is always an easy decision. Why waste good weather sitting at a dock? You know that eventually it will change for the worst.

This time the decision was easy. We already had a forecasted two day favorable weather margin and that situation had not changed. NOAA was now predicting northeast winds with 3 to 5 foot seas all the way to Florida. That that translated for us into a following sea with a tail wind.

We also had more than enough fuel. On Friday afternoon I had transferred 248 gallons to the main tanks. Adding that to the fuel remaining resulted in 735 gallons of fuel on board, with better than 95% usable (based on actual experience during the record 2017 run north in May) we easily had 695 gallons of usable fuel.

Next concern. Where to get fuel? This is actually a tricky question. Yes, there are plenty of fuel stops on the way to Florida but some, like Georgetown, where fuel is incredibly cheap, are way off the beaten path (i.e., add 2 hours of travel time to reach the marina, 2 hours to fuel and 2 hours to return to our course). Others are eliminated by time. We have to arrive during business hours if we want fuel. And, finally, there is the fuel cost consideration. Some marinas think their fuel is very valuable and charge accordingly. For example, I saved over $1,300 this June between the price at Rose Marine and the local marinas in Hingham ($2.00 versus $3.29 per gallon).

Fernandina Beach Florida to the rescue. Its 400 nautical miles from Cape Hatteras, well within our remaining usable fuel range (including generator use), easy in and easy out, and its fuel is reasonably priced.

IMPORTANT NOTE: The weather window to the north had already closed when we reached Cape Hatteras.

Before I continue, let me briefly highlight our incredible 5.5 day journey (using military time):
  • Wednesday 05:41 depart Hingham
  • Wednesday 11:09 arrive at the Cape Cod Canal - zip through canal at 12 knots
  • Wednesday 14:40 arrive west end of Buzzards Bay - straight line to Cape Hatteras
  • Friday 16:56 arrive at Cape Hatteras's diamond Shoal - straight line to Cape Lookout
  • Saturday 00:36 arrive at Cape Lookout - straight line to Cape Fear
  • Saturday 09:49 arrive at Cape fear - straight line to Fernandina Beach
  • Sunday 12:46 arrive at Fernandina Beach Inlet - straight line to St John's River Inlet
We make a straight line down the coast. A first
Approaching St Mary's Inlet and the Fernandina Beach Municipal Marina
At 12:46 PM we turned southwest into the St Mary’s River and called the Fernandina Beach Municipal Marina to alert them of our intention to take on fuel and our arrival time. Oops. Big Surprise! The dockmaster informed me that they had “still” no fuel thanks to Hurricane Matthew (September 2016).   The dockmaster stated that Port Consolidated had fuel but they were closed on Sunday. When I asked if we could stay the night he informed me the Matthew had destroyed their face dock and that besides being “no room at the inn” there was not enough depth for the 63’s five foot draft.

This posed a bit of a problem. A quick check of the site glass on our tanks showed fuel remaining of 290 gallons, with 250 usable based on experience. That translates into an absolute range of 250 nautical miles. So while the situation is not desperate, it did suggest that we find fuel close by or anchor out at Fernandina.

Fortunately, the St John’s river approach to Jacksonville was 20 nautical miles south and there are several marina’s just west of the inlet (read as easy in easy out) and, most important, Morningstar Marina, the first one we called, had fuel and dock space. Time for a course change.
We pulled into Morningstar Marina – Mayport at 3:46 PM, took on 1,105 gallons of fuel at $2.79 per gallon ($3097.71), and in two hours we were back on the road.

This trip set new records:

Longest distance: 936 nautical miles (previous 766 NM – Spring 2017)
Fastest average speed: 8.8 knots
Longest passage: 5.5 days and 4 nights (previous 4 days and 3 nights – Spring 2017)
Longest passage without rough weather
Longest running time: 107 continuous hours
Distance from shore: Over 100 miles
Time without phone or internet connectivity (Wednesday evening to Sunday afternoon)
1
Factors that contributed to the unusually fast average speed of 8.8 knots
1) The Labrador Current (track from Buzzards Bay to Cape Hatteras
2) We close to the coast and west of the Gulf Stream'
3) A low pressure trough east of Florida and parallel to the coast set up the northeast winds
All trips should be so easy.

Stay tuned. We’re about to break another record.

PS. Yes, we had some adventures and those will be the subject of the next few articles.
