Canaveral to Key West

“Mile Marker” Zero?

We made it to Key West, a milestone of sorts. We are here for a month or so and will celebrate Christmas with our two sons. Then it is off to the Bahamas.

The leg from Canaveral to Key West was relaxed as we had time to kill before our slip reservation at Boca Chica Marina near Key West. Our first night out promised to be lumpy with strong winds out of the North so we chose Suntex Marina (formerly Loggerhead) in Vero Beach. We had never been there and were somewhat concerned about the channel as there were numerous Active Captain comments about hard obstructions in or near the channel. All I can say is that we had no issues and I would estimate at least 6′ at low tide. Once inside, the marina was very nice and totally protected.

We followed up with some locals regarding the channel and one fellow provided us a set of soundings that he had taken with his dinghy. Those soundings did show some shoal area encroaching on a portion of the channel, not quite reaching the centerline. I am sure those write-ups in AC were true, in that the boats hit something, but maybe not so accurate in that whetever they hit, it was not on centerline. We left the next morning following our breadrumbs from the day before without any problems.

The charts show just a few pilings but there are actually 8-10 on each side of the channel so it isnt that hard to stay centered. If anyone wants a copy of the soundings for the channel, send me an email.

A note on Active Captain. I read the reviews and check the hazzard comments on my route, but often the hazzards just arent there. All I can figure is that the authors just werent where they thought they were when they encountered the problem. As best I can tell, nobody reviews the data and once a hazard is logged, it stays on the charts forever, despite numerous comments that the hazard just isnt there. More on this later.

Our next stop was Peck Lake. This is another interesting spot becasue the charts show the area to be 3-5′ deep when there is a large area 10′ or greater. But the only way to figure out just how large the area is requires probing with your hull. Not my favorite. In this case, the AC comments are helpful as they describe where the “gate” is as you leave the ICW and enter the anchorage.

For us it was fairly easy because there were just a few boats there. We picked a spot with plenty of swing room and felt a good set on the anchor. By the way, you know how a dog circles his spot before lying down? I understand that is to insure he doesnt cover a gopher hole or whatever. Well the same sort of move works with a boat. If we arent sure we will have minimum depth throughout our predicted swing we will circle our spot to confirm, doggy style.

It looked like a fine evening, until the bugs arrived. And did they ever. By morning we were covered in bugs that looked sort of like mosquitoes but didn’t bite. They just left stains everywhere. And they stayed with us for days. What a mess.

Lake Worth inlet and anchoring options

Our next stop was Lake Worth to an anchorage just south of the inlet. There are three options for anchoring here. Just south of the inlet, at the northern most AC symbol, you can anchor just south of the channel. It is close if you want to enter or leave in the dark. But the current is strong and it is quite deep at 20′ or so. The next spot, just south of the large spoil area, is close to the inlet but somewhat crowded with a mix of moored and anchored boats. Further south, roughly east of Rybovich Marina, is 1.7 miles from the inlet but wide open. We chose this spot and had a pleasant night.

We left the next morning just before sunrise. There is added light from land so not so hard to leave in the dark and run along the docks to the inlet. Lucky for us, the weather was perfect for an outside run to Miami, skipping the most concentrated series of bridges along the Florida coast.

Venetian Islands Anchorage

We have anchored here a few times. Well protected but can be busy with tour boats, jet skis and the like. Better on weekdays. There are a couple of No Anchor spots as well. Under current Florida anchoring laws there are very few places you cannot anchor. These are some of them. The houses here are all million dollar plus and the rumor is, a few have enough political pull to prevent boats from disturbing their views. Whatever, still plenty of places to anchor that are out of the way of traffic and protected. Last year we anchored between San Marino and Di Lido, this year just SE of Palm. A good place to wait on a hop east to the Bahamas or, in our case, south to the Keys.

Our plan was to stay inside Biscayne Bay to Anglefish Creek, then go out to Hawk Channel for the rest of the trip to Key West.

Anglefish Creek

Anglefish Creek is one of the last places a boat drawing 5′ or more can exit to Hawk Channel. The ICW continues but there are large portions where the depth is less than 5′, especially at anything but high tide. But reading the AC comments about the creek suggests there are areas of less than 5′ in the channel as well as hidden obstructions. Here is another example where blind allegiance to AC comments will keep you from going places that are safe.

Since we had a few days to kill, waiting on weather, I took the dinghy out and sounded the entire creek. I also talked with numerous boats passing through the creek in both directions. From my readings the lowest points are at the entrance and exit from the creek. On the Biscayne Bay side, the lowest point is 7′ MLLW and on the Hawk channel side, 6’3′. And I could not find any obstruction between marks 1 and 3 as AC described. I did chat with the author of the AC obstruction comment and I am sure he really did hit something at that point, but my guess is, it was some sort of partially sunk log that had since drifted off.

Our first time in Hawk Channel. My two comments; the barrier reef does cut the swell from the east, but doesn’t really help with the wind driven wave. And the number of crab floats will keep you paying close attention to your path through the mine field.

There are not a lot of anchorages with much protection from anything above 15 knots from the east so a run down Hawk channel requires a bit of weather planning. There are only a few bridges that will allow a cross over to the other side of the Keys in order to get out of wind or wave. We anchored one night on the far side of Channel Five Bridge and then went to a marina in Marathon to avoid a cold front.

WE spent a few days at Marathon Marina and Resort, just inside the channel into Boot Key Harbor. A very nice marina that is cruiser friendly and has decent rates for extended stays. Marathon served our purposes well but we had a hard time appreciating the attraction to the mooring field in Boot Key Harbor. Hundreds of boats here, many for the season. Nice weather, good protection and cheap rates, but not particularly attractive. And it is hard to fall in love with the town of Marathon itself.

We did enjoy a tour of the Turtle Hospital in Marathon, which is a real working turtle rehabilitation facility. Tours are a little pricey at $25 or so, but since the proceeds are important to funding their work, then maybe not so bad. We also checked out the bars in the area and give two thumbs up to the french fries at Burdine’s.

We next headed to Boca Chica and our marina for a month. Boca Chica is home to Key West Naval station airfield and an MWR marina. The marina was a mess after the last hurricane, with many boats sunk in their slips, but now it is up and running and nearly full. Not all repairs are complete but it is in pretty good shape. Tiki bar, small restaurant, beach, etc. And $1/ft. But only for military.

We are about seven miles from old town Key West, so having a car is helpful. We have been doing the tourist things in town, and it is a touristy town, but it is also a town with plenty of legitimate history if you look past the Tee shirt shops on Duval street. Maybe a dedicated blog post on Key West in the future.

The boys are both here for Christmas so their christmas present was a day of deep sea fishing. Fishing is a big deal here, with hundreds of charter boats available so choosing one boat was a challenge. We did a lot of internet searching but finally settled on a boat we had seen arriving at the dock by our happy hour bar. Among the six boats at the dock, this boat had the most fish. We chatted up the captain and liked him and hired he and his deck hand for the day before christmas. The boat name was Triple Time and I would recommend it. An older boat but a great crew. And of the returning boats, we had the biggest catch.

The catch

We caught all five tuna in about an hour. None before or after. Other boats that missed the window got nothing. Our captain said he had been doing this for 40 years so I am guessing our success was not just luck. The biggest tune weighed in at 25 lbs. We are still eating it.

We would have had one more tuna but a shark beat us to it.

Mobjack and maintenance. ICW next

Have been a bit slow to update of late. We are currently at Zimmerman Marine on the East River in Mobjack Bay. Getting a little warranty work completed before we head off to wherever.

By the way, the current location button isnt working just now. It is tied to our Iridium sat phone and we have not energized the SIM card as of yet. Soon.

Nothing particularly impressive to report. East river was not too busy. We transited on a weekend (bad) but early in the morning (less bad). Jersey coast overnight was benign and we hit the current pretty well so were able to make it from Port Washington to Fairview Marina just south of Baltimore in one overnight.

Krogen Rendezvous in Solomons was fun, as usual. We then took a trip up the Potomac to DC. The trip up the river was fine, but the amount of debris in the river was bothersome. We only hit the logs we couldn’t see. And there were plenty of them.

We spent a week at Capital Yacht Club in the Washington Channel. A very nice facility with very friendly staff, members and fellow cruisers. Wore ourselves out museum hopping. The highlight was the Library of Congress. Who knew?

Our son, Evan and his girl friend spent a day with us and we enjoyed playing tourist. Attended a gala at the Kennedy center, the Mark Twain award for comedy being awarded to Julia Louise Dreyfus. Toasts from the likes of Steven Colbert, Jerry Seinfeld, Tina Fey, etc.

The trip south on the Potomac was much better as most of the debris was blown out of the river by the cold fronts that passed through while we were snug in our slip in DC.

Had occasion to anchor out a number of times in the Chesapeake, always a treat. Now at Zimmerman, we hope to leave tomorrow morning and go as least as far as Norfolk and Mile 1 of the ICW. Plan is to get to Cape Fear, then wait for a window for an overnight run to Charleston. We will keep you posted.

Measuring Electrical Draw – Boat Power Management

We anchor out a lot and I hate running the genset so anything I can do to reduce our power requirements is of interest to me. The first step in reducing power is determining where the power is going. One can get an approximate measure of power draw by watching the panel and turning devices on and off. That works OK for lights and pumps, etc, but it gets a little more difficult for refrigeration systems that cycle on and off.

A more accurate approach to measuring current draw is to install a plug-in meter between the outlet and the appliance. Some of the meters available to consumers are pretty sophisticated, allowing for the download of data to a computer for analysis. But if you cannot easily reach an AC outlet, or the system you want to monitor is hard-wired, be it AC or DC, then the options for monitoring consumption over extended time periods are fewer.

. Our fridge and freezer are stand-alone AC powered Sub-Zero drawer systems. They are installed such that the wiring is inaccessible. So I went off in search of a device that could record current draw by accessing the wiring within the electrical panel. I found a device at EKM Metering, which supplies commercial grade systems to industry. Overkill for my little project but all I could find.

I wired this device into my electrical panel. The first time I did it for the fridge and it took my two hours. The instructions are fine but written for an electrician, which I am not. When I did it again for the freezer it only took 15 minutes. The device, peripherals and software costs about $300. It connects to a laptop via USB and provides real time monitoring to whatever level of detail you select.  Below is a screen shot of the real-time data showing the power draw as the freezer cycles on and off.

The data can be downloaded to excel for analysis. I ran the system for 24 hours for the fridge and again for the freezer.

Here is a portion of the data available from the device. I captured a reading every 60 seconds. To analyze the data I used the number of minutes the system was running and the amp draw while running.

Both compressors cycle on every 15-20 minutes and run for 12-15 minutes. The freezer runs more often and draws a little more when it does run. I was pleasantly surprised that they drew as little power as they did, at least when it is cool outside. I will run the test again in the Bahamas where the temperatures are in the low 80’s.

At anchor in the Bahamas we consume approximately 250 amps per day. Of that, the combined draw of the fridge and freezer accounts for 38 amps (measured here in cool RI). My guess is, in the Bahamas the fridge/freezer draw will be double that or 76A. If that is close, then I will have to figure out where all the other current is flowing.

 

 

Lightning Protection- Short Note

We are currently hauled at Bristol Marine in Somerset MA having a lightning protection, or more accurately, a lightning survival system installed.

A little background here. In our sailing days we encountered lightning more often than I would like, usually when crossing the gulf stream. We were never hit although on one particularly unpleasant night we had multiple lightning strikes to the water within yards of our sailboat.

Getting hit by lighting on any boat while at sea could be disastrous. people can die and boats can sink from all the holes blown out at and below the waterline as the current passes through the boat and into the water. But the more likely result of a strike at sea would be the loss of all electronics. If that happened to me while on a sailboat I would be pretty confident I coud sail to the nearest port with no more than a hand-held compass and a paper chart. But the key word here is “sail”, meaning I could keep moving in the general direction of land.

For me, the biggest impact of moving from sail to power is the dependence on the continuous operation of multiple boat systems; electronically controlled propulsion, electric throttle controls, electrically managed hydraulic stabilizers, etc. If we were to receive a lightning strike at sea it could be rather devastating. No “sailing” to the nearest port, just bobbing around at the mercy of the sea until rescued. By who?

When we brought the boat up from Florida last spring we stayed in the gulf stream for four days. And that is just asking to be hit by lightning! As it turned out, we only encountered one active convective storm and we were able to avoid it. But I know from my sailing days that is not always possible. Once clear of the storm I got to asking myself just what we would do if we did get a strike that knocked out most of our systems.  I realized that we were not prepared for this. So we had a few choices; stay inland, continue our offshore runs and take our chances, or find some way to better prepare and protect the boat in case of a lightning strike at sea.

We chose option three and have made two significant changes to the boat. First, we added a sea anchor to our suite of safety gear. If we were to loose engine power we can now at least keep the boat to weather until help arrives. And we are adding a lightning protection system.

My research into the subject of lightning protection for boats identified a few things. One, protection systems are as much art as science, and two, the currently recommended systems consisting of a lightning rod on the mast and grounding cables to a below waterline plate, don’t provide the sort of protection for on-board electronics that I was looking for. Most lightning strikes, understandably, happen in marinas. And it is beneficial to try and reduce the amount of damage caused by such strikes. Basic lightning protection systems probably accomplish this. But my goal is not to reduce the cost of repairs after a strike in a marina, I have insurance for that. I am looking for a system that will accept a strike at sea and give my a chance of continuing to run.

Protecting a sailboat versus a power boat provides some different challenges. Sailboats are natural lightning rods. They are also natural Faraday cages if all the standing rigging is tied into a grounding system. This can at least provide a level of protection for the occupants, if not for the electrical systems. Our trawler has a short mast, but from a lightning’s-eye view, our entire boat is one big path to ground. We have at least 12 antennas outside the hull, any of which is fair game. A lightning survival system for us keeps the voltage spike near the outer hull and provides multiple low-impedance routes to sea.

We are working with Dr. Ewen Thomson of Marine Lightning Protection, Inc. He is providing the overall design approach and advising on the details as I incorporate the design goals within the confines of an already built boat. I don’t think there is anyone who knows as much about marine lightning protection as Ewen so it has been fun to work with him. More on all this in the future

This is one of the early sketches we worked from. The design we are installing has evolved from this.

 

As the project progresses I will go into more detail on the design and installation process. Meanwhile, I need to get back to stringing wire in very small spaces.
