When I purchased new sails for Terrapin, I also bought a spinnaker. The spinnaker is used for downwind sailing when the wind is between 90 and 180 degrees off the bow. Paradoxically dead downwind sailing or “a run” is generally one of the slowest points of sail, mainly because you are relying on your sails to be “pushed” by the wind directly behind them. Conventional main and jib are not really designed for this. Instead, conventional sails are designed to be a curved airfoil, like a vertical airplane wing. The wind passing over the front of the sail provides “forward lift” and propels the boat forward. In some cases, this can propel the boat faster than the wind speed as in the recent Americas Cup catamarans. The spinnaker is a large light balloon like sail that catches the maximum amount of wind from behind to improve downwind sailing performance. It is generally used for light wind of less than 15 knots.
The spinnaker is also somewhat tricky to rig and deploy and I had no experience with them other than reading and watching YouTube videos. We have been on several stretches of long downwind sailing on Terrapin during our recent cruise to the Keys and have been frustrated with the slow speed. Finally, one day I decided to test out the new spinnaker. I think I made every mistake in the book and paid the price. With Laura at the helm, I went to the bow and pulled the spinnaker out of the bow locker. It is in a rather large bag and pretty unwieldly. I hooked it up to a bridle that ran from one bow to the other with a shackle to attach to one of the lower corners of the spinnaker, called the tack. The other lower corner of the spinnaker is called the clew and is where you attach the sheet that runs to the cockpit on the leeward side and controls the shape of the sail. By adjusting both the bridle position side to side and the sheet, I can control the position of the spinnaker and the amount of “ballooning”, or so goes the theory. The spinnaker is in a sock about 40’ long and designed to be raised and unfurled in two steps: 1. Attach the head of the sail to the spinnaker halyard and hoist it up to the top of the mast. 2. Pull on another line running from a cuff around the bottom of the sock to the top of the spinnaker and then back down again. Pulling on this line raises the sock and allows the lightweight nylon spinnaker to unfurl and catch the wind. To douse the spinnaker, you pull the sock back down with the same line. So, I hooked up the tack and clew and raised the sock on the halyard. So far so good. Except that by the time I had done all this, the wind speed had increased to about 15k, gusting to 20. I should have stopped right there. Hindsight is 20/20, right? Well, I raised the sock and all hell broke loose. The sheet running to the cockpit wasn’t secured and came loose, allowing the spinnaker to flap uncontrollably in the strong wind. It started to wrap around the forestay where the genoa is rolled up on a roller furler. I had also left the two genoa sheets attached to the genoa and these quickly became tangled with the spinnaker lines. I tried to bring the sock down but it was jammed. I spent what seemed like an eternity trying to control this crazy flapping spinnaker, but it was probably about 10 minutes. I finally went to the mast and lowered the halyard lowering the whole mess to the trampoline. Exhausted.
- Don’t try to fly the spinnaker in wind stronger than 15 knots, at least until you have plenty of experience.
- Attach the sheet and tack more securely.
- Make absolutely sure the sock is free and clear of all lines and on the proper (leeward) side the forestay.
- Remove the genoa or jib sheets so there is no chance of getting tangled
- Clear the deck of all stuff, fenders, docklines, etc.
- Practice with raising the spinnaker at the dock before attempting to use it under sail.
Well, after digesting and re-enacting the scenario in my mind, I finally got the courage to try it again when we were sailing downwind in much lighter wind. This time it worked perfectly! What a good feeling to pull up the sock and see this beautiful sail catch the wind and feel the boat accelerate.
Flying the spinnaker on Terrapin
Downwind sailing under spinnaker alone
Like last year, I plan on flying down to Punta Gorda mid-summer to check on Terrapin and do a few maintenance items so we won’t have as much to do in November when we want to go sailing. The number one priority before splashing Terrapin in November is to remove all traces of barnacles on the bottom, the prop shaft and propellers. Then put on another coat of bottom paint. Bottom paint on boats is a whole science/art in itself. Most boats in warm tropical waters have some sort of soft ablative paint. The ablative material is usually copper suspended in the paint. I’m talking a lot of copper! The copper is supposed to retard growth of marine organisms on the bottom, but it is only a partial solution. The other property is the fact that the paint is soft, particularly when it is wet. This allows the paint to slowly sluff off over the season when the boat is sailed or when scrubbed with a pad. So, bottom line is that there will be some bare spots on the leading edge of the hulls and keels that will need touching up. So, I plan to spend a few days scraping barnacles and touching up the bottom paint. It’s also a good opportunity to check that there is no water leaking inside or bugs. Last year, we had a few ants in the cockpit and some wasps making a home in the boom, but nothing terrible.
I will also be checking on the batteries. Terrapin has four deep cycle golf cart type batteries to serve as the house bank, and two starting batteries for starting the diesels. Lead acid batteries do not like to sit for long periods of time without being charged as they will self –discharge and go dead after a while. Terrapin has a 145W solar panel and a charge controller that monitors battery voltage and delivers the proper charge from the solar panel. Last year, this worked perfectly and kept the house bank fully charged. However, the solar was not hooked up to the starting batteries and they had lost quite a bit of charge over the summer. This summer, I hooked up jumper cables to the start batteries so they should also be charged by the solar panel. We will see how they look. I will have another separate post about battery charging.
It is now the beginning of August, 2018 and our commuter cruiser lifestyle is going according to plan. Terrapin is once again tied down on the hard in Safe Cove Boat Storage in Charlotte Harbor, FL. Laura and I are back in Lexington and enjoying our work, knowing that we will be back sailing in November. We had Terrapin hauled in mid-April and then lived aboard on the hard while we got her ready to weather the six months in the southern Florida heat, sun and rain. The first step after hauling was to have the yard guys pressure wash the bottom. Terrapin had been in the water for 6 months and we had been sailing for about 3 months during that time. The more you sail, the cleaner the bottom stays. But a month sitting in the marina is plenty of time for all kinds of marine growth to accumulate on the bottom, from easy to remove algae/fuzz to PITA to remove barnacles. I had the bottom cleaned by a diver twice, but there were still quite a bit of barnacles on the bottom and the props. Most were removed by pressure washing and scraping, but there are still plenty remaining on the boat.
For those who are interested in commuter cruising, here is our checklist for prepping Terrapin for storage. Unless you want to pay someone to do everything, you can’t just drop the boat off and wave goodbye. If you want to protect your investment and have a boat that will be ready to sail in the fall, there is a substantial amount of work prepping the boat for storage. For some, this could be a deal-killer. For us, it was a labor of love.
Heading north up the west coast of Florida we were planning on stopping for the night in Marco Island, the same place we stopped coming south a few weeks ago. But then we noticed a small anchorage just south of Marco in a shallow area off Cape Romano. We decided to give it a try. Wow, it turned out to be one of our more memorable anchorages. There is a large exposed sandbar called Second Chance Sandbar. The area is constantly shifting and we had to maneuver very carefully watching our depth gauge. We ended up anchoring close to the Second Chance sandbar but we were way out in the middle of a very large bay with gorgeous views 360 degrees. Second Chance Sandbar turned out to be a “CWA” or Critical Wildlife Area that is a nesting habitat for a variety of seabirds. The other interesting feature of this area is a group of bizarre looking dome houses out in the water that look like they are right out of a Star Wars movie. For an interesting read, Google Cape Romano Dome House and read the Wikipedia page. They were built in the 1980’s as a vacation residence on a small island, but they have been abandoned since the 90’s and the rising sea level is now taking them back.

We haven’t seen a lot of dolphins on this trip but we finally got a bit of a show one afternoon while anchored off of Chino Island, just off the ICW north of Sanibel Island. There was a group and they were circling around schools of fish in a typical dolphin feeding behavior. I grabbed my camera and managed to get a few shots.

The J. N. “Ding” Darling National Wildlife Refuge is part of the United States National Wildlife Refuge System, located in southwestern Florida, on Sanibel Island in the Gulf of Mexico. It is named for the cartoonist Jay Norwood “Ding” Darling. You can access it by land from Sanibel Island, but the most extensive part of the refuge is a large expanse of shallow waterways and lagoons which provide habitat for a large number of aquatic birds. We anchored just off the eastern edge of Sanibel Island and took the dinghy into the maze of canals in about 2 feet of water. I brought my new Olympus OMD E-M1 Mark II with a 300mm f4 IS Pro lens to try it out for bird photography. Here are a few examples.

Boot Key to Shark River
The wind was predicted to shift around coming out of the south for the next few days, so we decided this would be a perfect weather window to head back north from the Keys. It was also a good weather window to head to the Bahamas and our friends Randy and Rose on Contessa Rosa were planning on doing just that. We wished we were also going to the Bahamas, but we need to get the boat in storage by April 15th or so. The sail up to Shark River was great. We had about 15-20 knot winds from our stern and following seas. We sailed most of the way with our sails “wing on wing” with the main let out to port and the genna to starboard. The only negative were the bugs in Shark River. Once the sun went down, we needed to get inside the boat and put screens on all the hatches.
Back Boot Key Harbor
We decided to go back to Boot Key Harbor for a few days and get ready for the sail north to Punta Gorda. We like Boot Key Harbor a lot: super friendly boating community, mooring balls are reasonable at $18.00 a night, the City Marina has good showers and services, and there are lots of businesses close by, like Publix and West Marine. I worked on some wiring projects on Terrapin, we went to Sombrero Beach, and we ate some great seafood at Keys Fisheries.
The weather forecasts all said that the weather would be perfect for sailing across the Florida Bay from Shark River inlet on the lower part of the Florida Mainland to Vaca Key, the middle of the keys where the city of Marathon and Boot Key Harbor is located. The wind was predicted to be 15-20 knots out of the east and we were headed due south. This would put us on a beam reach on a port tack. The Florida Bay is a huge bay made up of the Florida Keys archipelago extending south from the southeast tip of Florida then curving to the west, about 25 miles across from the tip of Florida to Vaca Key. One of the noteworthy features is that the entire bay is shallow, only 10-12 feet deep. That means that the effect of the wind on building waves is magnified significantly. We are used to sailing in deep Caribbean waters in 15-20 knot winds and the sea state is generally mild with long rolling swells. What we discovered in the Bay of Florida was a steep chop of increased period. That made for a bit of an uncomfortable ride. In addition, the wind ended up being 20-30 knots instead of 15-20. So, we found ourselves sailing a beam reach in 20-30 knot winds with fairly rough seas, with boat speeds of 8-10 knots. When I realized the wind speed was that high, I reefed both sails (reducing the sail area) and tried to set a relatively comfortable course, doing a bit of a zig-zag to keep the waves from hitting us directly on the beam.
The other thing we had to deal with was that the bay is full of lobster/crab pots. Fisherman lower the metal trap with a small buoy attached by a rope. If you run over them, the rope can snag on your prop, or rudder. We have dealt with these all over, including the Caribbean, but the effect of the wave chop was that we had a very hard time seeing them in time to avoid them. Well, you guessed it, we snagged not one, but three pots. We were sailing along at 9 knots and all of the sudden we slowed down to 4. I guessed we had snagged a pot, but couldn’t see anything from the deck. So, we dropped the anchor and I went in the water with my mask, snorkel and fins and life vest tied to a line attached to the boat. Sure enough, the starboard prop had not one, but three lobster pot buoys snagged. I was able to unwrap them and set Terrapin free. This delayed our trip about an hour and a half but we still made it into Boot Key Harbor in daylight.
Lobster pots are a real problem in this area. They are everywhere. You have to be on constant watch while sailing or motoring. Nautical charts and books refer to all sorts of “hazards of navigation” but of course there is no charting of where lobster pots are and there are no apparent regulations for where they can be placed. You find them right in the middle of entrances to harbors and well-marked waterways. In fact, the pots probably represent the biggest hazards to navigation as they have the potential of disabling your boat. If your boat is disabled in rough seas near the coast line you could end up on the rocks. Most regulations on the books protect the lobster/crab fisherman. It is a felony to tamper with these pots. However, there needs to be some sensible regulation on where these pots can be placed. At least have some corridors where pots are prohibited so boats and the lobster industry can co-exist.
These guys look harmless, right?
You can count eight pots in this picture.
We are anchored off Bahia Honda State Park inside the old railroad trestle that is now a National Historic monument. The section that is open was removed so sailboats could get inside the bay.
