November 7 Morehead City to Swansboro 20 4 miles

We headed off in the ICW through Bogue Sound and this is hard work because the sound is so wide and the deep channel so narrow. I ran us into the sand at one point but we dropped the sail and backed off. Yes, I tried to sail, using the small jib only, which gave us an extra knot or two, but the strong gusty wind blew us off the course auto pilot was trying to steer; and with trimming the sail came the inattention that led to the grounding.  So no more sailing today. 
We were underway from 9:30 to 1:30. Most of the way was a few degrees north or south of due west. Ilene called the Coast Guard who told us that the live shelling at Camp Lejeune would end at noon, hours before our arrival, so we could anchor at Mile Hammock Bay. But just a half mile after we passed Swansboro, “Pipe Dream,” which has overtaken us, was coming back the other way and told us that the live firing would continue until 5, too late for us to arrive there. So we too did a “U” turn and anchored in Swansboro.
The pencil is pointing to the white spot to the right of the town, where we are anchored. In the lower left, just below the line "X---X", is a magenta line labelled "St M 230" (Statute Mile 230 since Norfolk), running perpendicular to the double dash bordered magenta line indicating the route of the ICW, which shows how crooked it is. And below the knife blade in the lower right corner it says Bogue Inlet, through which, in the photo below, we saw out to the Atlantic for the first time since Cape May, NJ.
We also saw the dramatic effect of the swift running tide. It was ebbing  and as we came to the Inlet our speed picked up to 6.6 knots, only to drop to 4.2 knots as soon as we passed the inlet when the same outgoing tide was running against us.

Here in Swansboro we  are one of eight boats and are on 80 feet of chain in 17 feet of water. The big factor here is the tide which caused us to face the other way when it changed. We happened to anchor next to “Island Time” and used our dink for the first time on this cruise – I’ve been out a month today! The town is quant but we failed to find a postcard though we did find this Gekko,
made from the steel top of a 55 gallon drum, at a gallery.














This house was built in 1778.

   Here were ashore, our heads framing ILENE.
Tomorrow is a long day to Wrightsville Beach, almost 47 miles. So its early to bed.

April 4 Titusville to Rockhouse Creek New Smyrna 31 2 Miles

Well the good news is that apparently felines have short memories. So Witty is not a permanent victim of Post Traumatic Stress Disorder, but his old pesky self. It was Saturday, the day before Easter, and warm and sunny so EVERYONE was out on the water. We saw hundreds of boats from Stand Up Paddleboards, to kayaks and canoes,







to fishing boats of all sizes,
to what I call motorized rafts.
And people were wading and swimming in the ICW too.

I put out the genoa and later the small jib but the wind was too close to our bow much of the time and too erratic. Anchor to anchor from 9:30 to 3:00. Only two opening bridges, one on request and the other every twenty minutes, which we made easily. The tide helped us the last third of our passage, except the last mile, once we got to Ponce de Leon Inlet, and we turned down the engine to near idle speed to give the watermaker two hours to make water before we arrived. We passed some nice modest waterfront houses
and some waterfront trailer parks also known as fishing camps....I think.

Rockhouse Creek runs east-west, connecting two  N-S waterways. (It is the horizontal in an "H".) When we arrived it was very crowded with perhaps fifty small boats and a few large ones. Folks had gone to the beach. We can only enter from the ICW, western end because it gets too shallow for us at the other end, but many powerboat people think that circumnavigating the unnamed island that forms its south side is a nice trip. We heard five of them comment on ILENEs name as they passed us. We had dropped anchor and settled in and by six p.m. there were only three boats left (one other sail and a trawler)
and we were too close to the sailboat, especially because there was so much room everywhere else and strong winds from the east were expected. So we picked up and dropped 150 feet further away from that sailboat. Our other neighbors were a family of campers.
There was no one on the other side of us, where we would turn right and be back in the ICW.

Im having trouble with the new snubber hook, (as well as the underline function) specifically in getting it to stay hooked onto the anchor chain; it falls off and dangles uselessly under the boat instead of doing its job. I tried tying it on but this wasnt working well so I next tried wrapping one side of the hook with rubbery tape to narrow the slot into which the chain sits, but that fell off. 
Here in Rockhouse, I knew it had fallen off when the wind came up at night: the chain took the load instead of the snubber and when ILENE hunted from side to side, the anchor chain snaps over in the bow roller making a sound like the boat is being pounded by a sledge hammer.

I created a way to mount the red and green dinghy navigation light using a suction cup, a piece of scrap plexiglass, a nut, some washers and a piece of thin line.

We have been noticing that Florida has given nicknames to its geography much as in Manhattan, neighborhoods like SOHO and Tribeca that have no legal or governmental significance  are used to define neighborhoods. The southern part of Florida: Miami, Fort Lauderdale and maybe Boca is called the Gold Coast. Heading north, next comes the Treasure Coast including Palm Springs, Stuart and Fort Pierce, so named because Spanish treasure galleons sank off this part of Florida. Cocoa, Titusville and New Smyrna are called the Space Coast. I hadnt noticed this before.

July 3 4 Parade up NY Harbor with LHermione 60 Miles

The New York Times of July 3 had a full page article on the visit of The Hermione. (We learned that while we pronounce her The Her-my-oh-knee, the French call her LAir-me-own.) A replica of the French square rigged wooden gunboat that ferried Lafayette across the puddle to help us win independence from the Brits. She visited Yorktown VA, where the original boat helped defeat the British resupply and re-enforcement fleet, thus causing General Cornwallis to surrender to General Washington, effectively ending the military aspects of the Revolution. We visited Yorktown on our way south and on our way north. Hermione is doing this as a good will tour, to remind us of our friendship with the French and making stops up the eastern seacoast to Boston. 

As Fleet Captain I put this out as a potential Club adventure and three other members joined us for the parade, though only two of us on  HYC registered boats. My friend since 1972, Marty, joined us at ten a.m. at the Harlem and we got underway at 11. But a failure of communication caused us to spend half an hour, drifting, waiting for "Shanghai," a Pearson 31, the other Harlem boat, with CJ and Jenny, while they had gone ahead. During the wait the NYC police burned off a vast stash of fireworks they had taken.
No problem once communications were restored; we caught up with Shanghai at about 90th Street in the East River, making great speed with the favorable tidal flow and engine.





ILENE, shown here passing 25th St.,used mainsail pretty much the whole way, but the wind was so light that except for a few puffs it mostly just prevented rocking.
 We anchored in Gravesend Bay, off the west end of Coney Island, Brooklyn, On the way we were passed by Gandalf 3, another Saga 43 out of Stamford, which I had visited to study its dinghy davit blocks before connecting ILENEs
Gravesend Bay is huge but exposed. But its very near where the parade was to start and there was very little wind at night, so we anchored out on the flat in 17 feet of water, with 70 feet of snubbed chain. There is a deeper channel, 25 to 27 feet, closer to shore, so we stayed further off. Our new smaller stainless steel snubber hook was deployed and it works like a charm. Finally!
Having left at 11:30, we arrived at 3:00 and lowered the dink. You cant miss the spot, Toys R Us put out a big welcome sign. The boats to the left are among the four French flagged Beneteaus,  Waquies [the key for the last letter of the alphabet is inoperative] and hard chined aluminum sloops "dressed" for the parade with their signal flags. They came in after us and anchored far enough away from us. I had expected more boats.


Then came a few hours rest, except I used the time in an unsuccessful attempt to get the cockpit VHF radio to power up. It is so convenient and useful because VHF Channel 8 was used for communications during the parade, but we had to use the inside radio turned up loud.
A shared dinner aboard ILENE for the five of us: Lene, Roger, Marty and CJ. Thanks for your pictures Jenny!
Everyone had brought food that did not need to be cooked and the menu was varied and delicious, starting with a bottle of champagne and cheese provided by Shanghai. We were together from 6 to 9 before I dinked CJ and Jenny back to Shanghai and everyone had a good nights sleep. Jenny, became infatuated with our cats, and can you blame her.











Sunset under the bridge:
In the morning, mango- sweetpotato pancakes were on the agenda, sweetened by honey that we had, and peanut butter that Jenny brought, not that the pancakes really needed to be sweetened much. And I forgot the bacon as well as the maple syrup! And the final system to seemingly go down was the fresh water pump. I can hear it run but it is not bringing water to the tap. So the dishes were rinsed off in a bucket of soapy seawater and will be properly washed once order is restored.

The parade formed up: about a hundred boats at its peak, all at the sides and rear of Hermione once she turned at the start.
I felt bad that I had not yet purchased a new American flag and flagpole after ours went missing during our winter excursion. But marty wore a sweater during the parade which eased my guilt.

The leader had a fetish about arriving under the Veransano Bridge, and at the Statue of Liberty, at precisely pre-scheduled times
presumably for the coordination of a US Navy flyover by two jets, for the media and for fire boat blasts, center in next photo.
But this caused me problems because Hermione did not maintain the five knots speed over ground that had been the plan and was repeated via VHF. I had only the small jib up and engine but it is hard to go straight when you slow down to 1.8 knots and when boats are perhaps fifteen feet away on both sides of you. I should have furled that jib but no harm done.    Here is Shanghai:
 The other expected Harlem participants were Gene, not on "Chandi Nerissa", but on a friends boat out of Stamford, which I did not see, and Rear Commodore Peter, not on "Annandale" but on Ricks boat, now in Jersey City who hailed us immediately after the parade formally ended. Several other Harlem boats rafted up in a rendesvous in Oyster Bay these days so there were plenty of guest moorings available.

I felt guilty for not having purchased a replacement for our American flag and pole, which went missing during our winter travels to Florida. But Marty assuaged my  guilt somewhat by wearing an appropriate sweater.
It was too early to go home when the parade ended because the tide in the East River and Hellsgate were adverse. So we drifted slowly down the Hudson from midtown to the Battery under only the small jib and tide.

The wind was down from the 15 knots out of the north that had faced us during the parade: still from the north but perhaps six knots. And a light rain was falling. When we reached the Battery Lene wanted to go home as soon as possible to see the fireworks from our roof so we did what was silly: we went up stream against the tide using motor, full main and small jib. Unlike the eight plus knots we had enjoyed on the way down, we made speeds that got as high as 4.2 knots, briefly, and as low as 1.1 knots at times.  But we were back on the mooring by 7:30, an hour before sundown. If we had waited two hours before starting, I think we would have arrived only fifteen minutes later, having expended a lot less fuel in the process.
A good time was had by all.

HYC Cruise Day 4 Tuesday July 28 Mattituck to Noank 35 Miles

Views exiting Mattituck
     
Yesterday I described Mattituck Creek as "scenic," so I added a few views taken on our way out. Tide was "up" so no depth problems today

North Star left first, headed for Block Island where we will join them tomorrow. ILENE left next and took this picture of Blast as she passed us.

The wind was from behind, but rather light. It provided only a few tenths of a knot to our engine speed. The biggest help was the tide rushing out of the Sound as we passed alongside its end, pulling us along. ILENE got about three knots at one point, making 8.5.

The posts from this cruise are being sent back to the Club and posted on its own blog. The Fleet Captain, moi, made a stupid mistake but fortunately a harmless one. ILENE and Blast had made reservations at Spicers. However, in my mind, I was thinking of the Noank Boatyard, where the Club Cruise stopped in Noank in 2012. I remembered where the Noank Boatyard was and went there, despite PC Bruce advising last night that Spicers was a long walk to Abbotts lobster restaurant, where we had planned to have dinner. Bruce was right; he usually is. So arriving off the Noank Boatyard I found out that I did not actually know exactly where Spicers was. We had to go out again into Fishers Island Sound, go back east a bit and then North again to Spicers. The detour was only about 1.2 miles. In this picture the pencil points to Noank Boatyard, the pen to Spicers.
We asked to be berthed near Blast and they honored this request after a fashion as this photo from ILENE shows. A short swim away!
And yes it is a long walk to Abbots so we dined at The Sea Horse, located in Spicers, the six of us from ILENE and Blast. Food pretty good. It was another quiet night. A bit of wind would have cooled things off. It is always cooler on the water but snuggled into slips it was hot.
