Chronicling a love affair with sailing

Barnacles!!

Argh!! The bane of my existence.

So, when I first bought the boat, I found that the previous owner had painted the prop with the same stuff used on the bottom. And it worked pretty good. The boat had hard paint on it and the hard paint was keeping the prop cleaned as well.

The first couple of years I had the boat, I used the same paint, and I did the same thing with the prop. But I am not a hard core racer, and I don’t play one on TV even. So the marina owner suggested that I might want to switch to ablative paint. That way, I could just slap it on and go, rather than going through all the prep process. So I did. He also suggested using PropSpeed to prevent barnacle growth on the prop. I did that as well.

PropSpeed is a pain in the patootie. It’s a two part application, and part two has to be applied immediately after applying part one. So it takes two people to do it.

So what happens when I pull the boat out in the fall? Well, the prop is full of barnacles. So much for PropSpeed. And at $250 (at the time – price is up another $50 now), that was a very expensive experiment. Mind you, I still have enough around for a second application. And there are still alot of people I’ve met who swear by it. So maybe I just didn’t get it on correctly.

But I moved onto the next suggestion: Barnacle Barrier. It’s much easier to apply. You just spray it on. But I pulled the boat and, again, the prop was filled with barnacles. Mind you, they were easier to scrape off from the prop. But the prop was still covered in Zinc, the main ingredient in the spray, and covered with barnacles as well.

Again, there are plenty of people who swear by the stuff. But with this, I can’t see how I could have applied it wrong.

Lately, members of the CAL mailing list have been touting the use of Lanocote for preventing barnacle growth. The literature says that it only works for 6 montsh. But I could be happy with that. It can also be applied underwater. So, if it isn’t working as long or well as expected, whoever is diving the boat can apply some more.

I’ve applied this to the prop and to the knotmeter paddlewheel. The latter may not be a good test, since it’s plastic, not metal. But it can be used as my canary in the mine: if the knotmeter isn’t working, it means the paddlewheel is covered in barnacles. So we’ll see how well it works.

It does apply pretty easily. The directions say to heat the metal to apply easily. I heated the substance, which melted under a blowdryer pretty well. I could then paint it onto the prop. Since I really couldn’t heat the paddlewheel easily, this allowed me to apply the Lanocote to the paddlewheel fairly easily as well.

I’ll try to update here to let everyone know how well it works.

Dunking

So, I was moving the boat over by myself last Friday so it could be hauled out for painting and other seasonal maintenance. There was a bit of a breeze, but nothing heavy. I had a line ready at the bow and beside me in the cockpit. There was enough of a breeze that the bow came in first, rather than my sidling up to the dock, so I went forward, grabbed the line, jumped to the dock. I tied on the forward line. By then, the aft portion of the boat had started to slip away, so I pulled on the lifelines, got hold of a stanchion forward, and started trying to turn the boat so I could grab the aft line and tie it off. The anchor got in the way, so I was pushing the bout out a bit to get the anchor positioned better. Well, me and the wind pushed it a bit more than I hoped and I found myself in a precarious position.

Don’t you love it when things start moving slow motion? Well, in those precious seconds, I was able to hold onto the lifelines as the boat slipped away from the dock. Unfortunately, I don’t have alot of upper body strength, so I let go and plunged into the water.

Luckily, the water was a nice temperature. Also luckily, there were no jellyfish and I was only 30 or 40 feet from the boat ramp. So I swam over and let myself out. I walked to the boat lift and grabbed one of their boat hooks (which I should have done in the first place). I pulled the boat over and tied up the rear. I went home and took a shower.

That afternoon, I started to hurt. I apparently hit a rib pretty hard, because there’s a big bruise on my back, but it mostly hurts in the front. Nope, I never did get checked out by the doctor. And there was still the work to do that I was hauling the boat out for in the first place.

So mornings I worked for a few hours, until it started to hurt. Then I’d take a break, go home, get some more good drugs, then go back and work a few more hours. Luckily, Erik and Wendy gave me a hand so I could avoid alot of the heavier stuff.

Now it’s all done. The boat is back in the water. I can recuperate.

What did I do right? I knew the marina well enough to know the closest place to get out of the water.

What did I do wrong? I should have waited until I knew there were people around, in case something went wrong. I should have backed the boat up and pulled up so the rear was closest to the dock, the way the wind was blowing. I should have taken a boat hook off with me to pull the boat in to tie it off.

Rambling

Wow! It’s been awhile since I’ve caught everyone up to date with what’s happening. But fear not – another season will soon be upon us.

Seasoned readers will notice that I’ve added a new category – cookin’ for the crew. The captains that taught me to sail also taught me that the best way to keep a happy crew was to feed them well. So I’ve tried to have something for the crew to eat after every race or during every cruise. Some recipes have worked well. Some, well, we won’t do those on the boat again. And I’ve had to find these recipes in my large collection of cookbooks, because every sailor-specific cookbook I’ve purchased so far (well, 3 right now) have assumed you have about as much available to work with in the galley as you do on land. Since my boat is a wee bit smaller than that, I’ve had to adapt – either by cooking it all at home, making it cold only, or making it something I could cook up or heat up in a hurry on my alcohol stove.

As I said, some recipes worked well. Some weren’t worth doing on the boat again. So I thought I’d try sharing a few of those ones that worked well. And who knows – if the collection gets big enough, maybe I can put them in a book.

Other things that have happened lately: my mom died on Christmas Eve. So Christmas Day, I went sailing. My boat is still my happy place and that’s where I wanted to be for this time. It turned out to be a beattiful day for doing it. As I tell people, the positive side of Global Climate Change is that my sailing season is extended.

But back to the sailing. Yes, I needed a jacket, and started with gloves and hat. But after a bit of time out there, I shed the gloves and hat and unzipped the jacket. The wind was great. The waves weren’t too high. And I had that portion of the river to myself. It was heavenly.

So starting the season. This year will be interesting. Budget is tight so the extra spring projects won’t get done. In fact painting the bottom will have to wait a bit, too. And I guess I’ll just slap on a coat of ablative, rather than having the bottom smoothed out by the folks at the marina as I planned. But she’ll sail. She just won’t be as fast as she might with a smooth bottom.

Here’s to 2013. May it be a better year!

The Long Road

Well, it’s that time of year again. The Cock Island Race is next Saturday. But family obligations left me with little vacation time. So, rather than taking the boat from Yorktown to Hampton on Thursday, then Hampton to Portsmouth on Friday, we took the boat up to Hampton on Sunday. This did offer the advantage that I had a weekend to check for optimal weather, rather than being locked into a single day.

Saturday and Sunday looked to be the same, weather wise: beautiful if you were on land or lounging at the beach, not exactly optimal for sailing. There was to be some breeze in the morning, but nothing in the afternoon. And the high temperature was expected to be 90. In other words, we’d have wind when it was cool in the morning and be roasting in the afternoon with no wind to cool us.

My crew for the day: Paul, Grant and Bette, were open on Sunday, so that’s the day we picked.

We were taking the boat to the Hampton Public Piers this time.  They offered a special with every 3rd night free and, if you paid for their annual ‘preferred guest’ pass, it was only $.75/foot/night as opposed to $1.50 – $1.75/foot/night at the other two places: Old Point Comfort and Salt Ponds. It would be about an hour farther than Salt Ponds, and we had made Salt Ponds before with no problem. Heck! We’d made it home from Hampton Public Pier last year without a hitch. So I decided to throw caution to the wind and not bring a generator for backup power this time.

The morning was beautiful. Not much sailing, since the breezes were light. But the sails were shading us from the sun and the temperature was pleasant. Early afternoon was about the same. We did get pushed by the wind a bit. But it was mostly motorsailing we were doing to keep the speeds up to at least 2.5 knots.

We did get some following winds to push us along. But the winds were fickle, changing direction enough that Grant and I got alot of practice putting up and down the whisker pole.

We had the autopilot on most of the time. I’d pick a marker at the end of whatever straight course we needed to follow. Paul would look it up on his phone’s Navionics app and give me the coordinates and I’d plug them into the Garmin 76CX GPS. This was much easier than finding the mark on that tiny map that the device gives, and it saved us using up Paul’s phone batteries by relying on it as the primary GPS device.

Towards mid-afternoon, Bette took over at the helm and the wind kicked up. I swear she brought the wind gods to our attention finally. We had had a bit of sailing before, but the winds had been so fickle that we have to be cautious that we were not losing ground by sailing back the way from which we had come. But after Bette took over, just past Salt Ponds, the winds were in our favor.  We were heeling 20 – 30 degrees and moving at quite  a clip – and in the right direction.

It was beautiful! I was finally able to turn off the engine. We were riding smooth. And the wind was keeping us from getting hot in the afternoon.

We spent about an hour doing this, making our way towards the Hampton Roads Bridge Tunnel, trying to figure out who the ships were that we were seeing and just enjoying the chance to finally sail.

I took over the helm as we approached the tunnel. I turned back on the engine and kept us at about 2 – 2.5 knots, mindful of the fact that the display showed us with about 2-1/2 hours of battery life left at that point.

When we got to Bluewater Marine, the first marina in the downtown Hampton area, I asked Paul to take over the helm. As soon as I did, you could hear the engine ramp down. Paul pushed the throttle up the entire way and it didn’t change things. We had already put the sails down, and we had a following breeze, so I tried to pull the jib out. It got stuck about halfway, something it had done the last couple of times we had brought it out. If I went to the roller, pulled it back to roll the sail back on, then let it go, it would work. I’ll need to look at it next week when I have a few experts around.

I had tried several times to hail the dockmaster and received no answer. I called and left a message on her cell. Someone on the radio said she’d gone home for the day, that I should just find a slip and talk to her in the morning.

The engine gave up about 15 minutes after Paul went behind the wheel. But we had the current with us and the jib. So we sailed into the Hampton Public Piers.

The first slip we found was right beside the one marked for the water taxi and dinghy tie-up. I wasn’t sure that we could use it, so we moved down the dock. We finally found #12 open and turned in. We were only going about 1 kt at that point, so we could pull ourselves along the side of our neighbor into the slip. I jumped off the bow onto the dock and stopped the boat. We did bump lightly into the pier but sustained no damage. We tied up, ensuring we had a good spring line to avoid bumping into the pier.

I was very grateful for the crew I had. They knew what they were doing and there was no word of complaint, even after the heat hit us bad once the engine gave out. They worked together efficiently as a team to get the boat safely into the docks. I’m very happy they were with me.

I was wondering, as we were drifting in, whether we could have used the house batteries, which are on a separate circuit and still had plenty of juice as a backup to get us into the slip. Since the batteries are quite different, although both are 12V, I don’t know if any damage would be caused. I’m going to put a note out to the electric boat mailing list and an email to Electric Yacht to get some insight. I’ll post what I find here.

Engine Efficiency

I checked the engine out the other day, when I had the luxury of a winter sail. It was making some awful racket. It was rattling quite a bit. So yesterday, I pulled the panels off to take a closer look. It seems the bolts holding the engine in place had worked their way loose. So I tightened them up again and took the boat out for a spin (hey, someone has to take her out! 🙂 ). Much better! Looks like I need to put some Locktite on the engine support bolts as I did with the coupler to the shaft.

While out there, I took some measurements on the efficiency of the engine. It’s something the electric boats mailing list recommends; it’s a good way to determine how far you can go on your setup. The wind was blowing, and the tide was coming in pretty strong, so I’ll need to do this again come summer when everything is calm. But this was a good ‘first run’:

Amps vs Knots

Amps vs Knots

Not exactly a straight line, and it probably never will be, since I’m not running in a bathtub where I can control all the environmental factors.  But interesting nonetheless. However, part of the ‘hiccoughs’ are because I would run downstream, then upstream to see how the values changed.

 

 

 

Amps vs RPMs

20120202 – Amps vs RPMs

 

 

This is actually more interesting, because it will help me determine how far I can go on a charge. I’m guessing the formula would be:

Battery amp-hours/amps * knots/hour = knots to travel

That’s amp-hours, as in the amount of energy stored in the battery, not amps minus hours.

Using this calculation, it appears I can go about 16.5 NM on a single charge, if I stay under 2.5 knots. If I up it to 5 knots, I can only go about 2.5 NM.

As I said, I’ll recalculate this in the summer when things are a bit calmer. But it’s interesting nonetheless!
