Georgetown Passage - Day 1, 12-28-08
[This email forwarded from sailmail status report.]
Georgetown Passage - Day 1, 12-28-08 We left you as we were arriving in Nassau, awaiting clearance into the Bahamas. We spent about a week there, relaxing and doing boat chores. Just like the saying goes, cruising is boat repair in exotic locations! One of our repairs was the annoying leak we'd had in the engine room, threatening our new inverter-charger. Past owners had piled some sort of goop - probably the ubiquitous 3M 101 caulk, a very good bedding material, as it remains flexible and can be removed later, if desired, without resorting to extreme measures such as required with their 5200 caulk, nearly universally used by cruisers for underwater bedding - on the pipe leading down from the cockpit scupper. That yielded to aggressive application of a utility knife, and we peeled it all off. It was immediately apparent that there was a ready explanation for the leaking we'd had. There was a nylon nut which was not fully seated against the fiberglass molded "bathtub" topsides, which caught the water behind a grate, leading it to a thru-hull in the bottom. I put my packing gland wrench - a specialty tool like a crescent wrench in concept, but with very long jaws, relatively thin for tight spaces, and which could open to nearly 4" - on the nut and commenced trying to back it out in order to get into the area under it for recaulking. However, Lydia, topsides, noticed that the fitting up there moved a bit, and as I got further down with the nut, it moved around in the "bathtub" as well as turned a bit. Hmmm…. I knew it was a thru-hull… Perhaps the nut could be lowered enough that we could get under not only the thru-hull as well as under the nut, to clean out the old caulking, to enhance the application of new. Since the top portion was turning slightly, I had Lydia hold the grate we lifted in such a position that it hit the corners of the "bathtub" so it wouldn't turn, and backed the nut down tight on the Ell it was above. That gave us a little working room, so we took folded sandpaper to the spaces, but it was extremely tight fitting, and didn't look promising. Thinking some more on it, I realized that if the top was turning, it had to be relatively free in the space it was put. I'd assumed it was just caulked into an Ell of the PVC piping used to channel the cockpit drains to the sea via the two 2" thru-hulls in the bilge. Perhaps if I could figure out a way to turn it enough, it would surrender its bond with the prior caulking and I could remove it, and start over. After much figurative headscratching, I found a piece of ¼" stainless steel I had left over from a project which fit into the slot in the thru-hull (think monster screwdriver in a straight-slot monster screw with a hole in the middle). However, it was pretty short, and getting something on it to make it turn would be challenging. Eventually I came up with a monster crescent wrench, which went over the ¼" stainless, and used another monster pipe wrench to turn it. Sure enough, it could be backed out, albeit very slowly and challengingly, as I had to hold the crescent wrench in position on the stainless with my fingers of one hand, and try to make the pipe wrench stay put on the crescent while I also tried to make the stainless stay in the slot. And, of course, eventually the nut below hit the bottom side again, so back into the Engine Room (my "cave" as one of our friends called it) for more backing off. Eventually, I had Lydia stay there to hold it while I turned the thru-hull out. It turned out that the Ell below was threaded, and the thru-hull had been threaded into it, with the application, perhaps, of 101, or maybe just plumbers "goop" which had somewhat solidified and made turning the thru-hull very difficult, initially. Our leak had been caused by, not inadequate caulk (though that certainly was the case), but, instead, a poorly centered hole through which the thru- hull passed. The lip of the thru-hull hit the sloped of the "bathtub" and was never flat on the bottom. So, grabbing the chisel and hammer, I took enough material off to allow the lip to lie flat. A thorough cleaning of both the ell's threads and the thru-hull threads, as well as the lip, assured a good mate for our rebedding. The Ell, meanwhile, of course, was a tapered pipe thread, while the thru-hull, as is the case on all of them, was straight. That would mean it would seat poorly, and the thread eventually would stop turning, as it jammed against the reducing diameter of the threads, but the threads would not be mated. However, with only running water as the pressure, we were confident that we could adequately seal it against water coming down the scupper. Rebedding was pretty straightforward. We liberally applied plumber's goop to the Ell's threads, which would provide an adequate seal there, and put a - let's just say - liberal amount of 101 on the nut and the lip of the thru-hull. So much so that, in the process of getting the nut on it, and into the Ell, 101 got on the threads a bit, but turning the nut up stripped most of that off. Just as in bedding our stanchion base, we threaded the fitting very tight (the same process as getting it out, in reverse, with lots of manipulation of the stainless steel piece, crescent wrench and pipe wrench) into the Ell, but made the nut and the lip only snug, and settled in to wait for it to set up a bit. A couple of days later, when the big overflow was no longer tacky, I had Lydia hold the top secure with the grate, and turned the nut below as far as it would go without stripping the edges. A satisfying amount squished out in both areas, and we have had not the first seep let alone any leakage. While it's a real PITA, we're now confident that if we should have to repeat the process on any of the other 3 (similarly glopped up below in the engine room), we will succeed at it. Phew! Many other 1-2-3s remain on our list, but none are mission-critical, so we wait for an enforced delay in our travels to address them. Back to the passage, we had our dinghy secured and we were ready to go to the fuel dock. During our walkings-around, chiefly to obtain our Bahamas cell phone, we'd checked with the couple of fuel suppliers and the diesel delivery had apparently happened, as it was pretty widely available. We'd originally thought we'd go to their dock at closing, and leave from there at first light. The dockmaster assured us that we'd be able to do that, but with the relatively heavy winds, and the limited time we'd have available, we elected to do that in the morning, instead. Earlier, I'd tried to find our weather forecaster to get a picture of what we'd be facing on our passage, but got nothing. I'd guessed that he must have gone on vacation, but, as we had a nice internet connection during our entire time at anchor, I'd been pulling regular wind gribs (a file which shows the direction of the winds on a map/chart) which showed heavy winds for the period we remained anchored, but that they'd moderate by the 28th. On the morning of the 28th, I tried again to find our forecaster, and, failing, put out an "any station" call to see if anyone else had heard him. Several responded saying they'd had no luck, either, but then one of the respondents called back saying that he'd just gotten an email from a friend. That showed that Chris was, indeed, away, and his replacement was using a different time schedule. He was on at the time, with others, and I succeeded in contacting him. His forecast confirmed our gribs, and we made ready to go the following morning. Early on the morning of the 29th, his forecasts again confirmed the conclusions I'd reached, and we prepared to get under way. Accordingly, we had our anchor up at 8:49, and stood off the fuel dock while, coincidentally, the boat which had informed us of the different weather forecast broadcast schedule, completed their fuel and watering. We fueled, learning that our constant motoring had yielded a consumption of about 1.3 gallons per hour of use during the time of our last fueling in Charleston, which included our trip to, and passage over, from Miami. We'd been very conservative with our water, and therefore took little enough that we weren't charged for that portion. Ironically, diesel fuel his cheaper here than in the states, about the same as at the pump shoreside, but probably a dollar or more less than in marinas, for which we were grateful. Apparently the tax structure is much less here, as they certainly have to pay more for their delivered fuel than the US based ones we'd fueled at on our way south. We were off the dock and under way by 9:45. The passage east out of Nassau is very tricky, with lots of rocks and coral and shoals, so we motored our way as we picked our path through them. By noon we were under sail in a stiff due-east breeze. Knowing that we'd be on a close reach or even beating, I started with a reef in the main, and then reefed the genoa to about 100% (the clew lined up with the mast) instead of its full 135%. Just for security, as we passed the coral heads and rocks about halfway there, we turned on the engine as we negotiated our way through them. They were easily seen and avoided. Because we were beating so hard, our speed was relatively slow, and we elected to motorsail the last couple of hours into Allen's Cay in order to have the anchor down in daylight. It was a tricky entrance in any event, so we'd need the engine then, anyway. Sure enough, we had the anchors (strong current there dictates two anchors) down in a protected anchorage between the three islands there. As this has been long enough, we'll tell you of our adventures ashore and underwater in a later posting. As always, those on our log lists will receive real-time reports, but those seeing these in the forums will have to wait until we have good internet connectivity. There's no internet service here, and we don't know when the next will be, but you can see our progress on our SPOT page, http://tinyurl.com/FlyingPigSpotTracking … Stay tuned :{)) L8R Skip and Crew Morgan 461 #2 SV Flying Pig KI4MPC See our galleries at www.justpickone.org/skip/gallery !

Which is an exceedingly wholesome thought, and one that may effect a permanent change in your deportment that will be greatly appreciated by your friends."- James S. Pitkin |
