The trip from Virgin Gorda, BVIs to Portsmouth, New Hampshire wasn't without a bit of adventure. We were, after all, doing this at the begining of huricane season, first of August, 2008. There were three of us: Capt. Ben (me), Bill T., and Sally K. The crew had sailed on Mother of Perl before; Sally for nearly a month, island hopping from Tortola, BVI down to St. Lucia with extended stay in Dominica. We all knew what is was like to live and sail this rugged boat. The plan was to leave the mooring in Trellis Bay, Beef Island/Tortola the morning after everyone was in the BVIs, motor upwind to Spanish Town, Virgin Gorda (about one hour), fuel and provision, then the next day depart due north to Bermuda, provided that there were no storms threatening. We expected the passage to take about a week, which it did. We ran with 4-hour watches. The captain was on call 24-hours, so he had the morning and evening watches. We started out with a good strong wind on the starboard quarter, but it settled down by the end of the first day. We motorsailed at night and sometimes during the day when there wasn't enough wind to get us going four knots. The wind and seas picked up the day before we arrived in Bermuda, but the timing for a direct approach would have brought us in near midnight, so we tacked far to the northeast and back to the northwest to make our arrival at daybreak. Radio Bermuda, the coast guard VHF radio station, was extremely helpful getting us in through the Town Cut and to the Customs and Immigration dock. The formalities took only a few minutes and we moved to the town dock where we spent that night. During the next day, we shopped and did laundery. The next day, we fueled up and filled our water tanks and were underway before the cruise ships had crowded the harbor. As with the exit from the BVIs, we left Bermuda with a good stiff breeze of 20 knots, but it died off to less than ten knots by the end of the first day. We had barely gotten 150 miles north of Bermuda by nightfall of the second. The forecast had our hopes up, however: "15 to 20 knots from the southwest." Sure enough, the wind very gradually rose to 15 knots as the day came to an end. By 2300 (11PM), we were moving along well with jib, main, and mizzen. Because it was night time sailing, we took the precaution of having two reefs in th main. My watch ended at 2300, so I went to bed. (We had shifted the watches when we left Bermuda.) I woke at 0300 and immediately noticed the boat motion felt like we were surfing. In fact, we were. The boat speed was over ten knots. (The maximum displacement speed is nine knots.) Within minutes, there was a load crack followed by deafening flapping of sail. We started the engine as an emergency response. Bill T., who was on watch, and I made our way up on deck and found that the clew of jib had ripped away. We dropped the jib (no roller furling made this easy) and gatthered the sail onto deck. The wind was more than thirty knots and gusting to forty. Without the jib, the sail plan was severely out of balance with power shifted aft. But the wind was still over the quarter so the consequence was not significant until the wind shifted. Nonetheless, we atempted to drop the mizzen, a foolish plan considering the strength of the wind. It jammed in the shrouds. We could neither drop it nor bring it back up, and had to leave it billowing in the shrouds. Since the jib had blown out, we were motorsailing and doing 1-hour watches, the three of us. Around 0600, we heard another crack. This time it was the rivits holding the pad-eye for the mainsails second reef. The reef was blown and this sail was bilowing in its shrouds. The wind was in the forties gusting into the fifties, too dangerous on deck to do any work to prevent any more damage to the sails. It was more important to stay safe below, out of the wind and now heavy seas. Within a few hours, the wind had clocked around to northwest, our rhumb line course. The wind had dropped back into the thirties, still enough to build seas, now there were 15 foot seas from stern, 8 foot seas on the bow, and an occasional wave directly on the beam. The later was the most dangerous. The first danger is roll, but Mother of Perl is so beamy and has so much ballast in her full keel, that she rolled a maximum of 45 degrees, and usually no more than twenty degrees. The second danger comes from when she isn't rolled when the beam sea hits. The majority of the hull is vertical and flat. When a sea hits this surface, it is like a seawall, the water shoots straight up and comes crashing down on deck, covering the deck with half a foot of green water for the few moments before it drains away. The dorads (vents) are designed for only two inches of water. The result is water in through the vent pipes of the dorads, not much, but enough to make a mess. One hatch, as well, had trouble holding back that much water. When got around to cleaning up after the storm, it didn't amount to more than ten gallons, total. By noon, the winds had subsided to twenty-five knots, and the seas had become more regular. But before that happened, the vessel motion was so choatic the the GPS couldn't give us a course or fix, nor could the autopilot steer. Our velocity was down to one knot, at best. There were times when we actually were going backwards in relation to the bottom, but forwards through the seas. We were steering by hand and by magnetic compass. Thank goodness for dampening the compass. In reality, the seas governed our course more than the compass. Once the autopilot and GPS had reestablished themselves, Sally K. and I went on deck to try to tidey things up and assest the damage while Bill T. stood watch and kept us from being washed away by seas. Using tethers on our harnesses to keep us secured, we relashed the jib, which had come loose, secured the main to the boom, and did the same with the mizzen, which had torn across near the top and was trailing along with various sheets in the seas by the boat. We also discovered that the dinghy had been destoyed and was hanging by a single fall from the davits. The outboard had smashed against the stern of the boat in the process. They were of little salvage value and dangerous to recover, so I cut the dinghy free to drift off to the Azores or Africa. There had been considerable damage to sails, and the loss of the dinghy left us without any emergency liferaft as well as just being financially a pain, but we and Mother of Perl were in fine shape, save a few bruises. She proved herself as an incredibly strong and safe boat. Now the question was how we were going to get home. We were 200 miles or more from Bermuda and 400 miles from the nearest port in the USA. All we had was our little 80hp diesel engine. By 1600, the wind was down to less than twenty and seas were flattening out, relatively speaking, so we returned to our regular four hour watches. I sounded the fuel tanks and found we had about 500 liters (150 gallons) left. At 2000 RPM, the engine uses roughly 5 liters and pushes the boat 5 nautical miles in ideal wind and seas. That works out to one liter per nautical mile. If we could avoid any more adverse wind and seas, we should have plenty of fuel to motor to our destination of Portsmouth, NH. If not, Nantucket and Cape Cod were closer. We would at least be within radio range of fishing boats when we ran out. To be sure that we got the most distance from the fuel that we had, we kept the engine at 1800 RPM.
For the next two days, the wind was less than ten knots, on the nose, but light, and the ocean flattened out. We relaxed, ate and slept well again, and remained patient about our arrival, despite a certain urgency for Bill T. to get back in time for an important real estate meeting on his new house. I sounded the tanks each day. We were getting at least a nautical mile per liter. On the afternoon of the third day, we had reached George's Bank, a prime commercial fishing ground. We wouldn't be able to pull in to Nantucket or a Cape Cod port during the day, but we had plenty of fuel. We were able to call the US Coast Guard on the radio and pass on the information that we would be a day late in arrival. They would call our families. The next day brought us close enough to Cape Ann that our cell phones worked and we called and confirmed our arrival for that afternoon. We didn't mention what condition the sails were in. We arrived at the New Castle pier at 1600 and were greeted by our wives. Sally would have to wait another day for her sweetheart to arrive from Oregon, a big surprise visit. Mother of Perl now sits in Portsmouth. Her sails are at the sailmaker. The teak bowsprit decking which had been destroyed by the waves is replaced with fiberglass reinforced plastic grating. She has her own mooring thanks to the purchase of share by a local mariner with a seldom used mooring. All is well, but none of us are quite ready to go out in the deep blue sea. |
