  • Sailing Trans-Atlantic on the USCG Barque Eagle
    PassageRite of Sailing Trans-Atlantic On The USCG Barque Eagle odern life is complicated. I needed a car, a bus, a train and a taxi to get to my square-rigger. When no cabs could be had, a young police officer offered me a lift. Musing on my last conveyance in such a vehicle, I thought, My, how a touch of gray can change your circumstances. It was May 6, and I had come to New London, Connecticut, to join the Coast Guard training barque Eagle to sail her to Dublin, Ireland. A snotty, wet Measterly met me at the pier, speaking more of March than May. The spires of New Lon- don and the I-95 bridge jutted from the murk, and a portion of a nuclear submarine was discernible across the Thames River at General Dynamics Electric Boat. It was a day for sitting beside a wood stove, not for going to sea, but here I was, and somehow it seemed altogether fitting for going aboard a sailing ship. The next morning was organized chaos. Cadets lugged sea bags aboard. Human chains passed stores across the gangway and down into the deepest recesses of the ship. Station bills were posted and duties disseminated. I met my shipmates in passing and in passageways. Boatswain Aaron Stapleton instructed me in the use of a climbing harness and then escorted me — and the mayor of New London — up the foremast. By completing this evolution, I was qualified in the future to work aloft. Once stowed for sea, all hands mustered amidships.

  • Sailing Course Materials Overview
    SAILING COURSE MATERIALS OVERVIEW INTRODUCTION The NCSC has an unusual ownership arrangement -- almost unique in the USA. You sail a boat jointly owned by all members of the club. The club thus has an interest in how you sail. We don't want you to crack up our boats. The club is also concerned about your safety. We have a good reputation as competent, safe sailors. We don't want you to spoil that record. Before we started this training course we had many incidents. Some examples: Ran aground in New Jersey. Stuck in the mud. Another grounding; broke the tiller. Two boats collided under the bridge. One demasted. Boats often stalled in foul current, and had to be towed in. Since we started the course the number of incidents has been significantly reduced. SAILING COURSE ARRANGEMENT This is only an elementary course in sailing. There is much to learn. We give you enough so that you can sail safely near New Castle. Sailing instruction is also provided during the sailing season on Saturdays and Sundays without appointment and in the week by appointment. This instruction is done by skippers who have agreed to be available at these times to instruct any unkeyed member who desires instruction. CHECK-OUT PROCEDURE When you "check-out" we give you a key to the sail house, and you are then free to sail at any time. No reservation is needed. But you must know how to sail before you get that key. We start with a written examination, open book, that you take at home.

  • The Way of the Sea
    1 The Way of the Sea Cheney Duvall stared up at the great clouds of soaring sail, though her eyes watered from the sun and salt sting. The Brynn Annalea had found a tail of the northeast trade winds, strong and hot, to wend her fast down Baja and push her easily over the Tropic of Cancer. Her sharp prow knifed the water, the jib with the lucky shark’s fin mounted on it splashing in the wave crests. She was a beautiful thing, fast, sharp-hulled, streamlined, proud. And dangerous. Cheney shouted up at Shiloh, and he was shouting back down at her. Neither of them could possibly hear the other, but both of them kept on. “You idiot! Come down from there this instant! You are going to fall and die!” Cheney shrieked. He made an impatient gesture—Get below, you dumb girl!— which made Cheney’s heart almost stop, for he had let go with one arm to make jabbing “get below” motions to her. Twelve seamen were perched along the bucking, straining yard, feet kicked back against the footrope, bellies pressed against the yard, hands gathering up the heavy canvas. Cheney watched, horrified, as they struggled to roll the great main royal sail around the yard. Finally it was wound as neatly as thread on a spool, and the sailors, with strong and agile movements, passed lengths of rope around sail and yard and made it fast with hitches. One by one they started edging back along the yard, making for the weather shrouds to scamper down.

  • Colligo Marine® Lashing Tie Off Instructions
    Colligo Marine® Lashing Tie off instructions This image shows a nicely finished off lashing using our CSS71 Line Terminator and CSS61 Chainplate Distributor using 5 mm or 3/16” Dyneema line. You can see the critical hourglass shape that gets tighter as the shroud tension gets tighter. It is very secure but is also allows for easy unlashing. Without the hourglass shape you would need to place the knot at the bottom of the lashing which makes it very painful to lash and unlash. There is a series of individual half hitches that form the attractive spiral configuration of the lashing. This also creates redundant security ensuring that your lashing will not shake out. Tensioning Prior to lashing off please tension the shroud or stay to the desired tension. Tensioning can be achieved in several ways: 1. The best method is to take your boat sailing and adjust the leeward shroud, letting the wind blow the rig to leeward and do the work for you. Tack back and forth in low to moderate winds and keep adjusting the leeward shrouds. Always keep the mast straight and in column. In the end, you want your leeward shrouds to just come loose at your wind reef point, usually about 15-20 knots of wind speed. 2. You can also bring a halyard down and tie it off to your lashing line and use a winch for tensioning. This method will probably mean that you would need to help the lashing line thru all the holes in the line terminators and distributors while at the same time adding tension with the winch.

  • Tips of the Trade
    Sail Handling and Neil Pryde Custom Fittings he following are some of the special Neil Pryde fittings which every boat owner should be Tfamiliar with. Genoa Sausage Bags Neil Pryde Race and Premier Series sails are supplied with genoa sausage bags as standard. These bags make repacking easier and quicker. The bags have 2 full-length zips on top of the bag which run forward and aft from the clew to the tack. Before you attempt to put the sail in the Figure 11 bag make sure both sliders are at one end of the bag. Then pack the sail inside and slide one zip from one end to the other. Do not take it off the end of the bag. You can then throw the bag around quite freely and it will not come undone. When you wish to hoist, place the bag on the foredeck and run the zipper off at the front. The whole zip will then break open freely and the sail will be in position on the foredeck ready for use. (figure 11) Dousing Sock The dousing sock can be used with either a asymmetric spinnaker or a regular spinnaker. To hoist the sail, attach the halyard to the head ring on the sail and attach the tack downhaul line to the tack ring. It should then be passed through a turning block on the deck near the bow, and then to a cleat or winch somewhere near the cockpit. The tack will initially fly approximately five feet above the deck, so allow this amount of slack in the line.

  • Basic Rig Tuning (Mast Adjustment)
    Basic Rig Tuning (Mast Adjustment) ay the words “rig tuning” and most sailors assume you’re entering one of the most compli- Scated areas of performance control. This is not the case. For any sailor—except those at the very top levels—rig tuning should be a fairly simple exercise. For the cruising sailor the goal is complete rig stability even in the wildest conditions. In rig tuning, the racing sailor is seeking a mast that doesn’t bend sideways but bends fore and aft in a controlled manner. Later in the text we will go into one or two adjustments that the racing sailor might make for different conditions, but let’s start with the basics. Figure 10a First, check that the mast is not leaning to one side. To do this, tighten all the shrouds by hand until they are just firm. Then hoist a tape measure (or use the main halyard itself) to measure down from the mast head (top) to the chain plates (where shrouds attach to deck). Compare one side to the other. If equal, this will tell you the top is in the middle of the boat. If not, adjust the relevant shroud to pull the top over. The mast must, of course, be in the middle of the boat at the deck level. On most cruising boats the base position is permanently fixed, but double check just in case. Next, tighten both cap (upper) shrouds a few more turns, then move onto the lower shrouds. We will assume at this point that you have only one set of spreaders.
