It's a far cry from yesteryearr when practically all' boats were built from one material-wood. Now, there ls woodr fibergrlass, aluminun, steel, fero-cement, plus many combinations of these, For instance, yoo can see fiberglass hulls with wooden decks, lnteriors, and deck houses. The same is true for aL1 of the other material$. You don't need the desire to be a boat builder to learn more about boat building. The more you know about how boats are built and what materials are used to build them' the bet,ter you will be able to sel-ect a boat and then to maintain her year after year. This lesson will introduce you to sofite of the boat building materlals In use today and w111 explain the, steering systems you will find in nearly aL1 powerboats. FIBEF€LaSS=,BgryS. Iletrs begin l^tith fiberglass. Today, fj.berglass ffipo1izestheboatbui1ding1ndustry.Thiswasnot always so. The use of, fiberElass is a relativel,y new innovation and has on1y, within the last few decades, come to replace wood as the primary boat building material. The reason fiberglass has become so popuJ.ar is due to the fact that it is so easily maintained. Thousands of boat olrners have discovered to their delight that, taking care of a fibergJ-ass boat is far easler than maintaining its wooden counterpart, A J.ook at fitting-out yards in the spring is proof enough. Owners of wooden boats spend hour upon hour getting them ready for launching, Owners of fiberglass boats find that much Jess maintenance-time is required. But then again, fiberglass is not exactly a miracle material either. It requiree proper care and, contxary to what many people think, rreeds painting periodically. cH2 The word fiberglass doesn'treally define the material. It is more exactly plastic reinforced with fiberglass.The British use a more accuratedescription - CRP, which standsfor glassreinforced plastic. A fiberglasshull, then, is composedof shandsand layers of fiberglasssaturaled with iesin. This constuction can be comparedwith that of reinforcedconcrete. The fiberglassstrartds sompareto the steelrods and the resin comparesto ttre cement. Just as with any other kind of boat building material, there ate good fiberglassboats and bad fiberglass boats. There are ilulny ways to use fiberglass in building a boat and, predictably, there are firrr supportersof eachof these, Fiberglass itsel{ the reinforcing material,comes in four differerttforms-mat, cloth, wovon roving, and chopped strands(frgure 1-1).

It is used to slow down your boat or life raft when you are found in strong winds or heavy seas. More over it will stop your boat and turn it so as to face into or away from the waves. Further from the safety reasons, a sea anchor can be used as means to keep your boat as stationary as possible and not be pushed by the wind, thus very useful when you are fi shing, swimming, or in waters too deep to anchor.

Thank you for purchasing one of our Sea-Anchors. PARA-TECH® Engineering Company is in business to enhance offshore safety. Please do your part to promote, encourage and reward good safety habits on your ship! Set a good example by wearing your own life jacket on board. Practice man overboard drills. Review all safety matters with your crew. Do they know how to find and use the fire extinguishers? Will they be able to use the VHF to summon aid on their own? NEVER TAKE ANYTHING FOR GRANTED AT SEA Offshore safety is many things, but first and foremost it is that conservative attitude of mind that never takes anything for granted at sea! In particular, never take your SEA ANCHOR for granted. Remember also that drag devices are mere aids to seamanship and only as safe as those who use them. Remember also that different types of boats will react differently to different drag devices. The individual user should take care to determine prior to use that this drag device is suitable, adequate or safe for the use intended.

Sinking of US Cargo Vessel SS El Faro, Atlantic Ocean, Northeast of Acklins and Crooked Island, Bahamas, October 1, 2015. Marine Accident Report NTSB/MAR-17/01. Washington, DC. Abstract: On Thursday, October 1, 2015, the SS El Faro, a 40-year-old cargo ship owned by TOTE Maritime Puerto Rico and operated by TOTE Services, Inc., was on a regular route from Jacksonville, Florida, to San Juan, Puerto Rico, when it foundered and sank in the Atlantic Ocean about 40 nautical miles northeast of Acklins and Crooked Island, Bahamas. The ship had sailed directly into the path of Hurricane Joaquin, carrying a crew of 33, including 5 Polish contract repair workers. All those aboard perished in the sinking. As part of its accident investigation, the National Transportation Safety Board (NTSB) led a joint effort with the US Navy, Woods Hole Oceanographic Institution, and the National Science Foundation to locate the ship’s wreckage and retrieve its voyage data recorder (VDR). The VDR was pulled from 15,250 feet below the ocean surface in August 2016 during the third undersea mission and yielded more than 26 hours of parametric data and audio files.

  • Running Rigs, Dispatch and Storage by Jason Walker Setting up an Anchor Rig and How You Will Deal with Your Catch
    Running Rigs, Dispatch and Storage By Jason Walker Setting up an anchor rig and how you will deal with your catch. Anchoring and the Running Rig Anchoring on a kayak is very different to anchoring your normal runabout! On a boat you walk up to the front of the boat and throw out a big steel anchor, a long length of chain followed by however much rope you need to use for your depth. Anchoring a kayak is a little different, for a start you can't just walk to the front and throw the anchor over... So what you need to set up is something called an anchor running rig, this is in effect a rope of about 4 mm diameter that runs along the side of the kayak from the cockpit to the front, through a pulley, all the way to the rear of the kayak and back to the cockpit giving you in effect an endless loop. To attach your anchor to this running rig will depend on the fittings. The running rig will have either a stainless steel rig where the ends of the rope joins or it will be knotted in such a way that there is a tail of approximately one metre coming from the running rig with a clip or other attachment at the end. To anchor your kayak you then attach your chosen anchor to your style of running rig. It is now at this point that the running rig comes into it's own; from the comfort of the seat of your kayak you can choose to anchor from the front or the rear of the kayak just by moving your running rig between the pulleys.

  • BOAT CREW HANDBOOK – Seamanship Fundamentals
    BOAT CREW HANDBOOK – Seamanship Fundamentals Bernard C. Webber, USCG BCH 16114.4 December 2017 Chief Warrant Officer Bernard Webber “I reasoned I was a Coast Guard first class boatswain mate. My job was the sea and to save those in peril upon it.” On 24 January 2009, Chief Warrant Officer (CWO) Bernard Challen Webber crossed the bar. During his 20-year career, CWO Webber was the recipient of the Gold Lifesaving Medal and responsible for one of the greatest small boat rescues in Coast Guard history. Born in Milton, MA, on 9 May 1928, Webber began his career at sea in 1944 when he joined the Merchant Marine. After serving in the Pacific, he joined the Coast Guard in 1946. On 18 February, 1952, BM1 Webber was serving at the Chatham Lifeboat Station when a violent winter storm hit New England. Off the coast of Massachusetts, the SS Pendleton , a tanker originally built for the War Shipping Administration, was enroute from Baton Rouge, LA to Boston with a full load of kerosene and oil. At about 0550, in gale force winds, blinding snow and 60 foot seas, the vessel broke in two. In the bow, were the captain and seven crewmen. Thirty-three men remained in the stern section. There had been no time to issue an S.O.S. The stern section drifted south, about six miles off Cape Cod. The bow section was further offshore. As the men of Chatham Station were busy with the rescue of another tanker, radar picked up the two sections of Pendleton. Visually sighted shortly thereafter, it became apparent that aid could only be rendered by use of the 36-foot Motor Life Boat CG-36500.

  • Heavy Weather Essentials
    © 2006 Beth A. Leonard & Evans Starzinger HEAVY WEATHER ESSENTIALS Seven boats abandoned and six people dead in the Sydney to Hobart race. Four boats lost and four dead in this year’s passage out of the tropics to New Zealand. Two boats abandoned in the Caribbean 1500. It’s been a tough year for the offshore sailing fleets and perhaps time for each of us to revisit our heavy weather preparations. Unlike many other sports, once out in the ocean we are committed. We can’t just decide to quit and go home to a warm bath. We have to keep going no matter what gets thrown our way and must be prepared to be self-sufficient in every contingency. Being prepared for heavy weather is one of the ocean sailor’s primary tests. Waves Define Heavy Weather Waves define heavy weather, not wind. In flat water a well-found vessel with appropriate storm canvas can sail right up through hurricane strength winds. However, a cubic yard of salt water weighs about one ton. The crest of even a small breaking wave could easily smash 10 tons of water on your deck at a velocity of 20kts. Such force can knock most yachts down, shatter ports and shear off deck hardware. A yacht can safely bob up and down on 100-foot high waves so long as they are not breaking. Breaking waves add the critical unstable ingredient that can suddenly transform an exhilarating but essentially benign situation into life-threatening danger. Breaking waves don’t mean foamy white wave caps that slosh over the toe rail.
