  • Information About the LYS-System
    LYS – Nordic Handicapping System - 2003 Information about the LYS-system The purpose of the LYS system is to give yachts of different classes the option to race against each other. The LYS number indicates what the “best” yacht of each respective kind is able to perform to. It is based on race statistics, which is a comparison between different types of yachts and experience. The table is split in four groups, keelboats, sport boats, dinghies and multihull yachts. The corrected times are normally calculated by simply multiplying the elapsed times by their respective LYS-figures. The LYS-values are applied similarly in Sweden, Norway, Finland and Denmark.

  • Mt Marine Composites Article
    The Promise of Marine Composites Realized Fifty Years of Marine Composites Composites are defined as the combination of two or more materials that produce structural properties superior to the materials on their own. This can be anything from mud and straw huts to concrete reinforced with rebar but today we usually understand composites to mean fiber reinforcements combined with polymer resin matrix systems. Fifty years ago, marine composites were almost exclusively fiberglass, a combination of E-glass reinforcement and polyester resin. Today, high performance reinforcements, such as carbon fiber and Kevlar®, are combined with advanced resin systems to produce very strong, lightweight structures that were not possible fifty years ago. Fortunately, design methodologies and manufacturing processes have also advanced so everything from racing kayaks to destroyer deckhouses is now built with marine composites. Recreational Boats Fiberglass construction of recreational sail and powerboats really took off in the 1960s as builders realized they could manufacture multiple copies of the same design from a single mold. Complex shapes were easy to reproduce and the “non-corroding” fiberglass laminates were marketed as virtually maintenance free. Widespread mass production made boating affordable to many Americans and the industry closely tracked the country’s prosperity. Unfortunately, designs and manufacturing processes were developed by trial and error, which led to some boats that failed over time and some that would be considered “overbuilt” by today’s standards. Commercial Vessels Fiberglass construction was particularly attractive for the construction of commercial fishing boats, especially in the Pacific Northwest. However, the boom-bust cycle of local fisheries saw the boats lasting longer than the industry they supported.

THE BY WILLIAM B. BRADBURY. Published by BIGLOW & MAIN, No. 425 Broome Street, (Scrcwiou TO ViS. B. BIUDIU'RY.; IYISOX, BLAKEMAIT, TAYLOR & CO., 138 k 140 GRAND STREET AND FOB SALE BY BOOKSELLERS GENERALLY. PREFACE. It is now generally acknowledged that no one agency has added so much to the interest folt by children in our Sunday Schools as singing; and the Golden aeries, commencing with the GOLDEN GUAM, was among the first to claim the popular attention in this interesting and elevating exercise. The new impetus which this popular work gave to Sunday School singing, made a demand for now books, and in due time the CHAIK was followed by the GOLDEN SHOWER, and finally by the GOLDEN CENSER. Millions of them were sold in a short time, and when the electrotype plates were worn out, and it became necessary to make new ones, the books were revised and improved. In this volume the three volumes are presented under a new name; and we do not hesitate to pronounce "The BRADBURY TRIO " the largest, most complete, and in every way most desirable Sunday School Hymn . and Tune Book in the world. It contains many Hymns and Tunes that will never wear out, and it will long hold its place in the front rank of Sunday School Songs.
