Good Seamanship • SIZE OF BOAT • COST OF BOAT The Basic Principles of GOOD SEAMANSHIP apply regardless of OR SAFE BOATING ISNO ACCIDENT
Importance of Boating Safety How to talk about boats and motors Variety of boats and motors Boat hull types and boat use Essentials of Boat Construction Match boats to needs Boat defects, contracts, & insurance Lesson Objectives
Much derived from ancient sailing days Norwegian rudder was a “STJORN” (pronounced starn) STJORN BOARD was on right side of vessel – facing to front Right of vessel became STARBOARD Boaters Language
Boaters Language • Left Side of Vessel was next to Dock (Port side) again facing front • The Loading Board was on the LEFT side • LOAD BOARD became LARBOARD • LARBOARD / STARBOARD sounded too much alike • LARBOARD changed to PORT • PORT - STARBOARD
Boat Power Outboards Stern Drives Inboard/outboards I/O
Outboards • Disadvantages • Higher RPM • Less efficient Operation • EPA • May require a transom cutout • Advantages • Easy to Service • Take up less room • Less weight per • HP • Trim the drive
Stern Drives Advantages Quieter Better Fuel Economy Lower RPM Trim the drive Disadvantages More weight per HP Loss of Deck Space Lower unit Gearing Problems Danger of Fire & Explosion
Advantages Simple gearbox & straight shaft All machinery but prop in boat Engine centered and balanced Good control for skiers Disadvantages Poor rudder control, esp. at slow speed & reverse May disrupt deck space Thrust upward vs parallel to surface Inboard Drives
Safety – no propeller Operate in shallows High speed No prop walk More slippage Need power to steer May be noise Jet Drive
Hull Types Displacement Planing
Utility Boats • Prams • Dinghies • Inflatables • Skiffs • Utility Outboards
Runabouts Bowrider Cuddy Cabin
Cruisers Deckboats Houseboat
Boat Construction • Steel • Advantages • Durability • Strength • Disadvantages • Rust, metal fatigue & deterioration • Weight • Magnetic • Electrolysis
Boat Construction Aluminum Light weight Difficult to protect from Marine Growth Susceptible to Electrolysis Good Heat Conductor Noisy
Wood Workability Relatively expensive Strong but heavy Considerable maintenance Declining availability
Fiberglass Fiberglass layers / strands saturated with resin Advantages No seams or joints Strong Molded into any desired shape Low maintenance Easily protected against Marine growth Disadvantages Heavy – Heavier than water Easy to cover up shoddy work Resins that bind will burn
Construction Process Hand-Lay-upChopped-Strand
Construction Process Matched Die Process Male and female molds used Clamped together with Laminate between Sandwich Process Core material covered with layers of fiberglass Usually Balsa Wood – sometimes Foamed Plastics or Plywood Strong and Buoyant
