8. Boating Skills And Seamanship 8 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Types of Propulsion What are the four main propulsion types?

9. Boating Skills And Seamanship 9 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Outboard Engines Distinguish 2 & 4 stroke Advantages Easy to Service More deck space Less weight per HP Disadvantages Higher RPM (2 stroke) EPA issues (2 stroke) Transom cutout if used May be less efficient

10. Boating Skills And Seamanship 10 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Stern Drives Advantages Quieter Better fuel economy Durability, lower RPM Disadvantages more weight/HP loss of deck space lower unit many gears More gas = increased risk Large transom opening vs. inboard shaft.

11. Boating Skills And Seamanship 11 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Inboard Drive Advantages Simple gearbox & straight shaft All machinery but prop in boat Engine centered/balanced Good control for skiers Disadvantages Poor rudder control, esp at slow speed & reverse May disrupt deck space Thrust upward vs parallel to surface

12. Boating Skills And Seamanship 12 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Advantages No external prop Highly maneuverable Disadvantages Poor maneuverability at low RPM More slippage Often noisy Treated as toy Jet Drives

13. Boating Skills And Seamanship 13 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Hull Design How do these differ? Displacement Hull Planing Hull Semi-displacement Hull Reprinted with permission from Getting Started in Powerboating by Bob Armstrong

14. Boating Skills And Seamanship 14 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Displacement Hull What are four characteristics?

15. Boating Skills And Seamanship 15 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Displacement Hull Pushes through water. Low power to weight. Speed limited to hull speed, based on length at water line Relatively stable if chine squared, rolls if chine rounded or V shaped Uses keel or ballast for stability Rolls to outside in turn (centrifugal force) Handles seas well on the bow

16. Boating Skills And Seamanship 16 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Planing Hull What are five characteristics?

17. Boating Skills And Seamanship 17 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Planing Hull Requires high power to weight to get on plane Limited length due to power required Relatively flat bottom toward stern Rolls to inside in turn due to thrust Must slow to handle rough seas Stern often low, more vulnerable to waves.

18. Boating Skills And Seamanship 18 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Semidisplacement Hull What are four characteristics?

19. Boating Skills And Seamanship 19 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Semidisplacement Hull Reach partial plane but not full plane Draft less than displacement, more than planing

27. Boating Skills And Seamanship 27 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Boat Building Materials Steel Advantages Durability Strength Disadvantages Rust, metal fatigue & deterioration Weight Magnetic Electrolysis

28. Boating Skills And Seamanship 28 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Boat Building Materials Aluminum Advantages Weight Strength Good Heat Conductor Disadvantages Electrolysis & galvanic action Noisy, “oil can” effect Good Heat Conductor (condensation)

29. Boating Skills And Seamanship 29 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Boat Building Materials Wood Workability Relatively expensive Strong but heavy Considerable maintenance Declining availability

30. Boating Skills And Seamanship 30 Copyright 2007 - Coast Guard Auxiliary Association, Inc. Boat Building Materials Fiberglass Advantages Inexpensive Easily repaired Easily maintained; no seams or joints Easily protected against marine growth Disadvantages Resins that bind will burn Heavy Easy to cover up shoddy work
