  2. We will Cover • Boat equipment check • Boat Launch • Start & Stop the Engine • Pick up a buoy • Holding off from a fixed point for 30 seconds • Coming alongside a pier • Steer by compass • Steer by transits • Steering “blind” • Shot line deployment • Reverse figure of eight • High Speed Driving • “S” turns • “U” Turns • Man overboard • Turning on a warp • Anchor deployment • Coming alongside another boat • Recover boat • Towing disabled dive boat • Onshore presentations

  3. Practical Skills Boat Equipment Check Launch & Recovery Safe launch and recovery of boat Emphasis on local conditions Slip, wind, tide Launch equipment Safe storage of trailer • Pre launch checks • Oil level • Fuel level & Spare fuel • Sponsons (pump) • Equipment • Paddles • Dive flag • O2 & First Aid • Instruments • GPS, depth sounder, compass • Navigation lights, pumps

  4. Practical Skills Stop and Start Engines Loading a Boat Importance of correct loading and balance The effects of poor boat trim Equipment stored and tied down Boat brief Potential of injury Comfort • Safe method of starting and stopping engines • Start in gear protection • Gear selection • Fuel • Kill Cord • Cooling – tell tale

  5. Practical Skills Securing to a Buoy Holding off for 30 seconds Safe approach Using tide and wind Be alert to changing conditions and other mariners • Demonstrate securing to a Buoy • Covering safe approach and letting go • Effects of wind and wave • Knots • Starboard or port side approach

  6. Practical Skills Come Alongside Use of Compass Practical use of a boat compass Covering target and reciprocal bearings Passage plan Effects of boat movement on maintaining a bearing Wind and current • Safely leaving and coming alongside a berth • Effects of wind and wave • Safety to boat and crew • Lookouts • Bow and stern lines

  7. Practical Skills Steer by transits Steering “blind” To better understand environmental influences Current Wind Learner takes bearing on target and sets course Forward vision obscured Vigilance & safety • Finding suitable transits • Fixing and steering • Select suitable safe transits

  8. Practical Skills Shot line deployment Reverse figure of eight Starting position Pivot point change Control Current & wind Safety Flooding over transom Other marine users • Preparation • Flaking (barrel ?) • 25 kg weight (counterweight) • 50 litre buoy • 2 x 25 litre drums • Safety • Limbs • Tie off excess

  9. Practical Skills High Speed “S” Turns & “U” turns Competence Warning crew Appropriate speed adjustment Cavitation Stern wave Both directions • High speed boat operations • Covering effects of wind, tide, sea and loading • State of sea – calm vs. swell • Handling characteristics of boat • Informing crew • Safety

  10. Practical Skills Man Overboard Turn on a Warp Uses Safety Knot Technique Tie off Slow reverse • Spotting - lookouts • Returning to a given location • Approach • Communication with crew • Use of rescue equipment • Recovery of victim • Two 25 litre drums as mock victim

  11. Practical Skills Anchoring Coming alongside a boat Angle of approach Speed Stopping Passing a line Safety Hazards of catching between craft • Choice of anchor • Storage • Availability • Rapid deployment • Pre-launch preparation • Anchor, chain, rope, buoy • Confirming boat anchorage • Transits • GPS slippage

  12. Practical Skills Recover Boat Being Towed Principles of salvage Risk assessment Boat trim while towing Secure fixing points Minimize stress on both towing and towed craft • Local conditions • Wind, current, tide, slip • Recovery Method • Push • Drive • Winch safety • Draining • Raise Engine

  13. Onshore Presentations Rope Work Charts and Tides To cover the rudiments of chart passage planning and effects of tide Sources of information for passage planning • To cover a basic knowledge of Seaman’s knots • Practical demonstration • Description of rope types and their uses
