1 Small Boat Diving

2 Objectives Identify the following areas of the boat:
Bow, stern, starboard side, port side List the minimum safety gear required by the USCG. Describe Procedures for launching and recovering a small boat from a beach. Outline concerns and procedures for anchoring. Discuss techniques for entries and exits from a small boat. Describe techniques for diving in current.

3 Main Topic Areas Positives and negatives of small boat diving
Terminology Safety Gear Loading Launching Anchoring Diving Beach Landings Emergency Procedures

4 The Positives of Small Boat Diving
Small boats are excellent dive platforms Allow us to reach sites otherwise not easily accessible. Relatively economical. Easily transported Successful small boat operation and diving requires: Planning Boating skills Teamwork

5 The Negatives of Small Boat Diving
Crowded space Possible sea sickness Time consuming Boat Issues

6 Terminology Bow Stern Port side Starboard Front of the boat
Back of the boat Port side Left side of the boat as you face forward Starboard Right side of the boat as you face forward

7 Safety Gear Determined by the size of the boat USCG requirements
USCG approved PFD for each passenger “Throwable” PFD Visual distress signals Fire Extinguisher Sound making device Registration and hull numbers

8 Safety Gear Nice to have First aid kit Tools
Radio or other communication equipment

9 Loading Capacity Plate Keep all cargo organized Keep the boat balanced
Maximum number of passengers Maximum total weight Maximum size motor Keep all cargo organized Individual soft/mesh bags for divers Keep the boat balanced

10 Beach Launching Position the boat with the bow toward the water
Locate the boat as close to the water as possible Time the sets to enter on the calm period Follow the last wave and let the water do the work Get through the surf zone as quickly as possible

11 Beach Launching Hold the bow toward the waves
It may be necessary to paddle the boat away from the beach Once in deep enough water Lower the motor Start the motor

12 Anchoring Ground tackle Anchor Type Scope Anchor Line
Typically nylon for strength and flexibility Chain at the bottom Protects against chafing Acts as a shock absorber Anchor Type Select the correct anchor for the bottom type Rock Anchor Lightweight “Danforth” style Scope Ration of Length of Anchor line deployed to depth of water 3:1 minimum 5:1 preferred

13 Anchoring Anchoring Drill Allow plenty of room for swing
Make a test run. Always lower the anchor. Never throw it. Make sure the anchor is attached, but can be slipped quickly. Leave the engine running until you are sure the anchor will hold. Pull back on the anchor to set it.

14 Anchoring Anchor bearings Checking the anchor
Ranges to landmarks on the beach to establish position Compass bearing to landmarks on the beach to establish position Checking the anchor Upon descent check the anchor to make sure it is set. Prior to ascent, check the anchor to make sure it is clear to hoist.

15 Anchoring Hoisting anchor Motor slowly up to the anchor.
Hoist being careful of your back.

16 Diving Procedures Entry into the water
Make sure the entry area is clear Technique Backwards roll Sit and slide Timing Keep the boat balanced Simultaneous entries from opposite sides Alternate entries from opposite sides Equipment management Avoid entanglement Gear up completely in the boat Don your gear in the water

17 Diving Procedures Exit from the water into the boat Technique
Ladder Over the side It may be necessary to enter over the stern of the boat May be lower or more stable Equipment Management Do not remove any equipment until you are in contact with the boat. Attach equipment to gear lines or have another diver hold onto the gear Properly stow the gear as soon as you are in the boat.

18 Diving Procedures Current Begin dive into any current
Deploy a current line for diver retrieval Allow for the effects of current on air consumption Use the anchor line for safety stops

19 Diving Procedures Liveboating Is vessel maneuverable enough?
Is prop a hazard. Most boats drift bow down. Entering the water Divers should exit the boat on the windward side Pick up Windward vs. Leeward side

20 Beach Landings Stop in deep water as close to the surf zone as possible. Raise the motor Time the exit to follow the last wave of the set Divers are in the water ready to drag the boat up the beach Boat orientation Bow toward the beach Stern toward the beach

21 Emergency Procedures Recall Procedures Recall Signal Diver Response
Racing motor Banging metal together underwater Diver Response Make a safe ascent Look to boat for signals

22 Emergency Procedures Radio protocols
VHF Channel 16 is the emergency channel Levels of emergency MAYDAY Vessel is in imminent danger PAN (pronounced PAHN) Potentially life threatening situation Overdue or missing divers Man overboard DCS or AGE SECURITE (pronounced SAY-CUR-EE-TAY) Hazards Safety Navigation Weather

23 Emergency Procedures Info to transmit Location Boat identification
Type of emergency

24 Emergency Procedures Rescues Strip gear prior to entering the boat
Enter at the most stable part of the boat May be over the stern of the boat Inflatable Boats May have to partially deflate a pontoon

25 Main Topic Areas Positives and negatives of small boat diving

26 Objectives Identify the following areas of the boat:
Bow, stern, starboard side, port side List the minimum safety gear required by the USCG. Describe Procedures for launching and recovering a small boat from a beach. Outline concerns and procedures for anchoring. Discuss techniques for entries and exits from a small boat. Describe techniques for diving in current.

27 Summary Proper utilization of small boats will significantly extend the range of your diving operations. Successful small boat diving operations calls for proper planning, boating and diving skills and teamwork.
