■Important points when boarding / disembarking

Before boarding or disembarking, make sure that you have not left your any equipment.

Get help from boat staff when boarding and disembarking.
If you step over the boat carelessly, there is a risk of falling into the water.

Get on and off the boat with no luggage and move your luggage in cooperation with other divers.

When you get on board, organize your equipment and keep it close to you before leaving port .

Do not put your hands on the hull of the boat.
Serious injury will result if your hand is caught between the boat and the quay.

If you get caught on a wound rope or wire (a metal rope), you will be seriously injured.
Keep away from wound ropes and wires.

Anchor is not only heavy, but also has a tapered tip, so safety preventions are required.
Keep away from the anchor.

You will be seriously injured if you get caught in a windlass.
Keep away from the windlass.

Small boats are unstable because they shake due to waves, wind and tides.
Sit on the deck while boat running. Do not sit on the hull of the boat or stand on the deck.
