Run a line from the Samson posts, through a hawse hole, and under the keel to the boomkin cleat on the opposite stern quarter. Draw the line up tight for the diver to use as a hand hold.
Add an additional dive weight, aiming for neutral buoyancy at a depth of 1.5 metres, after equalising naso-pharyngeal pressure.
Wear industrial Kevlar-reinforced work gloves.
Swim against the current, if any, and then clean the hull while drifting back with the current.
To clean the hull efficiently, use a 3M 6473 Doodlebug handblock pad holder with a white pad. A smaller handblock pad, such as the size sold for barbecue grills, is useful around the propeller and rudder.
