What you do with the machine: hull cleaning, spearfishing law, aquaculture, marina work, recovery, pools and photography.
Hull Cleaning on Surface Supply: A Field Guide
The job that pays for more WOLACH systems than anything else. Depths that matter, working a waterline, hose routing around a berthed boat, and why bottom time changes the economics.
Is Spearfishing on a Hookah System Legal?
In many places, no — and the rule is usually written about breathing apparatus rather than about tanks. What the regulations actually cover, why they exist, and how to check your own water.
Aquaculture: Net, Mooring and Cage Inspection on a Hose
Fish farms are the most demanding routine use of a surface-supply system. Long shifts, cold water, and more rope per square metre than anywhere else a diver works.
Marina and Pontoon Maintenance
Docks, pontoons, chains and piles. Shallow, repetitive, endlessly postponed work — which is exactly why it is the best kind of job for a hose.
Search and Recovery in Shallow Water
Most search and recovery work happens in water shallower than six metres, which is precisely where a hose is at its best. Patterns, tools and the discipline that makes a search repeatable.
Pool and Resort Maintenance
Zero depth, unlimited time, and an audience. Why pools are where a surface-supply system changes the job completely rather than marginally.
Underwater Photography on a Hose
No bubbles in the frame, no tank to bang on the reef, and as long as you like at one subject. Why photographers are the quietest fans of surface supply.
Propeller and Running Gear Checks
A five-minute job that requires the boat to be out of gear, the keys to be out of the ignition, and that fact demonstrated to you before you get in the water.
Invasive Species Removal: The Diving Job That Is Encouraged
Lionfish, urchins, mussels, algae. In a growing number of waters, removing certain species is not merely permitted to a hose diver — it is actively wanted.
Boat Layup and Seasonal Checks
Two moments a year when a hose pays for itself in a single day: the end-of-season strip-down and the pre-season check that finds problems before the first weekend.
