Try this one on for size for hull cleaning.
100 grain primer cord ,weaved into a net ( like a cargo net ) strung under the ships hull, fore and aft and spaced 12 inchs off the hull plate with X type plastic spacers.
BANG - hull 100% clean.
Ships valves and hull plate must be in good condition for obvious reasons.
Old tramp steamer would go straight to the bottom, brite side now ya got a salvage job.
