About Sanko Harvest

A fertilizer tanker that sank off the coast of Esperance. The captain attempted a shortcut through the islands off the main channel and was apprehended for doing so. It spilled a lot of fertilizer into the water at the time and now sits protected by granite rocks in 40+ vis. The area is protected against fishing so the marine life is prolific. It is reported to be the second largest diveable wreck in the world to the Truk Lagoon's President Coolidge. It takes more than one dive to get the best of it.

Dive Site Hazards

Gradual Narcosis Onset — Narcosis may develop slowly, making self-assessment unreliable.
Task Fixation at Depth — Cognitive narrowing at depth can reduce awareness of time and ascent rate.
Increased Gas Density Breathing Load — Higher gas density at depth increases work of breathing.

Deceptive Entry Openings — Openings may become restrictive inside due to angle, collapse, or corrosion.

Surge-Induced Internal Silt Shift — Internal surge can move silt and debris without direct contact.

Partial Overhead Environment — Many wrecks limit direct ascent even without full penetration.

Fine Rust Particle Silt-Out — Disturbed rust particles can rapidly reduce visibility.
