• Trap: Abandonment does NOT discharge owner’s duty to locate, mark, remove (s.238).
• Compulsory wreck-removal insurance for ≥300 GT with direct action against insurer (art 12).
• Receiver of Wreck takes custody; owner may reclaim within ONE YEAR (s.245).
• Authority may act and recover cost from owner/insurer.
