MV Captain Keith Tibbetts

The Tibbetts is the Caribbean's only readily divable Soviet-built warship — a Koni-class frigate delivered to Cuba's navy, bought by the Cayman government, and scuttled off Cayman Brac in 1996 with her gun turrets still aimed at nothing. Storms have since snapped her spine: the stern sits squarely on the sand while the bow leans away at a drunken angle, and the break lays her innards open like a cutaway drawing. Divers frame the forward guns against blue, wander the split, and check the hull's sponge growth for seahorses the Brac guides track. She wears a local diver's name, honoring Brac heritage.

その瞬間のために: Cold War frigate with gun turrets, the storm-torn break amidships, easy recreational depths.

地形: A Soviet-built Koni-class frigate scuttled in 1996 on sand, now broken amidships with the bow section listing.

エントリー: Lies off Cayman Brac's northwest shore; dived from Brac operators and on sister-island trips from Little Cayman.

危険生物・リスク: Unstable broken structure and sharp edges; interior spaces are deteriorating — stay out of the break.

保全: A managed artificial reef; the collapsing midsection is off-limits for penetration.
