Originally a Chinese merchant vessel named Yun Fong Seong No. 303, it was confiscated in 1992 by the U.S. Coast Guard when they discovered the ship was transporting almost 100 illegal Chinese immigrants to Hawaii. Unfortunately most of the immigrants made it off the ship and disappeared though some were captured and sent back to China and the crew was imprisoned. In 1993 the ship was sold to the Sea Shepherd Society who intended to use her to harass drift-net fishing operators. Ultimately they sold the ship to a Vietnamese fishing company in 1994 and this company re-named the 189ft vessel Sea Tiger.
Apparently there were issues the vessel leaking oil and fuel into Honolulu Harbor, which resulted in fines against the owners, which they never paid. The vessel was seized by the Coast Guard and impounded. The Voyager Submarine Company purchased the ship from the State of Hawaii and spent countless hours and large sums of money to prepare to sink it as one of their attractions.
Unfortunately, the company went out of business and never recovered their investment. The Sea Tiger is definitely advanced dive – the shallowest depth is 22m/70ft at the bridge level. Rear deck is 25m/80ft. as you move forward the deck levels drop to 32m/105ft and the ocean floor is 38m/123ft at the bow.
The ship has two large refrigerated cargo spaces in the main deck that are accessible by two large open hatches in the deck. Very large turtles are commonly seen in these spaces. It is possible to penetrate this wreck in several places, however the passageways are tight. It is recommended that only divers with deep diver certifications, advanced diver certifications or open water divers that have logged multiple deep dives, dive the Sea Tiger.
