PO-92 Ugor

Ugor (PO-92) was a logistic transport ship of the Yugoslav Navy, built in 1982 as one of a class of three ammuniton auxiliaries. Later sold into merchant service, the ship traded under Montenegrin ownership as Kairos I and Boka Star. She was involved in an arms-smuggling controversy in 2002, when seized by Croatian authorities.

Characteristics
Ugor was 58.20 m long, with a beam of 11.00 m and a mean draught of 2.75 m. Displacement was 600 t standard and 860 t full load. Two B&W-Alpha diesel engines with a total rating of 3480 bhp drove two shafts, giving a speed of 16 kn. The ship had a range of 1500 nmi at 16 kn. The ship was of Ro-Ro configuration, fitted with a bow visor and bow ramp to aid loading and unloading of vehicles, and with two slewing cranes on the upper deck. The main cargo deck could accommodate up to six tanks, while 150 fully armed troops could be carried in addition to the ship's crew of 43.

Naval service
Built in 1982, Ugor (PO-92) was the second ship, after Lubin (PO-91) and before Kit (PO-93), in a class of three small multi-role transport ships. They were built in the early 1980s for the Yugoslav Navy at the Brodosplit shipyard, Split to a national design by Brodoprojekt Rijeka, and known as the Lubin class by NATO. Their primary function was the replenishing of warships of the Yugoslav Navy with weapons, and as such were designated PO (Pomoćni oružar - Ammunition Auxiliary).

Following the breakup of Yugoslavia in 1991–1992, Ugor remained part of the Yugoslav Navy, but, together with Lubin was laid up, and in 1998, was reported as having been transferred to Montenegro for scrapping or commercial use.

Merchant service
In commercial service, she served under the Montenegrin ownership as Kairos I and Boka Star. The ship was involved in an arms-smuggling controversy in 2002, when it was seized by Croatian authorities, acting on a tip from American intelligence. As Boka Star she was owned by a Montenegrin, Marko Balić, and registered under the Tongan flag.

Seizure
On 22 October 2002, Boka Star was seized by Croatian authorities at the port of Rijeka, following a tip-off from American intelligence, on the suspicion that the ship was being used for arms smuggling. The ship's cargo, loaded at Bar, Montenegro, included 14 transport containers of chemical pellets, declared as activated carbon and water filters, but in fact 208337 kg of explosives. Balić was not brought to court, but was sentenced in absence to six years in prison. Following appeal to the Croatian Supreme Court, a retrial is pending.

Sale
The ship was sold by Balić in 2003 to the Esprite Shipping Corporation, based in the Marshall Islands, but the continuing legal proceedings resulted in the ship being kept under control of the court and being towed to Pula military port. Eventually, in 2011, Boka Star was sold at auction to the Croatian company Splitska Plovibda, but resold for demolition in Aliağa, Turkey as Star in February 2012.
