Tidelines: Prices rising

European and American boating industry suppliers of polyester resin and gelcoat are lifting their prices because of the rising cost of crude oil. A supply company spokesman says uncertainty over global oil supplies arising from the threat of war in Iraq and the strike in Venezuela meant further increases were likely worldwide for styrene, the key component in polyester resins.

Oleanda away

The 40m 300-tonne Oleanda, former flagship of the Blue Lagoon cruise operation in Tonga, is off to the Marshall Islands. After plying the Hauraki Gulf as a Louis Vuitton and America's Cup spectator platform, the ship has been sold to an island people's co-operative to begin a new life in the unspoilt waters of Rongelap Atoll. Virtually closed to all recreational activity since the American A-bomb tests at Bikini following World War II, the Rongelap area is home to a huge variety of marine life, including giant 2.3m clams. The present crew from Sunsail Charters will deliver the ship and train locals to take over. Details on Rongelap website.
