As I said, we are keeping the entire situation under constant review, but at the moment we do not consider that the adaptation and use of laid-up trawlers would be as cost-effective as new ships, in terms of remaining hull life and continuing support. On the second point, two Bird class patrol ships—"Kingfisher" and "Cygnet"—are currently in service with the Fishery Protection Squadron. They are designed for work in coastal waters only and are weather-limited. A contract for four was placed on 10th November 1972 with Richard Dunstan's (Hessle) Ltd., of North Humberside, but delays in delivery dates have been experienced due to labour and technical difficulties. No new orders have been placed. The two remaining vessels under construction will be allocated to the RNR.
