Peter Deilmann Cruises is expanding the no-smoking restrictions on its European river fleet to include all areas inside the vessels beginning in 2008. The policy will become effective at the start of the river cruise season in March 2008. Deilmann, which operates a fleet of nine river vessels, first extended the smoke-free areas on its ships in 2005 to include all cabins and corridors along with its no-smoking policy in the restaurants. Now smoking will only be permitted on the open decks.
