Since its introduction to the VT Halmatic range in 1993 a considerable number of Nelson 42 Mk11s have been built as patrol boats. Operators of these boats include HM Customs and the Royal Gibraltar Police. VT Halmatic has also moulded many motor yacht versions and two pilot boats, for Venice and La Rochelle, which were fitted-out by yards in Italy and France. Due to the continued success of the venerable Nelson 40 VT Halmatic has designed a pilot boat based on the Nelson 42 Mk 11 hull. The customer for the first of class vessel are the Tenerife Pilots, who having admired a Nelson 42 patrol boat in service with Las Palmas Port Authority, chose the VT Halmatic Nelson 42 hull form over other options available from the VT Halmatic range.
