Pre-purchase + 6 oil analysis samples and sea trials were carried out in the Solent on this 65ft fisheries protection vessel (FPV) that is now used to carry out surveys around the coasts of the UK. The build was solid and the condition of this working vessel is a credit to the owners. How do you save fuel when out surveying, simple instal a third small engine and not run the two main Detroit engines. The sea trials were great. Thank you to all involved.
