The following amendments and additions to the existing (1960) Regulations for Preventing Collisions at Sea are offered for comment by Institute members and others interested in this problem.

The only comment which we wish to make about them at this time is that we do not claim that any of the ideas on which these suggested new rules are based are our original ideas—they have only been sorted out, into what we hope will prove to be a satisfactory arrangement, from many ideas which have come to light and have been aired during exercises and discussions that have taken place during radar simulator courses conducted at the Welsh College of Advanced Technology over the last five years and during discussions with many members of the staffs of other nautical colleges and with nautical surveyors of the Board of Trade. The ideas put forward by many notable persons in the various nautical publications have also been studied and have greatly influenced us.
