Royal Institute of Naval Architects coat of arms

Choosing a surveyor who is a member of a Royal Institution ensures he is well qualified to a clearly defined and internationally accepted standard.

The Royal Institution of Naval Architects (RINA) requires its members to have a minimum qualification of a degree or endorsed HNC in the subject of naval architecture, and have at least ten years proven experience in a responsible position within a shipyard or yacht yard.

John Merrett I.Eng., M.R.I.N.A.

My own training began in the 1960s building and refitting yachts to the Lloyds standards and fishing vessels to White Fish Authority rules. During the 1970s I qualified as a Naval Architect and continued building, re-fitting and repairing yachts, fishing vessels, lifeboats and MOD vessels until September 1994. Since that date I have traded as a self-employed independent Marine Surveyor carrying the necessary indemnity insurance cover. The main part of this present day work is for pre-purchase or insurance surveys for sailing and motor yachts.

Survey prices

Metal vessels are surveyed using Cygnus Multiple-echo thickness testing equipment.

Diesel engines are compression tested using regularly calibrated Sykes-Pickavant compression testing gear.

Standard charges for local purchase surveys are based on the simple formula of:
Length (on deck in feet) x Breadth x 1.3 in GBP

Survey Fees for larger vessels or for insurance purposes are normally less.

Engines of motor vessels and larger yachts are normally compression tested and there is an additional charge for the spanner work involved in dismantling machinery here.
