Note that the Length Overall (LOA) may be over 24m. The statutory instrument for guidance is; The Merchant Shipping (Tonnage) Regulations 1997 Statutory Instrument No. 1510 See Appendix 1 for a copy of the SI. Definitions used in this manual are taken from the SI. In addition to British Registration, the IIMS CA is also approved by a number of other Red Ensign Flag States as follows; Jersey – Vessels less than 24m length Guernsey – Vessels less than 24m length Isle of Man – Vessels less than 24m LOA BVI – Vessels less than 24m load line length Cayman Islands – Vessels less than 24m load line length Most of these Flag States have different methods of measurement and/or information’s that are to be included on their forms compared with the British requirements. You should therefore make yourself familiar with the requirements of each Flag State prior to undertaking that Flag States survey. All current Tonnage Survey Forms for each Flag State are available to download at; www.iims.org.uk/vessel-coding/certifying-authority-examiner-resources/ Page 3 of 19 IIMS Tonnage Survey Manual - Jan 2017 V3 © IIMS CERTIFYING AUTHORITY 2017 Who can undertake Tonnage Surveys through the IIMS? You must be an IIMS Associate or Full Member. Applications for approval are to be made to the Certifying Authority Applicants need not be a Certifying Authority Surveyor for MCA Coding but may be approved as a CA Tonnage Surveyor only. To apply please contact the IIMS CA Administrator for an application form: [email protected] Page 4 of 19 IIMS Tonnage Survey Manual - Jan 2017 V3 © IIMS CERTIFYING AUTHORITY 2017 Tonnage Survey process Client contacts IIMS CA or Surveyor and requests a Tonnage Survey. Surveyor carries out Tonnage Survey using either; ‘UK Certificate of Tonnage Survey’ forms or other Flag State forms as found under the CA Membership section of IIMS website. http://www.iims.org.uk/vessel-coding/certifying-authority-examiner-resources/ Surveyor is to complete the forms as stated in this manual. Surveyor sends original documents (Application and tonnage Survey) to IIMS HQ along with application fee. Currently (November 2016) this is £85 for UK and £105 for all other Flag states. To expedite the process it is a good idea to send an email copy of the survey for scrutineering prior to sending the original Tonnage Survey documents to [email protected] The documents are then sent out by the CA department to a scrutineer. On approval the original is signed and stamped and the original documents are sent to the relevant Flag State registry. Once the Tonnage paperwork meets up with the Registration documents and all is approved, the Registry will issue a Carving and Marking Note. For pleasure vessels the C&M can be signed off by the vessel owner. For Commercial Vessels, the C&M requires to be signed off by a Surveyor after re-visiting the vessel. The Original C&M should then be sent either into the CA for ‘stamping’ prior to sending on to the Registry or directly to the Registry by the Surveyor. Page 5 of 19 IIMS Tonnage Survey Manual - Jan 2017 V3 © IIMS CERTIFYING AUTHORITY 2017 Information required for completion of the certificate of survey All information should be Typed / Hand written in BLACK ink with BLOCK CAPITALS. Measurements should be in metres to 2 decimal places. e.g. 13.56 not 13.6 Tonnage should be to 2 decimal places. e.g. 22.49 not 22.5 Figures for measurement and tonnage should be rounded up or down to the nearest one hundredth. e.g. 22.495 = 22.50 or 22.494 = 22.49 NAME OF SHIP To be entered exactly as it appears (or will appear) on the vessel. Do not use ‘Quotation’ marks or any other surplus punctuation marks.

HIN/CIN: The HIN (Hull Identification Number) or CIN (Craft Identification Number) should consist of 14 consecutive characters visible on the starboard outboard side of the transom, or near the stern within 50mm of the transom top, gunwale, hull/deck joint or its capping, whichever is lowest. Example; FR–SPBDB430 G617 FR = COUNTRY CODE (FRANCE) SPBDB = MANUFACTURERS CODE 430 = HULL or MANUFACTURERS NUMBER. G6 = MONTH & YEAR HULL MOULDED A = JANUARY B = FEBRUARY, C = MARCH ETC. THIS ONE IS JULY 2016 17 = MODEL YEAR …2017 YEAR BUILT: Only the year built should be shown. This is not the model year, see example above for vessels with HIN / CIN numbers. E.g. Enter as 2016 not 16 or 6. Page 7 of 19 IIMS Tonnage Survey Manual - Jan 2017 V3 © IIMS CERTIFYING AUTHORITY 2017 CONSTRUCTION MATERIAL: Enter one of the following; WOOD. STEEL. GRP. FRP. ALLOY. CONCRETE. TYPE OF SHIP: Enter one of the following; SAIL. MOTOR. SAIL & MOTOR. DUMB. SHIP POWER: SAIL. STEAM. MOTOR. OUTBOARD. If the vessel has two forms of propulsion e.g. Sailing vessel with auxiliary engine, both SAIL and MOTOR should be circled. OPERATION: For a non-commercial vessel it should be ticked PLEASURE. For commercial vessels the type of ship should be ticked COMMERCIAL. BUILDER NAME & ADDRESS: Enter name and address of builder. If the vessel has been moulded/built by one builder and fitted out by another, enter the names of each 1. BUILDER: 2. OUTFITTER: MEASURERS NAME, ADDRESS, PHONE NO. & SIGNATURE: Give full details including country code if outside the UK. DATE OF SURVEY: Enter DD/MM/YYYY that the measurement was carried out. e.g. 21/02/2016 PLACE OF SURVEY: Enter town only. e.g. Chichester not Chichester Marina. If outside of the UK then include Country e.g. Antibes, France. Not Antibes. Measurement interpretations LENGTH OVERALL Means the distance between the foreside of the foremost permanent structure and the afterside of the aftermost permanent structure. Moulded bathing platforms etc. that form part of the hull structure and are open to the main hull should be included. Bolt on platforms, bowsprits etc. should not. A good rule of thumb is, if the appendage was removed would it leave a large hole to the hull. If the answers YES then it should be included. Page 8 of 19 IIMS Tonnage Survey Manual - Jan 2017 V3 © IIMS CERTIFYING AUTHORITY 2017 Aft Measurement Point Forward measurement point. LENGTH Means the greater distance of the following distances; (a)the distance between the fore side of the stem and the axis of the rudder stock; or (b)96 per cent of the distance between the fore side of the stem and the aft side of the stern; the points and measurements being taken respectively at and along a waterline at 85 percent of the least moulded depth of the ship. In the case of a ship having a rake of keel the waterline shall be parallel to the designed waterline; The LENGTH should be given for all vessels that have a LENGTH OVERALL of 24m or over.
