Classification

All Watson series vessels are designed in accordance with Classification Society Rules and Regulations as required or if requested, and designed from first principles. The in-depth design expertise; and this is what really successful construction relies upon, is more than adequately taken care of with the in-house design staff which can draw on many years of development of the present series but also involvement with a multitude of vessel types and designs over many years. This experience we believe gives unparalleled solutions to the “not normal” aspects often encountered during vessel design and build projects.

The discipline forced by engineering to the exacting standards imposed by a Classification Society is easily shunned. Yet everyone, from designers, builders, owners and particularly yacht brokers love to include Lloyds name in conversation or advertising about their boat or product. The prestige it invokes is irresistible. 

Unfortunately, due to a lack of knowledge the tendency is to over state the merits of the vessel, usually along the lines of “built well in excess of Lloyds Rules” which is of course completely meaningless. A yacht is both designed and built to a known standard or it is not; pure and simple. To hear a vessel described as using Lloyds or ABS as “base” is to know immediately that the name only is being adopted. 

Often overlooked is the economic value that classification contributes. The selection of machinery and equipment is, due to the rigorous requirements of any Classification Society, always of the highest quality and, having been demonstrated to their satisfaction is “fit for purpose”. 

It is our contention that any vessel, especially one intended for ocean crossing, should be built to comply with some recognized standard. We consider this to be the very essence of any claim of quality and safety. After all, not only are we are talking about a large financial investment, but also, and this is our priority; the safety of the crew. 

Classification is in effect a “Peer” review of the highest order to internationally accepted standards for ship construction. Due to our more than sixty years of experience with Classification Society Rules we are used to dealing with the eccentricities and discipline these impose. All our craft are offered built to a classification society standard, with the absolute minimum being Lloyds Special Craft Rule. 

These Rules are ever changing as they rely on empirical evidence; they are derived from the study of "real world" incidents and accidents, with particular attention to where loss of life has occured. As a set of rules they have been in development for over 200 hundred years, or for as long as the particular society has been in existence; Lloyds Register 1760, Bureau Veritas 1828, Germanischer Lloyd 1867 and American Bureau of Shipping 1862, being the main Societies. 

Generally there are two sets of rules; Yacht Rules and Ship Rules. For the steel construction used in the Watson range of passage makers we use the ship rules. These rules not only cover hull construction and material selection but also machinery and systems design, construction and installation. 

With our passage maker range, being ocean capable craft, we are looking to build to the highest standard we can, producing a quality vessel with outstanding capability. The customer can be sure that we are doing our best to ensure not only a successful vessel but also their personal safety. 

To fulfill these requirements we complete the following:

• Submit the complete detailed design for the vessel to the Classification Society, for review and approval. 

• Provide calculation sheets demonstrating the shear and loading for all structural parts of the vessel required for review. 

• Construct the vessel using classification “type approved” material and fit approved machinery and systems, including electrical.

• Subject the vessel during construction to any inspection or material test required by the Society’s surveyor. 

• Conduct an inclining experiment with the completed vessel and produce a Trim and Stability Data Book for review and approval.


No other builder offers this standard of care in the design and construction of small passage makers.
