Survey for the prospective buyer comprehensively detailing the condition of the vessel.

It is normal for your insurance company to request this prior to insuring/renewal. Similar to the pre-purchase survey but slightly less onerous.

From small custom component designs to a full 'as fit' set of engineering drawings for your vessel, or perhaps a redesign of your deck layout, or a new steering pedestal.

Alternatively we have the capability to produce a working 3D model and full set of build drawings.

Advising and representing the owner in the scope of refit to be carried out. Conversing with the yard to produce exactly what is requested. Producing detailed repair specs with engineering drawings

Years of coatings and antifouling are removed from the hull in select areas where inspections are carried out to find signs of moisture related defects & areas of high moisture content. The treatment process can be specified and managed.

A survey can be tailored to your requirements if you have a particular area of concern. Let me know what area you want an expert impartial report on.

Representing the prospective owner anytime throughout the process from initial specification, through build, then onto commissioning and handover.
