Frequently asked
Questions owners and captains ask.
Clear answers on where we work, what we work on and how an engagement runs.
Which engines and systems do you work on?
All major marques in diesel and petrol, including Caterpillar, MAN, MTU, Volvo Penta, Yanmar and Mercury MerCruiser, together with the gearboxes, generators, hydraulics, electrical and air conditioning systems around them. If a specialist or factory technician is the right call for a particular fault, we will tell you and coordinate it.
Can you manage a haul-out or refit end to end?
Yes. We coordinate the lift, hardstand time, antifouling, detailing and other trades alongside our own mechanical and electrical work, so there is one point of contact and one schedule. Owners and captains get progress updates without having to chase each contractor.
What happens if something fails at short notice?
Contact us directly. Vessels with a charter, delivery or owner program on the calendar are prioritised, and we will typically fault-find and either resolve the issue or have a plan and parts on order the same day.
Can you set up a maintenance program for a vessel or a fleet?
Yes. Programs are built around engine hours, usage and manufacturer service intervals, with scheduled servicing, inspections and reporting so nothing is left to memory. For commercial and charter operators this also keeps survey and compliance records in order.
Do you provide reports for surveys, insurers or a purchase?
Yes. We carry out pre-purchase mechanical inspections, condition reports and insurance-related assessments and repairs, with documentation written to the standard insurers and surveyors expect.
