This Riviera 4000 Offshore recently came out of the water for a scheduled antifoul.
On the previous sea trial, we suspected growth on the running gear as we were unable to achieve target RPM and experienced planing struggles. Haul out was scheduled as we were correct in our guess
we identified significant barnacle growth on the running gear, which was having a noticeable impact on the vessel’s performance. While the boat was out of the water, we also carried out a number of repairs within the bilge, including rectifying oil leaks faulty ball valves and steering repairs.
Following the repairs, antifoul and a full sea trial, the results spoke for themselves.
Before entering the workshop, the vessel was cruising at approximately 18 knots. After completing the work, cruising speed increased to 24 knots, highlighting just how much of a difference a clean hull and running gear can make.
Regular maintenance below the waterline and inside the engine room is often overlooked, but it plays a critical role in maintaining performance, reliability and fuel efficiency.
