Case study: Wooden Motor Yacht

The following defects were noted on a Wooden Motor Yacht:

  • The boat has at some time been grounded and temporary GRP sheathing repairs made to the keel. These repairs are now breaking away and the exposed wood of the keel is weakened by rot in a number of places.
  • Planking around the rudder tube has been subject to rot and internally it can be seen that water has been seeping in.
  • The port side ‘P’ bracket is loose and will require securing, this will necessitate the removal of the port fuel tank to gain access internally. With the aid of a mirror It can be seen that water has been seeping in around the fastenings and may have allowed rot to develop in the adjacent wood.
  • Low grade gate valves have been used for the sea toilet intake and the galley grey water discharge. They are both badly corroded and seized. All other seacocks are seized.
  • Water leaking through the deck around the two cleats on the foredeck has weakened the deck beam through which they are bolted, it is likely that these cleats will fail and pull through the deck if the boat is left on a mooring and they are placed under even a modest load.
  • Water leaking in around the hatch on the aft deck has rotted the upstand and penetrated to the plywood sub deck and adjacent deck beams and carlings, this has substantially weakened the aft deck.
  • Wood around the grab rails on both sides of the coachroof has been weakened by rot where movement has allowed moisture to enter via the grab rail fastenings.
  • The starboard engine exhaust hose is degraded and has collapsed internally.
  • Both steel fuel tanks are extensively corroded externally as the paintwork has only maintained on the two sides easily visible from the engine bay kept.
  • The gas canister is not in a suitable gas locker with a drain but instead is located in the engine bay between and within inches of, the diesel heater and an electrical switch panel. This is extremely dangerous.
  • The painted side lining above the galley stove has scorched due to heat from the stove. The gap between the stove and the lining is insufficient and without a heat deflector is a serious fire hazard.
  • The vessels electrical system has been added to and components by-passed over time and is chaotic with cables draped into the bilges and unconnected wires dangling in mid air. The switch panels are largely unlabeled and many of the components were not seen to function. Two of the three domestic batteries are fully discharged and will require replacing.
  • The vessel has a 230v shore power ‘system’ installed, there is no RCD or circuit breakers incorporated and the system is therefore not to a safe modern standard and should not be used until it is upgraded.
  • Plus a large number of less serious defects.
