Our last post before Xmas so Merry Christmas and a very Happy New Year. Next year we'll be finding new areas in the Greek Ionian to cruise as well as spending more time in Albania, central to northern Croatia, Venice and the east coast of Italy - so there will be lots of exciting things to read about.
Meanwhile we still have plenty of cruising matters to post.
Envoy is currently in Lefkas marina for the Med winter.
This posting is all technical.
Before leaving Envoy to return home to Auckland we do all of our normal lay-up procedures including running fresh water and then glycol through the generator, wing engine and all seawater cooled pumps. The main Lugger engine doesn’t need this as it’s cooled with a keel cooler, so no sea water is used.
The generator’s leaking sea water circulation pump, last re-built 2 years ago was stripped and new bearings, seals and impeller fitted. But on re-installation and testing it still leaked so it was removed again and the “shaft modified” - exactly how or why was lost in translation, but this has fixed it.
We replaced two below water level seacock hoses. These were both polyester yarn reinforced pvc hose and apart from the fact they were over eight years old, pvc is not recommended for use below the waterline. These have been replaced with new stainless steel wire reinforced pvc hoses which will be much stronger and which Sailand say are commonly used below waterline in Greece. I have some reservations about using any form of pvc (a long term problem is embrittlement caused by the pvc’s plasticiser leaching out) but for one of the seacocks the default position is off, and the other it is easily accessible.
We towed our large RHIB in to the marina so that it could be taken out of the water for a full service of the Yamaha outboard, service of faulty bilge pump and to get a new sounder transducer fitted.

We organised some jobs to be done while we’re back in New Zealand:
- The Lugger alternator rumbles when spun by hand, even though the unit was re-built last winter, so this will be checked. Sailand think the problem is with its shaft, not bearings
- The Lugger’s gearbox oil will be changed and suction strainer cleaned
- The Lugger’s prop shaft coupling and shaft alignment will be checked
- The Lugger’s two interchangeable Racor fuel filters will be removed, cleaned and have their drain seals replaced
- The wing engine has developed a little rust on the fuel pump and adjacent fuel lines so this will be cleaned up as well as checking the source of the corrosion which appears to be from small amounts of salt water dropping down onto it
- The wing engine’s mountings will be renewed
- The air cleaners and cooling hoses on all three engines will be checked
- The generator’s starter motor and solenoid will be serviced and its cooling system including the exhaust elbow will be cleaned and checked
- A hairline crack in the GRP base of the main shower will be repaired
- The electric windlass motor will be removed and checked
- Nikos of Ionian Safety now tells us (contrary to what he said in April) that he can certify our Halon-based engine room fire extinguisher, and will remove it for a thorough visual and weight check. Although Halon can no longer be used (for environmental reasons), Nikos believes it’s still the best system but Halon extinguishers can’t be refilled so eventually ours will have to be replaced
- The s/s wire strop that we use to lift our large RHIB (weighing about 320kg) out of the water is being renewed with a strop made from Spectra (ultra-strong plastic rope)
