I have four evaporators and two compressors that produce a lot of condensate and all used to run into the bilge. The evaporators drain under gravity, mostly to the shower sump or back to a compressor tray. The compressor trays are too low down to gravity drain so I use Sauermann Condensate Pumps...

Bow thruster before stern. Hydraulic before battery. One thing I've learned recently with my Wesmar Hyd. Thrusters is cleaning the back (inaccessible), side of the counter rotating thruster props is essential. Any barnacle, even when just on one side of the blade, makes them useless - lots of...

Agree with 90% of the above. Other points of interest - not yet mentioned: Cylinder needs a 10Yr Hydrostatic Test In Phuket I can get the yearly re-certification done without taking out and weighing. The contractor uses an ultrasonic device to check the flooded volume (the level of liquid inside...
