Well, I'm now on my third return trip since last October and have resisted posting my experiences until now.
My conclusion is quite simple… There's nowt wrong with the vessel and here’s why…. I think by now the Masters have got used to the way the Manxman handles and are gaining in confidence with every voyage, particularly manoeuvring in the harbours. Case in point was last Sunday’s 08:45 departure and the subsequent entering of Heysham. The Master had her about-turn and approaching the ramp stern first within about 7/8 mins of entering the harbour. Yes there was vibration but you would expect that from the thrusters, the same happened on the BMC. I reckon I drove off the ramp within 20 mins max of entering the harbour, which was about the same as the BMC.
The more voyages the Masters & crew have under their belt the slicker the whole process will be.
