Just a warning in case you are ever told that there will be an Austal Fast Expeditionionary Transport Craft docking
Friday, was informed that one would dock
early Saturday in front of me at the adjoining shipyard.
They warned me that the US Navy Captain
likes to dock
without tug assistance and to prepare for jet wash
Being anchored stern to dock I laid out an extra heavy breast line 50m to starboard pier where ship would dock
I tighted up both anchors hard (100 M and 70m out after doubling up on stern lines.)
As an afterthought I also ran 2 heavy mooring
lines to my stern quarters from nearby mooring
blocks to relieve stress and back up the anchors.....(Little did I know that those would save me)
Early next morning while he was backing in we lifted gangway
and pulled away from pier a few extra metres
The 4 Wartsila jets on Austal ship are huge and the wash is likewise!
It sounded like he was using dynamic positioning to maneuver which meant heavy power to opposing buckets to keep it on rails.
As he got closer his jet wash was scouring up the bottom (40ft deep) and blowing my anchors and chain sideways.
The amount of mud lifted from bottom was incredible and it was only those heavy lines from my stern leading forward to mooring blocks that kept me off the pier.
with that power wash took about 35 minutes and was very stressful.
No damage and luckily I had closed up all my intake and discharge thru hulls beforehand
Unfortunately other boats not so close, had Aircon pumps and plumbing
choked with mud and debris from his bottom scouring .
Amazing vessels these heavily powered Jet boats should really allow tugs to dock them when near smaller craft!
