BM -
The issue occurs when the launch becomes a major "take-out" with lots of traffic.

When I return to the launch and see a boat at the end of the finger pier am I to assume that it is ok to park in front of that boat as I retrieve my trailor or should I look for one where I can get in "line".

Nothing messes up a orderly take during busy times than a boat out of line along the loading dock for those looking to load their boats without driving on.

I understand how your method is the best for you in terms of getting a quick exit and it should work great when there is empty dock space. However if all/most the docks are in use it can slow things down for the "fleet".

Just my thoughts as an gray beard that fishing alone a lot.
