The truth hurts.
I was a commercial seaman for 20 years. Ships navigator. Yes, I well know racers expectation is for every one else to do the courteous thing and go around their race. Even if it forces 700 foot ships into the rocks.
The courteous thing to do would not set up race courses in busy harbours, channels, ferry routes and commercial shipping lanes. But no, its every one else who is supposed to be courteous.
I don't know how many times I have had to alter ships courses in designated channels while some red faced beered up racer screams "can't you see I am racing here.".
Painting all racers with such a broad brush based on your experiences negates your experience.
I am sure there are quite a few "Wyatt Earp" large boat operators as well as navigators. Maybe even some of their fopahs have been documented as they crashed into other ships or fixed objects like rocks. I would not expand that to mean all large ship seaman are less than competent bullies using their large ships to demand the right of way. I have been bulldozed out of the way by a few tugboats pushing barges as they charge through groups of fishing or sailing boats on the Chesapeake when a small course deviation miles before would have seen them cruise the edges of them.
My experience has been the contrary with both groups being poor seaman or rules followers . Most exercise courtesy.
Racing in most cases I have seen ultra teaches most sailors the rules of the road. The first being of course safety of your crew as well as a other boats,
Many large ship seaman have great manners as both boats share the same waterway together. I have talked to many captains over the VHF on the Southern Chessie and off shore when contacted by them when we have crossing paths. Most are extreme professionals and make suggestions as to their or my boats movements to avoid any possible collisions.
Sounds to me you thought you as. commercial vessel believe you had ultimate rights of the water with small sailing vessels you contacted, thus your apparent bitterness to a few instances where a few racers crossed your path bringing out your ire.
Personally I don't force a larger less navigable ship to charge it's course in close quarters.
