Why attribute "tacking in front of another vessel" to
blindness? Could it be a windshift, shoaling water, engaged
in racing?

Ok, quote the rules, from the federal regs, that clearly state those reasons
justify making a sudden turn into the path of another vessel, without giving
any sort of audible sign.

If you had a clue, you wouldn't think that sailboats "tack
blindly" or at random, much less think they were under any
obligation to keep clear of motor vessels.

Why is it ragbaggers always want to jump in assuming they somehow know
better? Just as often they're completely incorrect, not only about the
rules but also the level of knowledge about the other people posting.

There's enough idiocy around without the stereotypes, no?

Then why be such an idiot? You only perpetuate the
stereotype of motorboaters.

You often nothing here other than insults, my how typical.
