RB Admits he has two feet in his mouth!!
"Jeff" wrote in message news This is a truly pathetic display by you, Bob. You made a blunder and then you've spent the last two days backpedaling and changing your story around. You've gone so far as to claim that you're the victim, even blaming it on your friend. But you seem to have settled on the story that when you said "to Windward with a VMG of 6 knots" you really meant that the VMG was measured to some random point, not directly upwind, and not ahead. And you've claimed that this is a perfectly reasonable and common way of describing your boat's performance. However, this is total nonsense and continues to demonstrate that you really don't understand the terms. Here's why: You could have simply stated with your video that you doing doing 8+ knots on a close reach - some may have bought it, others might be skeptical, but its within the realm of physical possibility. But you chose to be clever, trying to use "sailor talk" like VMG. It would have actually been interesting if it were real. Unfortunately, you picked a speed that is not physically possible, especially when supported by a video of you footing off, and I called you on it. You then proceeded to give us lots of double talk and conflicting stories, and finally settled on the lame story that it was VMG to a random mark. But this is nonsense! The VMG to a mark is of no use whatsoever except as a temporary local reference. Even then its use is almost entirely when beating to windward and speed is being balanced against pointing. It has no value when reaching. I suppose there might be some value when working a current, or some other complex situation, but your friend probably used it only because the GPS was set up for racing so that's the value it displayed. Even though VMG to a random mark may have some temporary value in racing, it has absolutely no value when describing a boat's performance, and if that was your actual intent, as you claim, it demonstrates a total lack of understanding of the concepts. Without stating the exact location, it says nothing about boat speed, which could have been as low as 6 knots. And even if you did give the location, no one would actually bother computing the speed, except in the trivial (and interesting) case of the mark being directly upwind. So what is it Bob, were you lying by implying VMG to Windward, or just an Idiot who doesn't understand the meaning and use of VMG? Both! SV |
