We use a stopwatch for competition times the watch is started when the clock hits 0 not when the boat crosses the start line, so a good start is very important. We use timing lights for 2 lap and strait line events. We keep times on all the heat races as that is how we break a tie in the points. In NAMBA any record set with a stopwatch expires in 3 years just in case the stopwatch operator made a mistake.
I see that so far two say they have run a 75 sec heat race I sure would like to have them post some more info. Like where ,when, hull, motor, prop...I have seen that done only once and that was under perfect race conditions by the fastest Sport II in NAMBA. I am surprised that there are two that are on this board that have accomplished that. Come on guys how about giving up some details?
