With China, India, Japan, and the US putting increased strain on a gas supply infrastructure that is unstable at best, these price increases and fluctuations are here to stay. While modest increases might not keep me off the water, it could have an impact with the purchase of my next boat, opting for a single instead of a twin. I put a lot of hours on the boat each year and I don't have a bottomless wallet. If it ever hit $5.00, that would mean a $500 fill up @ 100 gallons. Doing that once a week or at best once every other week would definitely affect my boating lifestyle. I guess I'm not as fortunate as those posting above, but at prices close to or near double what it is now could put me out of boating, at least high performance. The good news is that nobody is predicting prices that high, but significantly higher than normal is not out of the question in the next few years. Bottom line...will it affect my boating lifestyle in some manner? Definitely YES.
