ok according to Brian his new Simrad GPS had him a couple of hundred yards past the end of the jetty. he hit about 75 yds before the end. Sea Tow guys said they've pulled several boats off almost the exact same spot over the yrs. he was going about five-ten mph because it was rough.
Possible, if charts are inaccurate or he may have had map datums not set right. If his GPS is set to a different datum than what the dowloaded chart is using, he could be off quite a bit. But I'd think he'd see that well before it became an issue like this?
