Those capsize numbers have a bit more meaning to boats that are actually capable of (or contemplating, or dreaming of or wondering if they are capable of) venturing afar offshore and realistically anticipating heavy weather that they cannot outrun - a category into which your boat does not fit. What it is, is a great trailer/sailer built for the nearest lake or bay - just enjoy it for what the manufacturer says it is "...makes it a good boat for novices at sailing". Could you take it across the Gulf Stream, sure, you could go in a sailing dinghy - with a lot of sailing skills, a modicum of luck and no bad weather.
When you're ready for offshore sailing there are a number of small boats that can serve you well - however, many of them are not trailerable.
