My last boat drew 5'4" and when it went aground on that big wing keel it was stuck good.
My new boat is the deep draft
verison of 6'4" and has never been aground, but I'm sure I will have a better chance of getting it off the whatever!
But while both boat sailed in normal conditions just as good; when the wind
picks up and gusts are hitting you the deep draft ready stands up better.
I would never go back to a shoal draft unless it was a swing keel. Sure there are some places I wouldn't go, but hey I probably wouldn't have gone in those with the shal draft either. How much risk are you going to accept to get into water
1.5' shallower instead of anchoring
where you are safe?
