6 days, about 70 miles or so. I was in the Apostle Islands Lake Superior. Excellent crossing speed. Fairly nimble for sea cave exploring. Glad I installed the skeg kit from Superior. The Invisible Hatch Hold-Down Kit still has the jury out on it. I'm going to try some rubber tape as seal material vice the foam the kit provided. That had to be trimmed to have the hatch become flush with the deck surface and they leaked excessively. I was duct taping the seam while cruising for the day. I hope to get them functional. Regardless had a great time.
