My main concern was with the Garboard plank and where its seam met the keel; fortunately, this was the first seam to close. After 4 days on the slipway, I was getting impatient. I felt Challenger was not getting wet enough; the receding high tide was having less effect. Therefore, with a large capacity pump I floated Challenger to an adjacent mud berth using warps and lines, allowing her to flood up to a point. As I had done with the Ketch, I deliberately allowed water to stay inside Challenger but this time only enough to cover the bilges so that the lower seams near the Garboard plank were soaked continually when the tide was out.
