I've got as KATO arch that sits higher than the factory-installed davits. I use the low davits for day sailing
, and, after stripping the dink completely of oars, engine
, etc., use the KATO arch davits for passages. I lift
90% to blocks, and then use diagonal ropes. If bow of dink is on port side, I run line from bow to starboard stern railing, and then stern of dink to port stern railing.
I also run 2 lines from the sternward-facing edge of the sideways dink over the arch and then secure to stern railing. This tips the dink so that following seas hit its bottom, and not fill it.
Then I lift up the remaining 10% and snug it against the s/s arch. It rides about 6 feet above the water at its lowest point, and so far, with 20 foot following seas and 35 knots of wind
, no issues.
I might also be tempted, if facing contrary winds or currents, to just deflate the darn thing and store in the cockpit
