I'll Take a Stab....
Not knowing too much about the Daysailor, or its underwater hull shape, I'll compare it to my OD25 and its trailer set-up. Hope this can help:The trailer has a keel pad that supports the greater share of the hull weight. It also has an keel slot guide, made from angle iron, that coralls the keel guiding the hull on to the bunks (2 X 12). The bunks are 2/3 the water line length (12'), and are mounted on swivel jack pad stands, 2 per side. Once the keel has been captured, the bunks lock the hull in place and its just a matter of winching it forward to the bow support on the trailer. The secret though is that keel slot angle iron. Any chance one could be added to your trailor?DonDon
