John,
We have a twin axle trailer suitable for a twenty-four foot lift keel yacht if that would be suitable? We live close to the Lakes so could bring the trailer up this weekend if required (any day would be fine, we're usually around anyway).
Our boat (Jeanneau 24.2 Seas the Day) is currently for sale with Maiden Marine and there are a few pictures of the trailer on their Brokerage site if you want to have a look. The trailer has adjustable support legs as well as a tray for the keel so I think it should be okay (keel up).
Regards,
Dave
