Look at the tri's stored
on the hard in
san carlos, they build a
cradle on a mobile home frame typically, and support weight at the beams most commonly. I've also seen a
wharram on 2 separate trailers , with an elaborate tongue to connect them together,.. along the train of thought like it seems Cat Sketcher mentioned. Personally I don't know anything about the
lagoon bridgedeck strength, but as long as your cradle/beam supports distribute the weight to main strength bulkheads- should more likely than not be fine. Then once you get to the yard put extra jackstands/support under the keels for longer term if needed. Looks like the lagoons are delivered or moved by bridgedeck in this case:
