Guys,

It's exactly the very slight flexing of an "H" type tilt bed that can damage the beams. When you support the hulls in snug fitting cradles where the cradles are connected by metal beams...any bending along the lateral tiltbed beams will tend to cause the cradles to pry the hulls apart in a direction that the hull/beam structure is not designed to handle. Even very slight bending can do damage and over many trips, this can(has) lead to boat failures.

Our hanging-from-the-mainbeam concept eliminates this risk entirely, since flex of the trailer cannot be applied between the two hulls. THe mainbeam is quite close to the balance point, so any windage or road bump loading on the ~80 lbs lifted hull should be easily handled by the structure. A structure designed to slam into waves and come to a rapid stop from 20+ kts speed (easily hundreds of lbs loading) is not going to be affected significantly by 60 mph winds from straight ahead while driving on the freeway. Many of these mainbeam support designs were built in the 70's for Tornados with no reports of problems.

Mike.
