Am enjoying this thread a lot - love seeing custom modification & fabrication projects like this. I am thinking of modifying my trailer to allow easier launches from awkward locations, particularly soft sand, mud and shallow angle areas, but there are 2 main challenges that I can see.
The first is that I want my road going trailer sturdily built to handle rutted out back roads, resulting in a boat trailer combo that is fairly heavy (not so good on sandy beaches mud. The second issue is that I want a plenty of clearance under the trailer frame to keep it from getting hung up on rutted roads. This means that the boat sits up fairly high and that this is accentuated by the tunnel hull design (as it would also be with a futura hull). This high positon is OK with reasonably graded launching ramps, but does not work well at locations with a shallow slope into the water. There are 2 options that I'm considering other thing
The first is to set up the roadway trailer as a slightly modified flat deck with tracks that accomodate a lightweight aluminum framed trolley with beach balloon style tires. "Rogan" has a picture that pops up as one of the alternating photos on the home page of this site with a really nice beach cart for his futura (a Mk II I believe). It has 3 pairs of those "wheeleeze" polyurethane balloon tires (~19" diameter) which should float quite a bit of weight over soft sand. It was something like this: http://www.atlanticjetsports.com/roleez.htm
The second is to use a fairly similar flat deck trailer as previously described but with removable ramps at the rear for transom mounted launching wheels such as these: http://www.beachmaster.co.nz/
and having a set of front beach wheels such as the ones in the picture (below) under the hijackers near the front to support the weight of the bow. In this case I would need some sort of hump in the center of the flat deck trailer that would support the floorboards of the boat. What I like about this second option is that the front set of wheels could be easily disassembled and stowed in the boat for traversing trails between lakes, getting around large dams on major river systems etc...
