In case you are looking for a haul-out facility for a catamaran
( max 45 feet loa, max 16 Ton),
please take a look at the next pictures...
Pictures showing a Lagoon 42.
( a Lagoon 45 also used the trailer, but is top-limit).
This might be the one and only purpose built
catamaran trailer in Japan.
Between 2 hours before and after high-tide
the boat can be hauled/launched.
