First two are Mulders convertible. nice boat, not so nice audience around it
Third one is one of my favourites, the Nolimit from Groningen Netherlands. It's a carbon copy from the lifeguard boats in the netherlands, but the interiour is all yachtbusiness as usual, so, best of two worlds, a truly go anywhere; you'll need a nuclear device to sink one of these...
Another favourite of mine is the small ONJ Pilot, which also is a copy from a commercial vessel, from Mulder en de Rijke who build a lot of government stuff.
Cheap too, since you pay about €65000,- for a boat with good sleeping accomodation, a kitchen, seperate toilet and inside and outside steering.
