The Keizer 42 is inspired by the traditional runabout, but then with a modern drive line in the vessel's stern. The yacht measures 13.42 metres in length and 3.99 metres in width. These dimensions have been used to best advantage for the practical living space. The huge cockpit with a completely flat floor offers much sitting room, a huge recliner and a fully equipped (outside) galley. The cabrio roof that also makes the yacht suitable for not so nice weather is stored on top of the windscreen. If you go below deck, you will have the feeling of entering a hotel suite. The master bedroom is equipped with two stylish sofas and a king size bed. The fully equipped "head" does not know what "concessions" are. As is the case in the master bedroom, the standing height here is also 1.90 m. There is a guest hut on the stern of the yacht with two beds and sufficient cupboard space.
