    The attached general arrangement, shows the layout of the ship. Passengers should go down the steps to acces the viewpoints, where they remain standing, watching the bottom.
    I do not believe that, at least in my country, is permitted to make a hole in the covers to see the bottom. It greatly reduced the ship's longitudinal strength and, above all, the flooding of a compartment would lead to flooding of the whole ship. As I mentioned in my previous post, the ship must remain afloat even if a room flooded. For the same purpose, in addition, it is compulsory to place a seal, with a coaming of 650 mm, in the scale of access to viewpoints.
    Besides all this, the deck are arranged with tables and seating for all passengers. Our rules require that there are seats for every passenger. And, very, very, important, they sell sandwiches and drinks to passengers, which is part of the boat business.

    This boat has been working for three years. It is fully operational. It cruises between the coast and an island near Alicante (Spain), about 2 hours. Four daily comings and goings. It is about 25 m in overall length, but in the General Arrangement included in my post # 17 you can see more details. Passengers go down the stairs to the "viewpoints local" where they remain standing although it would also be possible to place banks in them. The crystals are in the sides of the hull, very close to the bottom of the boat, so that the seabed is perfectly visible. In one of the boats that I have projected the crystals were in the horizontal flat bottom of the vessel.
    For more information, if you wish, use my e.mail : 657677483@orange.es
