LARGE - FRAME LIVING BOAT

The present invention relates to a wide hull lifeboat according to the preamble of claim 1.

FIELD OF THE INVENTION

Existing lifeboats, due to the rules and traditions, are of general arrangement, without toilet facilities, where persons are placed on one level of the lifeboat, within the limits permitted by the height differences of the benches and the seating only when the boat's pilot is seated higher.

Each seating position shall be reserved for the permitted number of persons: a total depth of 600 mm and a width of 230 mm at the back of the seat and 300 mm at the knees.

Increasing the permitted number of people will require increasing the length and width of the boat, which will result in increased boat deck space and the need for boat deck length on board. The rules require lifeboats on both sides of the ship, according to the number of crew and passengers. According to the rules, the maximum number of people allowed on a lifeboat is 150.

The wide-hull lifeboat of the invention requires less boat deck space, reduces the disadvantages of the safety of marine life-saving appliances, and achieves the following advantages: This object can be achieved by placing persons on the lifeboat on two or more superimposed deck levels.

* ·. * 1 The main advantage of this invention is that by increasing the width of the lifeboat only: a wide hull reaches sufficient safety stability, including the lifeboat: *, · with a permitted number of persons loaded at several deck levels it is possible to jump up to the deck if the wave fills the lifeboat, because::: now at least in open lifeboats there is no bench above where you would even stand.

The deck area required for lifeboat seating is reduced by up to V · 'when there are two or more deck decks and the number of persons permitted.': '. increases accordingly.

By minimizing the amount of freeboard required by lifeboats for their overall length, '·. · At least passenger ships have the economic advantage of gaining valuable value for productive use! deck areas and open ocean views or window length windows.

Large cruise ships need eg 26 lifeboats of 150 persons: wide hulls are suitable for a shore length of about 40m or, in the future, it will be possible to build 300 lifeboats of only 150 hulls instead of the existing 150 lifeboats.

The wide hull lifeboat allows you to minimize the boat's own weight, save on materials and costs, as hull thicknesses are increasing in relation to boat length and lifting hook spacing. is strong for width strokes.

In covered lifeboats, the wide hull also shortens the margin. In the combined liaison and lifeboats of the cruise ships, the window visibility is extended and the large-hulled lifeboat can accommodate toilets and toilets.

The wide hull lifeboat of the present invention is characterized by what is set forth in the preamble of claim 1.

The invention will now be further described with reference to the accompanying drawings and sectional views, in which:

The invention is not limited to the following general arrangement or cutting arrangement, but many modifications are possible within the scope of the inventive ideas defined in the appended claims.
