JPS61129389A - Boat form of high speed boat - Google Patents

Abstract

PURPOSE:To aim at reducing the rolling of a boat upon stopping or low speed cruising, by providing such a suitable boat form that the boat width is discontinuously and abruptly increased directly above the water plane, having the same width as that of a deck. CONSTITUTION:Boat sides are formed such that the width of a boat is discontinuously and abruptly increased just above the water plane WL of a water line width B, and therefore the width is set to be the same width as the width A of a deck with this width A being maintained to be unaltered up to the deck. When the boat is inclined, the water plane WL' passes through parts of the boat sides where the width of the boat is abruptly increased so that the water line width is increased to abruptly increase the recovering force. Therefore, with no necessity of specific measures, it is possible to aim at reducing the rolling of the boat upon stopping or low speed cruising.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a high-speed boat dock. [Prior Art] Conventionally, a high-speed boat dock generally has a deck width At, as shown in the perspective view of FIG. 3, for example. -For the purpose of ensuring safety and reducing Bl at the waterline due to propulsion resistance, it has an inverted trapezoidal shape with the bottom cut out, but since the hull of a high-speed boat is lightweight, it can be Sometimes when subjected to transverse waves, etc.
The disadvantage is that the horizontal vibration becomes large.

Therefore, various means such as foldable anti-rolling boards have been proposed, but all of them require special equipment and increase weight, so they cannot be said to be optimal for high-speed boats.

[Problem that the invention seeks to solve]

The present invention was proposed in view of these circumstances, and
It is an object of the present invention to provide a high-speed boat dock which does not require any special equipment and which uses the dock itself to prevent rolling when a boat is stopped or when sailing at low speed. is discontinuous from just above the water line position;! The ship's width was drastically increased, making it almost the same width as the deck width, and was then characterized by having a ship side that maintained almost the same width all the way to the deck.

[Effect]

With the above-mentioned structure, it is possible to obtain a high-speed boat dock which does not require any special equipment and which prevents the ship from rolling during stopping or low-speed navigation by using the dock itself. To explain this, FIG. 1 is a perspective view seen from the 7th seam, and FIG. 2 is a cross-sectional view showing a case where the dock in FIG. 1 is tilted.

In the above figure, the same symbols as in Fig. 3 respectively indicate the same parts vf as in the same figure, and 1 indicates a sudden increase throughout the ship discontinuously from just above the position of water line WL in water line B. , almost on deck A
3 is a high-speed boat. 〇 In such a high-speed boat, mid-deck A and mid-waterline B are the same as those of a known high-speed boat, respectively. This is the same as B, but as can be seen from Figure 2, when the high-speed boat 3 leans to either side, for example to the right, the water line WL' rapidly increases the width of the side 1 and covers the side part, causing the water to fall. Since the water line B' is larger than the water line B, the stability increases rapidly compared to known high-speed boats.

Such high-speed boats do not require any special equipment;
The Type 8 itself has the effect of reducing rolling when the ship is stationary or sailing at low speed.

〔Effect of the invention〕

In short, according to the present invention, the ship's width is rapidly increased discontinuously from just above the waterline position, and after making it approximately the same width as the inside of the deck, the ship's width is maintained at approximately the same width all the way to the deck. 1. Because a high-speed boat shape is obtained that does not require any special equipment and prevents rolling during halting or low-speed cruising due to the hull shape itself.
The present invention is extremely useful industrially.
