【発明の詳細な説明】
本発明は、高速艇の船型に関し、特に後部船体
の形状に特色をもつた高速艇の船型に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hull form of a high-speed boat, and more particularly to a hull form of a high-speed boat having a distinctive shape in the shape of its rear hull.
従来の高速艇では、その滑走性能に重点がおか
れていたため、その船型は幅広型となり、一般に
メタセンター高さが異常に大きく、そのため横揺
周期が極く短くて、海面に僅かな風が吹いて生ず
る波にも容易に同調横揺を起こして、乗心地を著
しく悪くするという欠点がある。 Conventional high-speed boats focused on their planing performance, so their hull shapes were wide, and their metacenter heights were generally abnormally large.As a result, their rolling periods were extremely short, and a slight wind was blowing on the sea surface. The disadvantage is that the waves generated by the vehicle easily cause synchronized rolling, which significantly worsens riding comfort.
本発明は、このような欠点を除去しようとする
もので、高速艇において前進航走時に波を切らな
い船体後部の左右舷側面間を狭くすることによ
り、推進性能を確保しながら横揺性能の向上をは
かつた高速艇の船型を提供することを目的とす
る。 The present invention aims to eliminate these drawbacks, and improves rolling performance while ensuring propulsion performance by narrowing the space between the starboard and starboard sides of the rear part of a high-speed boat that does not cut through waves during forward sailing. The purpose of this project is to provide a high-speed boat with a high speed boat.
このため本発明の高速艇の船型は、後部船体に
おける船底外板の左右側縁が吃水線よりも上方に
船側線をもつように形成された高速艇において、
後部船体が上記吃水線に沿うレベルで上記船底外
板における左右側縁の船側線間の幅よりも狭い間
隔をもつた左右舷側面をそなえ、上記船底外板の
左右側縁が舷側外方へ向けて突出形成されている
ことを特徹としている。 Therefore, the hull form of the high-speed boat of the present invention is such that the left and right side edges of the bottom outer plate of the rear hull are formed so that the side lines are above the waterline.
The rear hull is provided with port and starboard sides having a spacing narrower than the width between the ship's side lines of the left and right side edges of the bottom shell plating at a level along the water line, and the left and right side edges of the bottom shell plating are directed outward to the gunboard side. The special feature is that it is formed to protrude towards the direction of the body.
以下、図面により本発明の一実施例としての高
速艇の船型について説明すると、第１図はその平
面図、第２図は第１図の―線における横断面
図、第３図は第１図の―線における横断面
図、第４図は第１図の―線における横断面
図、第５図は第１図の―線における横断面図
である。 The hull form of a high-speed boat as an embodiment of the present invention will be explained below with reference to the drawings. FIG. 1 is a plan view thereof, FIG. 2 is a cross-sectional view taken along the line - in FIG. 1, and FIG. FIG. 4 is a cross-sectional view taken along the line --- in FIG. 1, and FIG. 5 is a cross-sectional view taken along the -- line in FIG.
これらの図に示すように、高速艇の後部船体に
おいて、船底外板１の左右側縁１ａが吃水線２よ
りも上方に船側線３をもつように形成され、これ
により滑走艇としての性能が維持されるようにな
つている。 As shown in these figures, in the rear hull of a high-speed boat, the left and right side edges 1a of the bottom shell plate 1 are formed with a side line 3 above the waterline 2, thereby maintaining the performance as a planing boat. It is becoming more and more common.
そして、吃水線２に沿うレベルで船の前進航走
時に海面を切る役割をもたない後部船体の左右舷
側面４間の間隔B1が、船底外板１における左右
両側縁１ａの船側線３間の幅B2よりも狭く形成
される。 The distance B 1 between the port and starboard side surfaces 4 of the rear hull, which do not have the role of cutting the sea surface during forward sailing of the ship at the level along the water line 2, is the ship side line 3 of the left and right side edges 1a of the bottom shell plate 1. It is formed narrower than the width B2 between the two.
したがつて、後部船体における船底外板１の左
右側縁１ａが舷側外方へ向けて突出形成されるこ
とになり、この船底外板側縁１ａの補強のため、
その側端と主船体との間に複数個所で補強材５が
装架されている。 Therefore, the left and right side edges 1a of the bottom shell plate 1 in the rear hull are formed to protrude outward from the side, and in order to reinforce the bottom shell plate side edges 1a,
Reinforcing members 5 are installed at multiple locations between the side ends and the main hull.
また船底外板側縁１ａの上に乗る自由水の動き
を制するため、補強材兼用の自由水制止板６が適
宜配設されており、上記自由水が後方に流れて前
進抵抗となることがなるべく少くなるように配慮
される。 In addition, in order to control the movement of free water riding on the side edge 1a of the bottom outer plate, a free water stop plate 6 which also serves as a reinforcing material is appropriately provided, so that the free water flows rearward and becomes forward resistance. care will be taken to minimize this.
自由水制止板６には連通孔７が設けられて、小
波長の波の浸入によつても、たちまち船体の水線
面積を失つて、船体固有の横揺周期が変化できる
ようにしてあるが、船尾端部の自由水制止板６′
には、平水時の海水浸入を防ぐために連通孔を設
けない。 A communication hole 7 is provided in the free water stop plate 6 so that even when waves of a small wavelength enter the ship, the water line area of the ship is immediately lost and the roll period specific to the ship changes. , free water stop plate 6' at the stern end
No communicating holes are provided in the area to prevent seawater from entering during normal water conditions.
なお図は高速艇の左舷部のみを示しているが、
この船体はもちろん左右同形の形成され、図中の
符号８は上甲板、９は上甲板の船側線を示してい
る。 Although the diagram only shows the port side of the high-speed boat,
Of course, this hull is formed to have the same shape on both sides, and the reference numeral 8 in the figure indicates the upper deck, and 9 indicates the side line of the upper deck.
本発明の高速艇の船型は上述のごとく形成され
ているので、波長の短い波の中では、船底外板１
の左右側縁１ａ上に海水が積載されて、吃水線に
沿う船幅が吃水線における左右の船側面４，４間
の幅となつて小さくなり、船体の固有横揺周期が
長くなり、これにより同調横揺が防止される。 Since the hull shape of the high-speed boat of the present invention is formed as described above, in waves with short wavelengths, the bottom shell plate 1
As seawater is loaded on the left and right side edges 1a of the ship, the width of the ship along the water line becomes smaller as the width between the left and right ship sides 4 at the water line, and the natural rolling period of the ship becomes longer. This prevents synchronized rolling.
また、波長の長い波の中では、船体は波の斜面
に沿つて動き、船底外板側縁１ａ上に積載された
海水は、外部の海水と連通しなくなつて、吃水線
に沿う船幅が吃水線における左右の船体外板の側
縁１ａ，１ａ間の幅となつて大きくなり、再び短
い船体固有周期に戻るため、同調横揺が防止され
る。 In addition, in waves with long wavelengths, the hull moves along the slope of the wave, and the seawater loaded on the side edge 1a of the bottom outer plate loses communication with the outside seawater, and the ship's width along the water line becomes the width between the side edges 1a, 1a of the left and right hull shell plates at the water line, and becomes large, and returns to the short natural hull period again, thereby preventing synchronous rolling.
さらに、大角度横揺を余儀なくされるような非
常な荒天では、船側外方へ突出した船底外板側縁
１ａが、あたかも大きなビルジキールのように作
用し、横揺を減衰させることができる。 Furthermore, in extremely rough weather that forces the vessel to roll at a large angle, the side edge 1a of the bottom shell plate protruding outward from the ship's side acts like a large bilge keel and can dampen the roll.
次に、この船の推進性能としては、船底外板１
が従来の滑走艇と同様に形成されているので、そ
の性能低下をきたすことはない。 Next, as for the propulsion performance of this ship, the bottom shell plate 1
Since it is formed in the same way as a conventional personal watercraft, its performance will not deteriorate.
このようにして、本発明にれば、旅客用等の吃
水がほとんど変らない高速艇に適用して好適の船
型が得られるのである。 In this way, according to the present invention, it is possible to obtain a boat shape suitable for application to a high-speed boat for passenger use, etc., with almost no change in water intake.
以下、本発明の高速艇の有する効果を列挙すれ

少なくなる。(1) Regarding propulsion performance, it maintains the same performance as a conventional planing boat in calm water, and maintains the same conventional planing performance even in waves, and seawater is loaded on the side edge of the bottom outer plate at the rear of the hull. However, the water flow flowing backwards is small, so the additional resistance is small.
(2) 横揺性能については、波長の短い波浪中の場
合、船底外板側縁上に海水が入ることにより、

周期は再び短くなるため、長い波浪に同調する
ことがなくなり大角度の横揺が防止される。(2) Regarding rolling performance, in waves with short wavelengths, seawater enters the side edge of the bottom shell, causing
By lengthening the roll period of the ship, it is no longer synchronized with short waves, and it is possible to prevent rolls of large angles.In waves with long wavelengths, the ship's body rolls along the slope of the waves, causing the ship to move outside the bottom. The seawater on the side edge of the board no longer communicates with the outside of the ship, and the rolling period of the ship becomes short again, so it no longer synchronizes with long waves and rolls at a large angle are prevented.
