AI Technical Summary
Existing boat flaps positioned at the stern cause instability, affect speed, and require complex adjustments to maintain balance, especially in varying sea conditions.
Positioning flaps on steps at the boat's stern, connected by a connection element, allows for balanced trim adjustments and improved water resistance, enhancing stability and speed.
The solution provides enhanced boat speed and stability by optimizing trim adjustments and reducing the need for complex weight distribution changes, ensuring better performance in diverse sea conditions.

Abstract
Description
[0001] A BOAT WHOSE SPEED IS INCREASED BY FLAPS PLACED IN DIFFERENT POSITIONS
[0002] Field of the Invention
[0003] The invention relates to a boat, the speed of which is increased by changing the place of use of the flaps used to extend the waterline at the point where the engine is located in the aft (stern) part of the boats.
[0004] State of the art
[0005] Today, new generation boats have steps on their bottoms. Steps are used as a method to increase the speed by reducing the wet area of the hull. Step openings are desired to be in contact with the air from the side parts of the hull by moving from the keel to the board. The air entering through the step ducts travels along the body, reducing the wet surface area in contact with water. The boat is cut off from the water by the buoyancy force created through the step channels through which the air enters.
[0006] In the state of the art, the submerged area of the boats can be large at the bow or at the aft (stern). If the bow of the boat is more submerged in water, it is called bow trimmed; if the stern part is submerged more, it is called stern trimmed boat. Whether a boat is trimmed fore or aft is determined by the waterline of the boat. Too much or too little trim level affects the area of the boat on the water. When the trim increases too much, the boat starts to bounce instead of sliding on the water. Trim settings are made by moving the engine up and down at the stern of the boat or by flaps attached to the stern. Flaps determine the waterline of the boat. Flaps called trim tabs determine whether the boat will lean to the right or left side, how far aft the boat will go, and how much it will touch the water. Flaps positioned all the way down help the boat get on a flatter plane and also allow it to glide at lower speeds. This generally improves sailing quality.
[0007] Flaps are always positioned at the stern of the boat. This brings with it some problems. Trying to adjust the trim from the stern of the boat prevents the boat from sinking or rising at the desired level. It may cause the boat to go very steeply and with its nose upturned while driving. It also negatively affects speed and driving stabilization. The working principle of flaps (trim tab) in the state of the art; flaps are two independently adjustable metal plates controlled by a panel at the helm. Flaps can help compensate for engine torque or uneven weight distribution. These cut the hull and propeller independently and enable lateral adjustments to prevent heeling. Flaps are mounted on both sides of the boat's transom. They are completely independent of each other; they are not dependent on each other.
[0008] When the focus is on adjusting the electric trim of the boat, two additional metal plates are needed to perform heavy lifting operations when it comes to tilting the engine in or out. In this case, both metal plates need to be bent inwards or outwards at approximately the same angle to suit the engine's power setting. This alleviates some of the work on the propeller and helps maximize performance. Once you start noticing the boat is heeling, without flaps there's not much you can do except move passengers and cargo or adjust your speed and course. It is possible to easily compensate for changes in sea conditions, weather conditions, etc. without the need to adjust the weight distribution or change the route.
[0009] As a result of the research on the subject, a utility model application numbered TR2011 / 05800 with a swimming pool that allows water skiing is found. The application is designed to have a composite material pool (1), a shallow area (1.1) and a deep area (1.2). The shallow area (1.1) is designed to prevent the speed of the water (2) from slowing down, and the deep area (1 .2) is designed to prevent the water skier from getting hurt when he / she falls. In order to create waves (8) on the shallow area, a speed boat (4) was placed for visual purposes, and behind the speed boat, a left flap (5), a middle flap (5.1) and a right flap were placed, which can make different types of waves. Thanks to flaps, waves in different shapes can be obtained.
[0010] As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.
[0011] Object of the Invention
[0012] The present invention aims to solve the abovementioned disadvantages by being inspired from the current conditions. The main object of the present invention is to increase the speed of the boat and ensure that the boat clings to the water by changing the positions of the flaps.
[0013] Another object of the present invention is to provide a controlled boat usage by eliminating the existing problems (such as adjustments in weight distribution, changing the route)
[0014] The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

[0027] Detailed Description of the Invention
[0028] In this detailed description, preferred embodiments of a boat whose speed is increased by flaps placed in different positions, which are the subject of the invention, are explained only for a better understanding of the subject. In Figure 1 , the boat (A) is connected to the engine (1) at the top at the boat stern (C) and the flaps (2) at the bottom at the boat stern (C).
[0029] In Figure 2, the steps (3) are positioned on the boat (A) and the flaps (2) are connected to these steps (3) with the connecting element (4).
[0030] The flaps (2), positioned at the back of the boat (A), are positioned on the steps (3) in new generation boats (A) using the connection element (4). In boats (A) that do not have a step (3), the points that will form a step (3) are determined, an interruption zone is created on the boat (A) and the flaps (2) are positioned in these areas using the connection element (4).
[0031] The fact that the flaps (2) form a water mark from the position of the steps (3) allows a more accurate and performant calculation of the trim distance from the bow (D) or the stern (C) of the boat. Steps (3) are positioned with the trim distance and flaps (2) are mounted at the position determined by the connection element (4).
[0032] Flaps (2) are positioned on the right and left sides of the boat (A), at least two in number. Under normal conditions, the right and left flaps (2) positioned at the boat stern (C) create balance according to whether the boat (A) leans to the right or left. The flaps (2) positioned on the step (3) with the connection element (4) allow the boat (A) to remain more stable against situations such as rocking of the boat.
[0033] The flaps (2) positioned on the steps (3) with the connection element (4) operate more efficiently. Creating a step (3) on the boat hull (B) compared to the boat stern (C) and connecting the flaps (2) to this step (3) increases the resistance of the boat (A) against water. It also allows friction to be increased or decreased at the desired level.
