Congratulations to the designers and builders. Considering the small size of the ship and its simplicity, the bow and the rear were designed to join in the central rectangular part in a very elegant dynamic manner. Knowing that the bow would be filly immersed the designer shaped the bulbous bow to maximize volume and minimize surface area, and incorporated the acceleration zones to always have positive pressure on the front hull till they meet the central rectangular part where the pressure reduces. A sharp bow is necessary when the bow operates at the surface of the water but with a totally immersed bow, the natural shape should imitate that of fish and birds where normally the front part of the cutwater is not "knife-edged" For the purpose and the intended role of that ship, that bow is excellent. I like the manner in which the joining line with the hull retreats down because of the presence of the wide hull which needs to stay above the water............but the designer did his best to imitate a submarine hull. Well done. Looking at the rear part using 2:39 as a reference, I like the manner in which the sharp chine of the rectangular hull joined the transom with what looks like a conical surface which is often used in air conditioning trunking. To support a shorter shaft and move the engine back as much as possible the central part was fitted and incorporated a canoe-like feature which provided the volume inside and also acted to keep the water streamlines entering the face of the propeller at almost 90 degrees ensuring that the relative entry angle is the same for the pitch used. Normally if the rear of the ship rises fast the water entry to the propeller is at an angle and the relative pitch on the horizontal blades is not the same and so the propeller would vibrate. The final run of the ship to decrease the rear angle as much as possible seem to have been well thought our not to rob the midship volume not to short to spoil the water entering the propeller and more drag due to the partial " vacuum" created as in the case of the upper surface of an aircraft wing where the medium will try and separate from the surface. Really there is no difference between aircraft and ship dynamics and might as well include land transport vehicles. Again congratulations to all the team who optimized most of the pertinent functions in this small ship.
Skip to 4:10 for the launch.
4:18 look on the bottom u can see a man almost killed by ship
4:16 that man almost got killed by a launching ship
well this ship launch with the man almost got killed by a launching ship

They launched without any warning. The horn was late. Too late.
Well launched 👏
Fantastisch!
Was het ook!

Tuyệt vời lắm 💯😍👍
