9.5m HIGH SPEED SCOW Sport Fishing Boat 2x 250 hp Diesel Architecture& Design Andrei Rochian NEW DESIGN OF HIGH SPEED HULL Stabilised Transversally Propulsion is 2 Inboards diesel Direct Staight Shaft Optionally can be Hybrid Electric Elevated Command Deck Cabin with Double Bed and Kitchen Enclosed Sanitary Compartment Shower wc Fishing baits box aft LOA 9.5m B= 3m Max Speed +50 knots Hull Design and Performance Stability: The scow hull shape, characterized by a flat bottom and rounded bow, generally provides good stability, which is crucial for a fishing boat. Air Entrapment Tunnels: The tunnels running from bow to stern on either side of the hull can create an air cushion, reducing drag and potentially increasing speed. This design mimics some aspects of catamaran and trimaran hulls, which are known for their efficiency and stability. Trimaran Configuration: The trimaran-like configuration with the central hull and two side tunnels can provide additional stability and reduce the wetted surface area, which helps in reducing drag and improving fuel efficiency. Lift Strakes: The lift strakes on the central section of the hull help in lifting the hull out of the water at higher speeds, further reducing drag and improving efficiency. Propulsion System Power: With 2x 250 hp inboard diesel engines, you have a total of 500 hp, which is substantial for a 9.5-meter sport fishing boat. Speed and Fuel Consumption Estimated Speed: Given the efficient hull design and substantial power, the boat could achieve impressive speeds. Typically, a well-designed hull with 500 hp could reach speeds in the range of 50 knots, depending on the exact hull form and loading conditions. Fuel Consumption: Diesel engines are generally more fuel-efficient than gasoline engines. At cruising speeds (say, 20-25 knots), a rough estimate for fuel consumption could be in the range of 1.5 to 2.5 liters per nautical mile per engine. This means at optimal cruising speeds, your total fuel consumption might be around 3 to 5 liters per nautical mile. Diesel Inboard Engines (2x 250 hp): Cruising Speed: 20-25 knots Estimated Fuel Consumption: 3 to 5 liters per nautical mile (total) Gasoline Outboard Engines (2x 250 hp): #boat #boatdesign #design #nautisme #bateau #bateaux #barco #barche #BoatDesign #Motorboat #BoatBuilding #Watercraft #bootsbau #motorboat #sportfishing #design #yacht #barcapescuit #barcapescar #bateau #bateaux #barco #barche #pescuit #ambarcatiuni #sportboat #bateaupeche #bateaupechesportive #Design #SportYacht #pescadeportiva #BoatDesign #ambaractiuni #barcopesca #motorboot #sportfischen #design #yacht #anglerboot #fischereiboot #boot #boote #angelboot #anglerboot #bootsbau #fischen #wasserfahrzeuge #sportboot #angelboot #design #sportyacht #sportfischerei #bootdesign #wasserfahrzeuge

15m Go Fast Stepped Hull Sport Boat Outboards 3x300hp Architecture&Design Andrei Rochian Hull performance analysis and speed prediction - **LOA**: 15 m (Length overall) - **LWL**: 12.8 m (Length at waterline) - **Bmax**: 3.9 m (Maximum beam) - **BWL**: 2.8 m (Beam at waterline) - **Height of Hull**: 2.2 m - **Power**: 3 x 300 hp (900 hp total) - **Displacement/Weight estimated based on construction) 12,858 kilograms. **Planing Mode Prediction**: The total power available is 900 hp (3 x 300 hp). Power-to-weight ratio: 0.07 horsepower per kilogram. Froude number based on the estimated maximum speed, is approximately 3.44 **Estimated Speed Calculation**: **Maximum Speed in Planing Mode 75 knots. This is the estimated top speed the boat could achieve when planing, utilizing the full power of the three 300 hp engines (900 hp total). High-Speed Turning Stability: Plumb Bow (Longer Waterline): More Stability: The longer waterline provided by the plumb bow contributes to significantly better stability during high-speed turns. The boat has more surface area in contact with the water, meaning it is less likely to skid or slide sideways. Safer Handling in Rough Seas: The boat’s more predictable handling in sharp turns, especially in rough conditions, makes it ideal for offshore and high-speed operations where safety and control are critical. Raked Bow (Shorter Waterline): More Agility but Less Stability: While the shorter waterline of the raked bow allows for faster, tighter turns, it comes at the cost of stability. The bow tends to rise during turns, reducing the hull’s contact with the water, making the boat more prone to skidding or loss of control at very high speeds. Riskier in Aggressive Turns: For boats that will be operated aggressively or in rough waters, the lack of lateral stability in a raked bow could lead to less safe handling, particularly in offshore conditions. #gofast #bateaugofast #gofastsportboat #gofastboat #boatdesign #yachtdesign #sportboatdesign #designbateaux #bateaux #bateausport #conceptionbateaux #SportBoat #HighSpeed #HighSpeed #NavalArchitecture #NauticalDesign #Hydrodynamics #SpeedBoat #SportBoats #Sportbåt #Sportboot #BoatDesign #GoFast #BateauGoFast #GoFastSportBoat #GoFastBoat #BoatDesign #YachtDesign #SportBoatDesign #DesignBateaux #Bateaux #BateauSport #ConceptionBateaux #SportBoat #HighSpeed #NavalArchitecture #NauticalDesign #Hydrodynamics #SpeedBoat #SportBoats #Sportbåt #Sportboot #BootDesign #SchnellBoot #BarcoRapido #BateauxRapides #BarcoRápido #HurtigBåd #KiirePaadi #Átralaiva #Gåsnabbt #Murmalajr #προχώραΓρήγορα #γρήγοροΠλοίο #σχέδιοΣκάφους #venesuunnittelu #vene #sportvene #urheiluvene #WaterSports #알루미늄보트 #알루미늄스포츠보트 #알루미늄스포츠낚시보트 #アルミボート #アルミスポーツボート #アルミスポーツ釣りボート #鋁船 #鋁運動船 #鋁運動釣船#铝船 #铝运动船 #铝运动钓鱼船#ambarcatiuni #BoatDesign #barci #iahturi #barcos #Wassersportliebe #SportlicheBoote

Powercat/ Power Cataraman: The power catamaran boat design features twin hulls connected by a bridge deck in various sizes for different activities. Power catamarans come equipped with large engines that produce high speeds with reinforced hulls to handle the weight and power of these engines. Catamarans are also more likely to stay upright in a heavy gust even though they are more lightweight compared to sailboats. Also faster than other sailing vessels, catamarans, have less drag on the hull because of the smaller surface area in contact with water. - - - - - - #yachtcharter #howtobookacharter #bvi #greece #bahamas #usvi #wherecanwetakeyou #comesailsaway #luxuryyacht #vacation #songsinthesailsyachtcharters #athensga #atlantaga #alpharettaga #oconee #powercat #horizonyachts

Setting up a sea pool from a yacht in record time involves advanced engineering and specialized technology. Have you tried it yet? Here are some key technologies and methods used: - Inflatable Structures: Sea pools use inflatable technology, allowing for rapid deployment with durable, puncture-resistant materials that can be quickly inflated and secured to the yacht. - Modular Design: Some sea pools have modular components that are lightweight and easy to handle, enabling crew members to quickly assemble the pool on-site and deploy it into the water. - Hydraulic Systems: For larger or complex pools, hydraulic systems assist in the deployment and retrieval processes, ensuring smooth lowering into the water and stability during use. - Advanced Anchoring Mechanisms: Sea pools feature advanced anchoring mechanisms like suction anchors or tension lines, securing the pool in place and preventing drifting in the water. - Automated Deployment Systems: High-end yachts use automated systems integrated with onboard technology to deploy the sea pool at the touch of a button, quickly providing a safe and enjoyable swimming environment in open water. By combining these technologies, modern yachts can efficiently set up sea pools, enhancing the swimming experience at sea. #innovation #technology #yacht via @motoryachtloon #superyacht
