3. Conception Selection 22/09/2011 2 A simple U-Shape hull line is selected. Considering the arrangement of engine, fuel tank, personnel and steering, a length of 3-5m, width between 1-2m is roughly selected.
4. Hull Line Design 22/09/2011 2 Put the estimated main dimension to MAXSURF and drag a rational hull as the design. Finally get the main dimension L=4.44m B=1.25m D=0.73m at bow =0.48m at stern
6. General Arrangement Design 22/09/2011 2 Based on the rough calculation through MAXSURF, the crew seats are placed behind the midship in the stern direction. Luggage place is placed behind the seats Behind the luggage place, the fuel tank is arranged The engine is put aft the ship. Other small items are placed fore ship to balance the weight
7. Conception Selection 22/09/2011 2 Small integrated propulsion system as first choice. Water-jet as second choice Finally chose integrated propulsion system because it is lighter
8. Conception Selection 22/09/2011 2 Glass top are added to prevent the crew from getting too much sun and protect them from rain
10. Material Selection and Weight Estimation 22/09/2011 2 To reduce the hull weight, composite material FRP is selected. Assume plate thickness is 9 mm, the hull weight is roughly 71kg. Considering the personnel, fuel, luggage weight and check the rough calculated displacement, there is a balance.
11. Stability Evaluation 22/09/2011 2 Since there is a balance between displacement and weight and majority weights are located at lower place, there should not be a big problem for the stability. However, the dynamic stability should be paid attention to if the boat is going planing.
12. Structural Design 22/09/2011 2 Some transverse frames are designed to strengthen the ship. The ship is divided into 10 stations. They are placed in station 1,3,5,7,9
13. Construction Mode 22/09/2011 2 A male mode is made Resins and polyester can be sprayed to the hull Transverse frames are connected to the hull by stitch and glue
