To make Family ship based on fish. It is one of the oldest concepts in the world to replicate nature so i’ve chosen Killer Whele :

First try:Second try of HULL: Project : Killer WhaleDesigner : Svetlozar NeykovCreated by : Svetlozar NeykovComment : Sinmania@abv.bgFilename : D:\EMSHIP\freeship\killer whale10.fbm Design length : 7.000 [m]Length over all : 9.667 [m]Design beam : 3.500 [m]Beam over all : 4.675 [m]Design draft : 0.500 [m]Midship location : 3.500 [m]Water density : 1.025 [t/m3]Appendage coefficient : 1.0000

Calculations (First Try):

Volume properties: Displaced volume : 0.848 [m3] Displacement : 0.870 [tonnes] Total length of submerged body : 6.731 [m] Total beam of submerged body : 1.276 [m] Block coefficient : 0.1976 Prismatic coefficient : 0.0000 Vert. prismatic coefficient : 0.3176 Wetted surface area : 6.923 [m2] Longitudinal center of buoyancy : 8.039 [m] Longitudinal center of buoyancy : 75.127 [%] Vertical center of buoyancy : 0.396 [m]Midship properties: Midship section area : 0.000 [m2] Midship coefficient : 0.0000

Calculations (First Try):

Waterplane properties: Length on waterline : 6.042 [m] Beam on waterline : 1.276 [m] Waterplane area : 5.342 [m2] Waterplane coefficient : 0.6220 Waterplane center of floatation : 8.412 [m] Entrance angle : 11.864 [degr.] Transverse moment of inertia : 0.504 [m4] Longitudinal moment of inertia : 10.723 [m4]Initial stability: Transverse metacentric height : 0.990 [m] Longitudinal metacentric height : 13.034 [m]Lateral plane: Lateral area : 1.458 [m2] Longitudinal center of effort : 7.653 [m] Vertical center of effort : 0.355 [m]

Calculations (First Try):

The following layer properties are calculated for both sides of the ship:| Layer | Area | Thickness | Weight | COG X | COG Y | COG Z || | [m2] | | [tonnes] | [m] | [m] | [m] ||-------------------------|--------|-----------|----------|---------|---------|---------|| Layer 0 | 49.612 | 3.000 | 0.116 | 8.141 | 0.000 | 1.264 || Semi ellipse rudder 65- | 0.819 | 4.000 | 0.003 | 5.508 | 0.000 | 0.283 ||-------------------------|--------|-----------|----------|---------|---------|---------| Total 50.432 0.119 8.069 0.000 1.237   Sectional areas:

Calculations (First Try):

NOTE 1: Draft (and all other vertical heights) is measured above the lowest point of the hull! (Z= -0.169)NOTE 2: All calculated coefficients based on actual dimensions of submerged body.

SECOND TRY:TOO HEAVY

FINAL:

 PRODUCTION:

Materials: Composite FibreglassThickness: 3-5mmDensity: 2.6 g/cm3 Weight: depends around 200 kg depends of the type construction.Stability: WingsStrength: ScantlingConstruction: Two main points. First Propeler is mechanical-elastic wing which moves verticaly. Rudder are two upper is mechanical-elastic, down is type of NASA profile.ENGINE: SHOULD BE EXAMINED MORE – IT MUST DO A LOT OF JOB FOR MOVING THE WINGS AND RUDDER. MAYBE ENGINE OF CAR – VOLVO. PLACEMENT IN THE BACK OF THE HULL.

FINAL:

It can be constructed because – SEE MOVIE ABOUT DOPLHIN BOAT!;) Transport: Can be attached 4wheels and can be pulled from two ropes attached to the front of hull and back of the car.Conclusion:Heavy, Nice hull design, can be used on roads also.
