I am unable to create a ship hull with an accurate shape. Help would really be appreciated!

    I can make a good ship hull but it keep sinking. Wonder if you can fix it.

    @randomusername I'm having trouble with the front and it's geometry

    Actually, a video tutorial would be pretty cool

    @Feanor Is it possible to have a ship hull with a flat bottom (similar to modern warships) but have a bulge at the from. Like the Kiev Class carriers (Hint)

    Number one:
    The bow (Bottom section) So, just take a fuselage block (bottom part curved top part hard edges) that's around 5 wide and 2 high for a ship that has a beam and draft of 25 meters and 10 meters respectively.
    Reduce the width of the front end by 0.25 and add another fuselage block in front.
    Reduce the width of the new fuselage block by 0.5 and add another and reduce it by 0.75, then add a new block and reduce by 1, 1.25, 1.5, 1.75 and so on until it reaches 0.

    Number two:
    Now, heres the hard part. Take a fuselage block and flip it such that the width goes length wise along the ship (Call it block B) and put it on the rearmost fuselage block making up the bow. use a triangle calculator like this to find out how long block B should be.
    Example:
    if the block making up the bottom part is 1.5 long and reduces its width by 0.25, you'd input 1.5 to AB 90 degrees to angle A and 0.125 to side C (basically, see how much the width reduction is and halve it)

    Therefore, block B should be 1.505 in width (remember that it has to be facing lengthwise and that the height of the block should controlling its width and length be controlling how tall it is.) and 4.764 degrees away from 0, 90,180,270 or 360 degrees.

    Now for hull flaring:

    Take another block B (Let's call it block B1). Put it on a fuselage block directly behind the bow where the width reduction is 0 AKA it has to go straight and cannot get wider or narrower.

    Increase the width of this block B1 such that the width on top is slightly more than the width at the bottom and mess around with the rise and run to make it lean forward. Afterwards use the rise and run on on the block Bs on the bow to fit in with the Block B1.
    Here is an example of what the bow should look like at the end Anyone can use it.

    Now for the stern. just take instructions number one with a few minor adjustments.
    First off, you don't want it to go down to 0, but rather 1 or some value that's above 0.
    Secondly, reduce the height of the blocks halfway down the stern such that it reaches a a height of 0 at the very back.

    As for the blocks above the waterline, just follow what is being done below the waterline, except with no height reductions. But put a block at the very back and reduce give it a rounded bottom.
