Benchytitanic (bridge -ironing - stringing - retraction) inspired by the titanic

inspired by the titanic,
in addition to the tests of good ventilation and overang of the basic model, this remix tests a larger bridge and tests retraction and stringing. The ship's exhausts are staggered to account for tilt.
even the changes are evaluated

the upper base can serve as a test for ironing

the hull contains all the other parameters of the original benchy such as holes, width distance etc etc..
