After a 2 year absence I've decided to return to drawing ships here on SB. One such ship that's been on my mind lately is an obscure design I saw in a book many years ago but have been able to find. From what I recall, the ship was an odd and failed attempt to reduce seasickness for passengers by having a cylindrical structure containing the passenger cabins and amenities that would counter rotate along the roll axis.
I haven't been able to locate any references or images online and hope someone else may have better luck tracking down the odd vessel.
I've included a quick cross section drawing of the ship.
I did manage to find several drawings of B.T. Babbitt's rotary engine vessel which is another ship I plan on drawing.
