During the late 1970s, the US Navy's David W Taylor Ship Development Center requested sea-based aircraft studies. Rockwell International Columbus Aircraft Division developed three C/STOL and three V/STOL sea-based aircraft configurations. One of these, a blended-catamaran C/STOL design, resembles the Lockheed "SeaStar" or "Sea Sitter" design that we have been discussing in other topics.
I found the attached Rockwell International Columbus Aircraft Division report presented to the DWTSDC on January 15, 1977 on the DTIC web site:

Perhaps someone with image editing skills can stitch together and edit the line drawings of the aircraft concepts and attach them?

Abstract:
This report presents an on-water head seas motion analysis of three C/STOL and
three V/STOL, sea based aircraft configurations. Heave, pitch, acceleration, and
slarmming/wetness conditions are determined. Different forward speed conditions
were studied. The effect of various configuration parameters (length, inertia,
c.g. location, water plane area, etc) on head seas motion parameters was established
Sea state conditions from one to seven were studied. Fundamental sea state relation
ships and their effect on sea basing of aircraft are presented. Recommendations
for subsequent model tank testing are indicated.
Roclkwell International Report NR717-113, "Sea Based Aircraft Habitability
Criteria" dated 15 October !976, provides a definition of the human limits
for sea based aircraft. habitability criteria including vertical, lateral
and roll limits for on-water operation are included. Motion sickness
limits are presented. No serious habitability limitations were uncovered
for the surface following sea based aircraft concept.
