The two different types of shaft couplings that you might find on small inboard vessels are rigid couplings and flexible couplings. Rigid couplings are used when the alignment of the shafts is perfect, while flexible couplings are used when there is a requirement for some flexibility in the alignment of the shafts. References: 1. Information on rigid couplings can be found on the website of the Marine Education and Research Society. The specific information can be found under the heading "Shaft Couplings" (https://www.marinestudy.net/shaft-cou...) 2. Information about flexible couplings can be found on the website of R and D Marine. The specific information can be found under the heading "Flexible Shaft Couplings" (https://www.randdmarine.com/flexibles...)
