    Re: C.Plath Yachtsman Sextant

    Please see attached photo of the Plath Yachtsman sextant that Greg Rudzinski and I tested at Port Canaveral, Florida, earlier this week.

    In Bill Morris's excellent blog post (https://sextantbook.com/category/c-plath-sextants/)  as well as in other photos I've seen, the Plath Yachtsman is blue.

    Posts about C Plath Sextants written by engineernz ... The frame is closed off at the back by a back plate, which is attached to the frame by three screws and a leg.

    Mine is orange.  Any idea why?  My guess is that it was painted orange for use as emergency gear, but that's just a guess. 

    Also, maybe Bill Morris can tell me whether the lens is glass or plastic.  The coating has blistered on my scope's lens.  I don't want to use a solvent to remove the coating if the lens is plastic.  Any advice?

    This is an elegant beast. I’d be interested in seeing anyone’s comments on it in use in comparison to the 1970s Zeiss Freiberger 7/8 size Yacht Sextant. I own one of the latter (bought it c.1975) and used it for years until I acquired a Tamaya in 1987. The blog doesn’t seem to identify a design and production date bracket - anyone know?

    A few days ago Jackson McDonald and I were able to put a C.Plath Yachtsman to the test by observing the upper limb of the Moon from a pier near Port Canaveral. This version of Plath sextant is uniquely simple and compact with little compromising of precision. Bill Morris has a fantastic blog post on this model for anyone who has one of these or interested in getting one.
