I know they are outdated, but I still have a nice one & wondered if others also carry them & where do you keep them aboard. We have all gotten into the fast fix of the electronic world, but we shouldn't lose the knowledge of a mechanical fix.

sextant storage

Re: sextant storage
Agreed John. I have 5, dating from 1840 to 1990. I have revamped the calculation process so that it can be done on a computer in Microsoft Excel format, or by a simple function calculator. Obviously the former is quick ( about 2 minutes ) and the latter slow ( about 10 minutes ).
I still use celestial navigation to give me gross error checks in the middle of the ocean when positioning offshore structures such as rigs and barges by DGPS. I usually get better than 0.5 mile in the fix.
But where to keep the sextant aboard the yacht?? None of the boxes except for the plastic Davis one will fit in the CD30 shelf.I thought of making a smaller box which just fits the instrument and being thinner might fit into the shelf.

Re: sextant storage
Like Murray says, the Davis box is the only one that fits behind the settee. I just stuff my Hezzanith in the Davis box when I'm taking it with me. Its own box is way too big.john wrote: I know they are outdated, but I still have a nice one & wondered if others also carry them & where do you keep them aboard.

Re: sextant storage
I have a Frieberger that is stored in its original wooden case and I have 4 wooden (1/2" teak) * L * chocks that are mounted to the ash ceilings in the v-berth which retain the case in a specific position. I used two criscrossing 1" webbing straps with plastic quick release buckles to secure the case within the chocks. The case is located high up on the ceiling sides just below the deck, it does not get in the way of using the v-berth.john wrote: I know they are outdated, but I still have a nice one & wondered if others also carry them & where do you keep them aboard.

my astra in its wooden box gets wedged on the top open shelf on the starboard side, it has yet to fall from there but i suppose a strap could easily be set up to hold it even tighter - i only have it aboard when i am going offshore
