Raasay came with a very substantial base for a radar pole bolted through the afterdeck - the mount extended below the deck and was through bolted to the gas locker bulkhead.
It seemed a shame to waste it, so when I decided to fit a radar I wanted to use the mount.
I thought I'd make my own pole, and also thought I'd try making the mount tiltable. The outcome is robust, but, I'm afraid, a bit ugly. The first version was just the inverted 'y', plus the tilting bits - the uprights are ash. Unfortunately this was not quite stiff enough so I put a single iroko stiffener up the back of it. The result works, more or less.
The tilting mechanism is based on a big bottle screw from a junk box. It's a bit stiff and slow. That may be OK, as I mainly had long close reaches in mind rather than a beat.
I'll see how it goes. Mk II will probably benefit from the experiment ...
