Last week, there was a web posting about the main console in a Phil Evans boat. To complete the picture (almost), you need to see the sidetank controls that nestle between the helm and crew amidships.
In the photo (double click to see it larger), the stern is to the right of the photo. The purple line on the side tank is the kicker, and the black line is the mast ram.
It so happens that the spinnaker sheet in this boat is also black, but you can probably tell that this emerges around the ratchet block that you see here. The genoa sheet turret is pretty simple – and being hollowed out gives somewhere for the jibcar return shockcord to live, tucked out of harm’s way…. hopefully.

I am glad we don’t still use the metal genoa plinths – my crew’s blood was a regular sight and it makes a right mess of the main.
ha ha ha ha – you’re a hard skipper obviously !!
