After a few days of unfavourable weather conditions ( rain, wind, snow, cold ), it is now ok again to work in the shed. The footwell underside has a layer of glass, and the footwell sides have their first coat of epoxy. The box for the electrics has a couple of coats of epoxy inside and outside.
I made and installed a channel for the cable from the battery to the top of bulkhead 2. From there, the cable(s) will be fixed underneath the cleat for the forward deck – two pieces of thin flexible conduit will do the job.
