Sailing yacht improvements -- 2

I am looking for one or more engineers to help me do a major upgrade to my Bali 4.5 from 2015. Among the things I want to achieve are: 1. Upgrade to all electronics and mechanics on board, including GPS, plotter, autopilot and watermaker. 2. Merge two cabins into one master cabin 3. Improvements and alternators improvements. 4. Solar panel installations 5. Lithium battery upgrades I am currently in Sicily. The person/persons should be ready to live and work on the boat for several months during this summer. The boat is fully vegan, so you will be expected to eat only vegan food on board during the working period. We have a very talented chef on board, so you will no doubt be happy with the food.
