Re: getting a Tartan 34C ready for offshore trip

Solar panels: I assume that you have calculated your input requirement and have determined that 2 X 120 Watt will do the job. You will have your fridge running all the time, as well as your instruments (especially since you plan to have an autopilot).... Will you be listening to music much of the time and will that be on the ship's battery system, too? While 240 Watt may seem like a lot, if the panels are rated 17V, feeding into your 12V system, you will get only 12/17 or 70% of the rated input. Reduce that for "manufacturers optismism", and actual sun power hitting it, and you quickly reduce the juice... especially if you end up on a starboard tack going east, when the sun angle may not be optimal.

I would also be more comfortable with more chain than you have so far.

Good luck with your preparations and the trip itself!
