Question #1 You can never really budget
as you can never really estimate when a "surprise" repair is going to come up. But you can estimate maintenance
changes depending on how much you run you engine
. For our Beneteau Oceanis
we changed oil
every 75 to 100 hrs. We sailed alot which saved us $$ Other maintenance
will depend on the year and how good the previous owner took care of it. Water
pumps and outboard repairs
seems to be a high maintenance. So if you can stock up in spare parts
its always good in the long run. I think the percentage is a good place to start but you really have to evaluate the condition and year of your boat.
alot. Dont procrastinate, if it needs fixing... fix it.
#3 Big expenses are engine
problems. Not sure where you are traveling but consider shipping/ weight. And if you have to have something shipped make sure to use the "Yacht in transit" or else you will pay lots of taxes!
#4 My husband and I are in the technology field and we had to work some of the time and WIFI
is good and sometimes not so good - at anchor. Most of time its better to go to land or when you are docking
at a marina, its all good. *I recommend getting a waterproof case to carry your laptop
Hope this helps! Fair winds and safe travels
