Aloha and welcome aboard!
I am so amazed at the technology for navigation
over the years. Also LED has made solar panels
a good investment. No need for those big alternators or generator
sets that so many folks thought were necessary. If you have a watermaker
then there's no need for a lot of tankage.
I did my cruising in the early 80s and a whole bunch has changed since then. I'm still a dinosaur about most the things and can do without a lot of it. GPS
is a really nice item though and I don't leave port without it.
