Hi there and welcome, EricVentures! My fiance and I (mid 30s) likewise caught the sailing bug watching the Youtube people i.e. Delos, Uma earlier this year... did ASA
101 on Lake Lanier, GA during the summer and now in final stages of closing on a sweet boat
(knock on wood)!!! Years of experience be damned, the circumnavigation
commences on 1/1/2019! My timeline is aggressive (some would say crazy), so your plan seems perfectly reasonable to me. Do not delay
We have another thing in common: we also just returned from Tahiti
/ Moorea and had much the same reaction, vowing to return next year on our own vessel.
Best of luck in your journey, hopefully we will cross paths in some distant ocean!
