Welcome to CF and I hope we can be a useful sounding board in your transition to sail.
I am sure you are aware of the tradeoffs in bulk space when switching to sail, although many multi hulls have the room, you can pay the penalty of weight sensitivity if overloaded and planning offshore
trips to windward.
If you were considering a monohull
and wanted to maximize the aesthetics of a writing space, then finding an efficient pilot house motor sailor with good offshore
characteristics like my own StarGazer makes for a very liveable floating office with space for a reference library.
In offshore head
seas our trip averages are about 7.3 knots using very little fuel
with a comfortable motion.
It is great that you are cruising with the purpose of getting to know the destinations.
I truly believe using historical records and study greatly enhances your cruising destination
as we have done cruising the Pacific using the “Now and Then” impact of the World War II Pacific Campaign as a guide.
Good luck in your search.
