I think the wing sail idea was done 25 years ago. Walker? Never took off commercially.
I always liked the unstayed (carbon fibre) masts of the Freedom yachts from the 1970's.
But that could be because they also looked a bit Piratey
For anything commercial
(in that size / price
bracket) will need all
mod cons. and the power to run them. and to look bling enough to look "good"
in a Marina (where it will be living most of the time).
Folks like being ecoists better when sipping cold drinks in a Jacuzzi........
But, in the spirit of these things
I would build a ginourmous Trimaran
- they look sexier than a Cat
) with a totally
(big cost savings on build time and fitting out). Something 65 foot+ with a f#ck off sized bow sprit
Maybe unstayed mast(s) ala Freedom.
The hulls would conceal storage
, and maybe some pop up pods for things like Sink, Fridge. and toilet
Could even include an underdeck built in Jacuzzi
Obviously will need sleeping / dining accomadation - for that I would use canvas
to create modular / flexible accomadation plans, including a wheelhouse. Think beyond backpacker tents to a Yurt! and if BMW etc can produce fabric
roofs that survive 150 Mph in all weathers, then no reason why cannot have similar on board a yacht.
Obviously setting up "camp" for the night may be a PITA - but on something that size having crew (or a Skipper) would not be unusual (and normal for Charter). Plus depending on design, some of the "tents" could be left erected on passage
. If you have struggled to acheive an erection it's always a shame to put it away........
