Funny I did not think the advise was negative...just realistic.
Never sailed the boat
Buys it after survey gets on it with no ocean experience...
I think you meant, "Buys it sight unseen, with no survey."
Sometimes it's hard to find the right balance of skepticism and encouragement, but I think Chef's remark nails it: what would I say if my son came to me with this plan?
The kicker for me was the 100 miles in 10 hours. Many unlikely things are possible with thorough planning; many simple things are dangerous with no planning.
Siz, my advice would be to pay for a survey, then find an experienced crew to go with you.
