If your plan is to leave in 2010 then you may have left your run a little late.
Looking at 80-100 boats is not unusual, and they each take 2-6 hours. The advantage in this is that by the time you get to boat #60 you know the brokers pretty well.
a good boat for $70k is for 4 people going to be a challenging exercise, particularly living away from the water
. Don't forget that at least an additional 50% (or $35k for a $70k boat) needs to be budgeted for repairs
, upgrades and improvements.
You really need more money
or more time, preferably both.
