Lancerbye - yeah ... umm except, you'ld need several permits - the city permit
to remove a tree, the coastal commission would need to see your environmental impact study, you would need a construction permit
, a launch permit, and proof of insurance
. And make sure you pay your fees
for all of the above - oh, don't forget that while you are constructing your boat, you'll have to have a couple a dozen inspections by various local, state and federal "authorities". And, btw, all those people will come to visit using their SUV's and burning gas paid for by all of us (taxes).
Aren't we lucky to have such freedom??!!
Edit: Oh .. I almost forgot - On WHO'S property were you going to do this??
