I believe it to be a wise choice to do this first before
diving into
ownership. Like the other post, you will probably have a hars time finding someone willing to do it.
Do you have any boat related skills with
references?
Nobody wants to get booted from their marina and they could with you
living aboard. If you come and go early and late that may help. I find
marinas give sneakaboards a break if they are doing a
refit, a solid reason to need to be there a lo and don't do it for more than a couple of months.
Asking someone to move onto their boat for free in exchange for sitting is not a good deal to the owner. You could break stuff, that costs sometimes 1000% or more than a like version in a home or car.
My
advice is to do a craigslist ad in the
boats section. Perhaps even reaponding to some that are
for sale that may be hurting for cash.
Lastly, the air bnb suggestion is probably your best bet.
In FL I think its a lot more cost effective to rent a place that
liveaboard a boat. Slip rates can be be over $20/ft, by a 30 boat thats $600/mo without including
insurance,
repairs, haulout etc. It could be $1200/mo easy on avg. Especially since you plan on not going anywhere is juat seems wasteful.
Why not go rent something on land (or downsize from where ya are) and buy a small something you can keep on a
trailer? That is small and low cost to maintain (a
kayak to a boston whaler) that gets you on the
water to explore or
fish or whatever it is that ia drawing you to wanting to
liveaboard a powerboa in a marina.
