Theoretically you could push the boat, I don't see why thats crossed out. o:
It flips, I've done it 5 times in a row... I think it's impossible, will be trying it again.
Ask an admin for a teleport.
I can't ask an admin everytime I wish to leave my house

- But I don't see no ways of putting the boat there, and taking it easily.
Ehm, get it onboard of a dumper someway.
Will be trying it right now

You can buy a Buffalo or a Bullet. I've owned that house and i succeded to put a Buffalo/Bullet there.
Yeah, but I wanted to put a boat :<.
