Quoted:
I'm amazed at all the people with expensive boats that did not take them out of the water. Like what did they think was gonna happen?
leaving large boats IN the water is usually safer than pulling them.
there are generally four options (five if you include sailing the boat completely out of the path of the hurricane)...
1. hauling the boat and putting it up on blocks at the marina.
for most people this is "option A". the danger is that the boat "floats" off the blocks. even if your boat doesn't float off the blocks, if someone else's does your boat is a pawn in a big game of bumper boats. some folks will leave the plugs out with the boat up on blocks. the boat gradually fills with water as the sea comes up. this delays when the boat floats off the blocks. but again, EVERYONE has to do this for it to work out. finally, a 15' storm surge accompanies by 15' waves can push ANY boat off of it's blocks.
2. hauling the boat and putting it up on blocks somewhere else.
only an option for boats up to about 30-ish feet and with less than 8 foot beam. you can't put a 40' fishing yacht on a trailer –– weight, width, height, etc are all prohibitive.
3. staying in your slip ('dock' to most of you) and lengthening the spring lines.
this is one of the most difficult and unpredictable methods, and requires A LOT of neighbor coordination. foremost there are two kinds of docks –– fixed and floating. with a fixed dock, the dock stays at one height and the boat moves up and down in relation according to the tide and storm surge. with a floating dock, everything moves in unison. ideally. with either dock type you will need lengthy spring lines and the hope that your fellow boaters have tied up correctly so as to avoid bumper boats. with a fixed dock the lines have to be long enough to prevent "drowning" the boat, but not long enough to allow the boat to bash the dock structure during high winds/seas. with a floating dock the biggest danger is the dock breaking away from the pole pilings, and/or a big enough wave "shish-ka-bobing" the boat on a piling.
4. anchoring the boat on an inland waterway.
this is actually one of the best options. take the boat up into shallow water, a few feet deeper than the draft, and 'storm anchor' it using 4 anchors. put 3 off the bow to the windward side, splayed out at about 30 degrees each; and 1 aft to the leeward side. use tons of scope, 7:1 to 10:1 at least. see picture below. now back the boat down and dig the windward anchors in hard. leave some slop at the leeward end. it's impossible to get big waves in shallow water, so you will not see the 15' ocean rollers. the anchors have to hold against the wind. using the "big sea" theory, you should not have to deal with debris strikes (other boats, broken off docks, timber, etc). some elect to stay onboard for the storm; others set it up, kiss it goodnight, and dinghy away to shore.
