Re: Sailboats and bridges

I found your post looking for something else, I have looked at the ICW and thought that I may need a contingency plan aboard when I decide to travel South from L.I. My vessel is about 60 ft in height and draws 7.5 ft.

Home Depot sells a bag called the “bagster” by (Waste Management) WM, it’s a soft garbage container it can be folded and stowed, I think they start at 50$

Encouragement:
Humans built the pyramids with rope, logs, chisels and an abacus. Rigging your vessel to safely pass under a bridge “sailboat limbo” is nor an abstract or dangerous concept.
Leverage is your friend, you will not need 1,000. Lbs, the further you get the load line away from the high point the easier it will be to heel the vessel over is it a fixed keel?
IF you have a static load line of 60m (this is standard climbing length) I would snake it around your keel (make sure their are no barnacles) , knot it above the toe rail for visual security, run the static line over the top of the mast “captured” and chafe free and down the other side. going over the mast from the keel will transfer the load to a downward force *mostly, and will reduce the diagonal/horizontal load on your rigging.
Then it’s a question of how far you need to get the vessel sideways, how much water it will take(how much load you will need). And maybe the most important part of the equation
...how far you can get the load out board? Spinnaker pole or maybe the boom? And you will need to be able to raise it the further over the vessel goes the higher the load will need to be as not to drag in the water.

Re: Sailboats and bridges

People have discussed the need for a strong halyard and the forces on the mast that might cause it to buckle (or not). No one has mentioned the lead on the halyard sheaves being foul. These bags will require using spinnaker halyards or sheaves that will have a fair lead off to the side of the boat, or chafe is likely to break the line. Even then the question arises as to whether the crane for the spinnaker halyard is up to handling the weight at such an angle. Spinnakers are not designed to pull down; they pull forwards.

The OP seems to really want to leave his masts in. Using water or weight bags does not seem to be the best way to duck the bridges. A better option might be a procedure that is routinely used to pull sailboats off shoals when they get stuck. All the OP needs is a heavy powerboat to accompany him on the trip. When they come to a bridge, they rig up a line to the masthead, just like with the waterbag, but they fasten it instead to a towline from the powerboat. The powerboat proceeds under the bridge and the sailboat turns 90º to the course under the bridge. The pull of the powerboat on the towline heels the sailboat over and pulls it along sideways under the bridge. This avoids all the fuss and worry of filling, lifting, emptying and stowing cumbersome bags. All the OP needs is a buddy with a powerboat.

Re: Sailboats and bridges

That seems riskier to me.

You are talking about pulling to heel and also drag sideways. That's a lot of load. After turning 90*, what immediately stops the boat so it doesn't run out of the channel or into the bridge columns?

Re: Sailboats and bridges

Just unstep the mast, simple.




But if you really wish to tilt the boat over be sure to do it with style. Send someone to walk up to the top so as to be able to gauge if you will clear the bridge,

they use 50 gallon plastic drums secured to the side deck at the Okeechobee railroad bridge

Re: Sailboats and bridges

The right tool for this job is probably the Bambi Bucket. I've got to assume they are cost prohibitive, but made for basically the task at hand. Helicopter water hauling and dumping.
  • Hold your desired volume of water
  • Made to be suspended from above while full
  • Built-in controlled dump valve
  • Built tough to last a lifetime of bridge clearing but fold up small for storage

The cheap option is a SuperSack + liner. The sack, while not waterproof takes the weight when suspended from above, the liner prevents the leaking so that your heel doesn't change while under the bridge

Your buddy with the powerboat needs to steer so you stay in the channel and don’t hit anything. What could go wrong?

Wow, that's the tallest tabernacle I've ever seen on a yacht!

And you can't even see the hinge...


Owwww!

Jim
If you hinge the mast forward instead of aft it won’t hit the helms person on the head when it comes down: no Owwww!

Interest place for the aluminum mast to have folded. With the center cockpit it looks like it may have avoided banging into passengers if they were off the aft deck.

That is an unfortunate and expensive mistake to have to replace. Why I wonder one would even try if there was not abundant clearance. Geez just find another route. There be plenty of water to float one's boat. Oh well, live and learn, or at least hope one lives to learn.
