I am adding a ski pylon to my boat and want to know if it is safe to screw it into the floor of my fiberglass boat and if it will withstand the weight of pulling people.

You would normally have to use a "Backing Plate" of some kind. Determine where the pole will be placed and note it's footprint. Under the deck mount a plywood plate. It should be at least 3/4 inch thick and cover a much larger area than the footprint of the pole. Ideally it should be fiberglassed in to keep it away from any water. Drill the holes for the footprint. When mounting the pole, use a bedding compound like Sikaflex or 5200 for a waterproof seal. BOLT the pole down; don't use screws. On the underside use oversized washers between the nuts and backing plates. I recommend a Nylox style of nut so that you don't need to worry about them loosening off later. Having said all of this, remember that a ski pylon exerts tremendous loads on a deck. You should have it look at by someone who understands what's going on to at least recommend what to do in your specific case.

Chances are that it will be no problem. Most boats have flat floor with a space beneath to the hull. Any after market ski pylon should have struts that attach back to the transom to transfer the pulling forces to the transom. The pylon is simply there to get the pulling force centered and higher than a stern pull.

You would have to consult with a dealer that knows your boat. You would have to locate the framing under the inner floor and place the screws in the framing. No if you just screw into the inner floor the screw will pull out and may kill someone. i know of a person that got permant brain damage from one of those things pulling out of the boat and it hit him between the eyes while he was skiing behind the boat. Use caution when you are doing this.

Larry has the details right.....a big beefy backing plate with the pylon THROUGH BOLTED NOT NOT NOT NOT NOT SCREWED to the backing plate...if you don't know 100% how to do this get a pro to do it for you...probably not more than two hours and $50.00 bucks of materials......otherwise someone will get badly hurt 100% for certain.
