I own a 89 Worlds Hobie 18. The anchor plates are at the shrouds, and the inside and outside of the front beam. The best thing to do is to find used anchor plates (on the web)and install them as soon as possible. I plan to add ports aft of the rear beam and four anchor plates to the rear beam next winter as I have found some magnum wings to install for crusing.

I also helped my crew fix the seam on his Hobie 16, it had come unglued in some areas. Here is how we did it. Flip the boat upside down, grind the silcone off the edge of the seam. (Hold a piece of cardboard against the hull so if you arn't careful the cardboard takes the grind marks not the hull). Vaccume the seam out. Tape the gelcoat on the "deck" letting it hang down. Mix up some thickened epoxy, pour it into the seam while someone holds a vaccume against the drain plugs. After enough epoxy gets sucked into the seam, turn off the vaccume and clamp the seam shut with spring clamps. After a day cure remove the spring clamps clean up the hull & deck and check the hull for any leaks. Repeat if necessary.

I did about the same thing to the front seam of my comptip, it worked great.
