A tip for checking behind the desired drill area, get one of those high-strength neodymium magnets and tape it to the surface. Then use something magnetic like a regular steel screw or washer (as stainless isn't magnetic) and see where the magnet holds it. There can be all sorts of things behind the location you might want, bulkheads, tanks, wiring, etc. That and some surfaces are thicker than you might expect due to having a core (like an engine hatch). Not that it applies to this particular question.

Also consider a hanger of any sort my be employed to hold more weight that you originally planned. This is why some of the fender hangers on the market do not use a cleat-shaped mount. They don't want someone doing something stupid like tying a line to it and having the load rip out a whole section of fiberglass. Any time you're putting something on the outside that might incur added pulling stress you usually have to add a backing plate. This plate helps distribute the stresses away from just the two bolts alone.

Some locations are easier to install than others, but some locations will never be suitable due to there being no way to set up a secure method to distribute the stresses. That's why I use the suction cup mount on my 348. The area best suited to hang a fender is actually just a "cap" panel of sorts. That top part of the aft gunwale just covers the engine room vents below. It's not a part of the main hull. Nor does it have a way to secure a cleat to it in a way that could hold any sort of load from a line.
