First, you will want to pinpoint all of the individual leaks. To do this, fill the boat with water, then check the underside for leak locations. You may want to use some food coloring to be better able to identify the individual leaks.
Mark each leak on the underside of the boat so you can easily locate them later when patching/repairing.
Now you have several choices for repairing the leaks:
1. For cracks in the aluminum you can get them welded. Relatively permanent fix. You will have to find a shop that is experienced in welding aluminum. You can also try JBWeld or Pure silicon caulk which will work on some cracks, but will not be permanent.
2. For leaking rivets you can use JBWeld, Pure Silicon caulk, or replace the rivets. The JBWeld will be semi-permanent, but you will most likely have to replace it eventually. Pure silicon caulk will be temporary, but may last quite a while if allowed to cure before using. Replacing rivets can be permanent, but I expect the cost will be much higher unless you can do the job yourself.
The "quick" fixes (JBWeld, Silicon caulk) are for relatively small leaks. Larger leaks may require welding. The JBWeld can be a pain if it needs to be re-applied as you really need to remove the earlier application before applying a new one. The silicon caulk will probably not last as long, but is much easier to remove prior to re-applying.
DO NOT FIBERGLASS THE BOAT!!! You will most likely end up with a very heavy boat with lousy handling and more problems associated with the fiberglass than you have now!
Hope this has helped.
Good luck and good fishin'
