Kindly go back and read my earlier posts in your thread.
Would like to discuss this fact, and my comments are based on fixing a few Star hulls and direct conversation with a Starcraft design engineer.
There is no reason to drill a hole in a perfectly solid one-piece hull, yet Starcraft did it, and eventually corrected it on the newer models.
STRAKES, answer this question. How would water get into a strake if no drain hole to allow water in was present? Not from the topside. The deadrise allows gravity to flow water downhill to the keeline and out the bilge and/or drain plug.
A hole in the strake allows it to fill with water while the boat is in the water. That is a problem. Go check the aluminum gauge of the hull near your strakes versus the strake itself. The strake is much thicker, like cardboard versus a paper hull. When underway, the thinner hull flexes and water can be introduced thru the rivet channels that attach the strake.
KEELPLATE, older models have the drain hole, same concept. Starcraft admitted the flaw.
Keels in the 90's and early 2000's had an open end in the keel plate(strip). You launch the boat, the keelstrip fills with water, then pressure and flex creates leaks. Starcraft admitted the FLAW, and closed off the open aft end of the strip in current models.
Any hole in the bottom of your "bowl" is a breach.
There is a solution. Just think of closing off the breach in SOLID fashion from the outside. Also, if you have an opportunity to use Gluvit from the inside, concentrate on the rivet channels that attach the keel strip and strakes. Work fast so the Gluvit is the thinnest possible and heat the hull from underneath with a space heater, even on a warm day and let gravity help.
score!
