Once the plug is finished to a very smooth and hi-gloss surface it is ready to be used to create the 
mold. Mold making involves spraying tooling gelcoat (paint) on the surface of the plug and then applying a fiberglass structure to the outside of the gelcoat. It’s like building a boat in reverse. Once the structure of the mold is in place the plug is released from the mold and voila! the mold is ready to be prepared and put into service making Sabreline hulls.
While I was in Fort Myers viewing the hull plug I also took some pictures of the deck plug which is following the 34 Express hull mold by a couple weeks.
The deck plug is a very complex piece of engineering and everything from styling details to the function of the cockpit seating has to be thoroughly thought through now. It can’t be changed once the mold is completed.
