Vivo,
A few things you'll need to know about boats:
A boat is a hole in the water in which one pours money.
BOAT= Bust Out Another Thousand
As for your local boat builder, find a model you like that's a few years old, look around it for stress cracks, look around the stern as that's the part that takes most of the beating. a couple of big outboards that weigh in excess of 500 lbs each twisting and turning pumping and pulling on the rear end will tell if the quality is there or not. Also talk to the manufacturer, see if the glass work is hand laid or done with a chopper gun, hand is always better, more even and less weight in the hull. Some of the biggest manufacturers use chopper guns (searay) it doesn't mean it's bad but just not as high quality. There are too many methods to get into but there is a forum I highly recommend you look into.
Let me know if you can get thehulltruth.com where you are, you'll find a wealth of information, far too much to view in less then 1 year IMO. You'll find forums and sub forums on everything you need to know. Electronics, hull design, flotation, eng's fuel etc.
You'll find me in dockside chat mostly, so welcome aboard. I'll gt back to you later on, got to run now.
