Aloha and welcome aboard!
Sometimes you can sign on to some really inexpensive classes
that help with navigation
and seamanship. One that comes to mind is the USCG Auxiliary courses. They don't cost much and give a lot of information. Its a place to start.
Even if you already sail a Laser sometimes its good to join a club or take a beginning sailing class so that you learn proper sail trim and all the safety
things that go with it. If you already race
your Laser against others in your area you are miles ahead of a basic sailing class so don't bother. Racing
teaches you sail trim and rules of the road for racing
. Remember that rules of the road for racing are not the same as rules of the road for sailing and powerboating so you need to learn both.
Hope this helps.
