Check with the Dealer you purchased the boat from. They usually have a “BOAT KIT” that will have the essential equipment needed , an ore, fire extinguisher, sounding devise, a couple of PFDs and a signaling device. Make him through it in as part of the sale. He can afford it. You may do better price wise to try Walmart or Sports Paraphernalia in Gilford. The closest marine discount store, West Marine, is in Seabrook.
The State puts out a booklet known as The Boaters Guide of New Hampshire. It has every thing in it you will need to get started and it’s free. Most Marinas, Bait Shops and places that do registration have them. You can also go on line and read it. Go to

You can also down load it. It is in a PDF format. The first thing you should do is register for the safe boating class. Any one driving the boat is required to have a Safe Boater Education Certificate.
Have fun and boat safely on the BIG LAKE.
