I'm on the north side of Lake Winnipesaukee in Moultonborough. It makes a difference where you are on the lake as to what is convenient enough for you to be a good suggestion with 15 guys drinking. Keep in mind police at the Lake stop a ton of cars as their only entertainment. Wolfboro on the lake is 45 min from us by car and Weirs Beach 30 minutes in a different direction, and Alton Bay another 15 minutes past each of those, (without summer weekend traffic). So stay close to your 'home' area. Each town on the Lake has it's own character. Wolfboro everything is quaint, taverns overlook the water, and the area right at the docks has a 2nd and 3rd floor bar with outside seating, an inside bar with tvs, and a large game room. There are other walking distance taverns - mostly upscale. Weirs Beach is the honky tonk. NASWA at Weirs Beach is a perfect beach bar that has areas under a tent, you can swim right there, they have tvs under the tents, have weekend bands, bikini contests if any of your buddies look good in a bikini. Partying on your own boats is great but if that isn't working out you can take the Mount Washington for a tour of the lake and get on/off at any of the major towns. They serve food and I think drinks (but check) and I'm sure it is at least 2-3 hours on the water. Seating is inside and outside if the weather isn't cooperating, and the boat is very big. Most bad weather is temporary so my bet is you gut it out. In good weather your rental 'fleet' can raft at one of the major sand bars on the lake, Baum's Bay, with 100-200 other boats partying. Buy a couple cheap water type footballs to bring on the boat and throw near pretty girls to introduce yourselves. Patrick's Pub in Gilford is a lively place good reasonable food, and inside, but not at the water. Meredith has a good bar on the water next to the docks but mostly outside so not so good in the rain. If you are on the northeast side of the lake and it isn't raining, the outside seating at Castle in the Clouds overlooking the entire lake is a WOW. Like being in the alps. It has a bar but tourists, and is just an hour or 2 destination in the daytime, not a place to hang out and party. There is free access so if you take the road up that charges a fee, go back down and there is a free access road about a mile away near the intersection of rte 109. Most other places are good places to drink but talent is hit or miss, mostly miss. All else fails, come and visit, we're 7 ft from the water, good views, canoes, a lot of deck space and maybe enough booze for 15 guys for 3-4 hours.
