In addition to renting out two-seat or four-seat pedal boats, that will be an excellent location to rent out stand-up paddle boards and kayaks/canoes as well.
Four different pedal/paddle vessels: pedal boats, sups, kayaks, and canoes seem like a good use for that Lake Winnipesaukee location out front the Weirs Beach sandy beach, 250-yard long swim, rope line, lake location between the Laconia town docks and the busy Weirs channel.
The Town of Waterville Valley Recreation Dept runs a June thru October, paddle/pedal vessel rental business with a total of 24-vessels with four 4-seat pedal boats, sups, kayaks, and canoes for use on 7-acre Corcoran's Pond which is a dammed up, 10' deep, mucky resort pond with a well groomed sandy town beach, that is open to everyone for no charge. It is a very good place to go swimming. It costs about $15-20/hour to rent a vessel and includes a paddle and a pfd. Just like Weirs Beach it always gets posted with those orange cyanobacteria DES warning signs in late July or early August but that doesn't really interfere with small boat users who are on the water, but not in the water. Except for the pedal boats, all their different rental fleet sups, kayaks and canoes look like something purchased at Walmart for $200-450.
Ekal Activity Center in Meredith ....

Looking at a Weirs Beach pedal/paddle rental biz, potential customers will see the boats from either the Weirs Beach sandy beach as a beach goer, or from the Lakeside Ave, Weirs boardwalk area and it would add one heck of an excellent activity, small boats, to the Weirs Beach-Lake Winnipesaukee waters.
Lake Winnipesaukee has a much larger area than 7-acre Corcoran's Pond that gets little to no motorboat use just out beyond the Weirs Beach sandy beach 250-yard rope line so's maybe that could become a happy co-existing pedal/paddle boat area that does not intercept the MS Mount Washington or the motorboat traffic, just outside the large swim area rope line. It seems like a good fit and a good use with people on the sandy beach able to walk the 300-yards down the shoreline to get to the pedal/paddle boat, sup, kayak, canoe rental business and then paddle it back along the outside water area along the beach rope line.

Correction: The four seat pedal boats have seats for four adults and a small fifth seat for a young child that is between the two rear facing seats, so it is actually a five seat pedal boat.
