Southwest Michigan's Lake Family Resource. Since 1999.
If you boat on a lake in Southwest Michigan and you are serious about riding, buying the right boat, or keeping your boat in good shape year round, this is where you come.
WHO WE SERVE
Southwest Michigan is lake country.
Van Buren, Cass, Berrien, and Allegan County are full of inland lakes. Families spend their summers on the water here. Kids learn to waterski. Teenagers get into wakeboarding. Parents upgrade from pontoons to wake boats. Boats get stored, serviced, and eventually replaced.
The Boarder Line has been serving those families from Round Lake in Sister Lakes since 1999. We are not a big box store. We are not a franchise. We are a small operation on a lake in Southwest Michigan that has been doing this for 25 years because we love it and because the families who come back every summer trust us to do it right.
We are the only place in Southwest Michigan where you can take a private lesson, buy a Nautique, store your boat through the winter, and pick up the right gear all in one stop.
