I am Captain Karl and I love the
water, boating, and maps. When I put
my boat "MARTINI" in Brunelle's
Marina on the Connecticut River in
South Hadley, MA, I realized there
was a need for a detailed guide to
this wonderful river.  I have spent the
last eight years researching the river
and surrounding area to create these
six guides.  I hope you find them
helpful in getting to know the river
Here is my research vessel MARTINI.  
It is a Key West 2020 with a Yamaha
115. She was not purchased as a
research vessel, but as soon as I
realized the river needed a map, she
became a research vessel. She has
also been to Long Island Sound,
Montauk Point and Great South Bay,
the Erie Canal to Lake Ontario, the
Champlain Canal to Crown Point, and
Labor Day weekends in Rockport and
Gloucester for the schooner races..

    beauty, wildlife, history and recreation available on the river.  Please go to the

    aerial photographs and details on hazards and deep water.
