About Us

Cape Cod Marine

Like the Cape Cod waterfront, Outermost Harbor Marine has evolved over the years to keep pace with the needs of local boaters.

1950’s – 1960’s

  • As early as the 1950’s the inlet now known as Outermost Harbor provided shelter for a few local beach goers and striper fishermen.
  • In the 1960’s Horne’s Marina (as Outermost was then known) became more established through bulkheading and dredging of a basin roughly the size and shape that it is today.

1970’s – 1980’s

  • Through the 1970’s and 1980’s Horne’s Marina and then as Outermost Harbor Marine, LLC was a significant service center and base of operations for a large portion of Chatham’s commercial fishing fleet.


  • The 1990’s brought a gradual transition from a predominantly commercial to recreational facility.
  • In 1998 Outermost Harbor Marine (OHM) was established and the customer was crowned king. Since that time OHM has been focused on continuous quality improvement and creating the ultimate boating experience.
  • In 1999 we became affiliated with Cataumet Boats, Inc. of Bourne, MA in order to provide Grady-White service and sales from Hyannis to Provincetown. Since becoming a Grady-White satellite dealer we have been honored to receive their Admiral’s Circle Award for excellence in sales and service every single year. Additionally, we have been Gold Anchor Award recipients as the highest sales Grady-White dealers in the world for the past three years!

Into the 21st Century…

  • In 2001 OHM became a full-line Yamaha outboard motor dealer and our technicians have earned us a reputation as Cape Cod’s highest in Customer Satisfaction. On our staff we have the Lower Cape’s first and only Yamaha Certified master Technician…one of only about 80 in the United States!
  • In 2003 the Southeastern Economic Development Corporation honored us with their “Small Business of The Year” award recognizing our commitment to employment growth and business excellence.
  • Through several expansion and upgrade projects at both our waterfront facility as well as our inland service and storage facility (including new and expanded slips, utilities, construction of a new detailing service center complete with solar panels, bulkhead replacement, development of dry rack service to name a few) we have developed the ability to efficiently and consistently exceed the service expectations of hundreds of Cape Cod boaters.
  • Since 2012 Grady-White Boats has presented Cataumet Boats, Inc. in partnership with Outermost Harbor Marine with their two most prestigious Gold Anchor Awards for Largest Sales Volume Dealer and for #1 Customer Satisfaction worldwide. Receiving a perfect score of “10” on every customer satisfaction survey! Outermost has continued to receive this award during 2013 and 2014.
  • Outermost again in partnership with Cataumet Boats has also received an award for selling the most Grady White boats world-wide for 3 consecutive years, 2012-2013 and 2014.

  • In 2014 the Kahn family became the new owners of Outermost Harbor Marine and will be continuing the excellent track record of providing the best customer satisfaction and quality experiences possible. They bring with them their long history of successful business ventures.
  • In 2014 Outermost Harbor Marine was voted best marina in Chatham!
