About Us

Cow Island also prides itself on our gourmet meals prepared by our Executive Chef in our full- service professional kitchen. He can create anything from a simple lunch to a traditional Maine lobster bake.

We also have four yurts on the island that can accommodate up to 40 people overnight comfortably as well as additional tenting space.

Cow Island’s rustic setting can accommodate a variety of groups and activities and offers something for everyone.

Join Rippleffect for a unique team building opportunity on Cow Island. Build the strength of your team with the unique opportunities we offer. Areas of concentration may include the following:

Problem Solving
Relationship Building

Our programs are designed to reflect the unique needs of each individual, team and organization and we work closely with clients to ensure that the training will most effectively meet their needs. This is particularly useful for teambuilding, leadership development, employee orientation and seasonal gatherings.


Enjoy a traditional lobster bake on our beautiful island! Our Chef will prepare a delicious meal for lunch or dinner. Depending on the size of your party we will transport your group to the island aboard our boats or through another vendor. Do you have a small group interested in a mid-week lobster bake or sail? No problem – we collaborate with our friends at the Portland Schooner Company to offer a public “Sails & Tails” experience aboard one of their beautiful schooner’s Bagheera or Wendameen several times a week throughout the summer. Cow Island can accommodate groups up to 180 for these events.
