Gundalow Company

What Gundalow Company does

Gundalow Company is a 501(c)(3) nonprofit organization founded in 2002 and headquartered in Portsmouth, New Hampshire. It operates the PISCATAQUA, a 64-foot US Coast Guard-certified flat-bottom gundalow described as the world's only operational Piscataqua gundalow. The vessel was constructed in 2011 following the raising of $1.2 million in capital. The organization runs a seasonal sailing program from May through October, serving more than 10,000 participants annually, including approximately 8,000 public participants and 2,000 students. It is staffed by 11-15 full-time and seasonal employees supplemented by more than 140 volunteers.

The organization's revenue model is diversified across multiple streams: ticket sales for public sails, private charter bookings accommodating up to 46 guests, school program fees (which the organization notes cover less than 25% of program costs), summer camps, a tiered membership program priced from $100 to $1,000, corporate sponsorships, donations, and gift shop merchandise. Sponsorship relationships with Service Credit Union and Newburyport Bank are cited as current funding anchors.

The organization maintains partnerships across the Seacoast region's maritime, educational, and conservation ecosystem, including Wood Island Museum (supporting a stopover sail product), Strawbery Banke, and the Great Bay 2030 collaborative. Operational legitimacy is reinforced through annual US Coast Guard certification, and the organization has invested in modernizing its registration infrastructure via the Camp Brain portal. Customer and partner segments are split between individual consumers, K-12 schools, and regional corporate and institutional sponsors.
