About Harbor Commons
For the people who carry it
Harbor Commons exists for the people who carry sailing organizations — quietly, repeatedly, and usually without a clean name for what they're carrying. In every club, program, fleet, foundation, and association, there's a carrier class of practitioners: the waterfront staffer who closes every loop, the volunteer who rebuilds the regatta plan at midnight, the treasurer who inherits an insurance renewal with no context, the commodore who is simultaneously governing and buffering everyone's anxiety. The work that makes the mission real is rarely the work that gets celebrated.
We've been in those rooms — as staff, volunteers, and operators. One structural pattern became obvious: the ecosystem keeps reinventing the same fundamentals in parallel. Awards, safety protocols, onboarding, insurance language, budgeting, committee handoffs, renewal comms, board reporting — solved again and again by good people, often in isolation, often with thin tools, often under time pressure. That repetition isn’t a moral failure. It’s what happens when a field has enormous care and competence but limited shared infrastructure.
Much of the most useful intelligence is already public: Form 990s, 990-EZs, 990-PFs, and their schedules. The problem isn't access — it's legibility and reuse. Harbor Commons makes that public record usable: visible, legible, and eventually queryable, so practitioners can understand their own organization longitudinally, compare across similar orgs regionally or nationally, and ask better questions with receipts instead of hearsay. We call the outcome quiet yield: small, respectful infrastructure that reduces duplication and anxiety, gives practitioners back time, and gives boards better questions — without requiring anyone to be a hero. This is practitioner-built: designed by people who’ve had to run the meeting, close the loop, and inherit the mess.

About the data
Harbor Commons tracks 2,100+ sailing- and blue-space-related tax-exempt organizations across the IRS ecosystem — including yacht clubs and sailing clubs, community sailing organizations, youth and scholastic sailing programs, sailing foundations, class and racing associations, and Local Sailing Organizations (LSOs). Of those, 1,200+ currently have machine-readable e-file returns (Form 990 or 990‑EZ) with financial data displayed on this site.
This is an approximate count: the IRS corpus changes over time, and some organizations file 990‑N (postcard) or paper returns that aren't available as machine-readable data. Some filings may exist as PDFs or scanned public inspection copies; those may be present as source documents even when structured tables aren't populated yet. Coverage expands as the IRS releases additional e-file data (typically with a 6–18 month lag).
Harbor Commons is sailing-first, not sailing-only. We include a small number of adjacent organizations when they have a clear, material connection to the sailing ecosystem in a region.
If your organization isn't listed, send us a signal. If it has a sailing or blue-space component, we'll work to add it.
