Data methodology

Marina catalog

Our marina catalog is built from many trusted sources:

• State DNR and harbormaster registries.
• USACE navigation databases and NOAA chart data.
• Marina-published websites and dockmaster calls.

Marina record

Each marina record stores key trip-planning facts:

• Coordinates, slip count, max LOA, and max beam.
• Controlling depth and shore-power options.
• Amenities and status flags (liveaboard, transient, hurricane-safe, looper-friendly).

Pricing

Pricing reflects ranges seen across published rate sheets and dockmaster calls in the past 12 months. We publish ranges, not single prices, because:

• Rates change by season and contract length.
• Slip type and electricity inclusion change the total.
• Marina-specific prices are only shown if the marina confirms them in writing.

Amenities

We tag amenities from a standard internal taxonomy (fuel dock, pump-out, pool, laundry, restaurant, repair, 100A power, Wi-Fi, and more). A tag is only added when we confirm it from:

• The marina's own website.
• A state Clean Marina record.
• A direct dockmaster call.

Depth & beam

We publish controlling depth at mean lower low water (MLLW) when we can. If MLLW is not available, we show the marina's self-reported depth and label it. Always verify depth at low tide before you book.

Weather & tide

Weather, wind, tide, and visibility on the site come from deterministic models tied to location. Use them for general planning only. They do not replace:

• NOAA marine forecasts.
• Official tide tables.
• Current local observations.

Update cadence

We refresh data on a clear schedule:

• Marina records: continuous user reports plus a 12-month audit.
• Pricing pages: reviewed twice a year.
• Weather and tide data: updated on every page load.
