Competitors publish static content; LeeHarbor computes it: "can this boat enter that cove, on this date, in this weather — and is there a marina fallback?" 2,238 marinas, live AIS, marine weather, sea-routing, safe-haven advice and boat & yacht charter — all on a single map.
Everything on the map is real data — no made-up marinas, no fake reviews. All figures from the live production database.
These are not scraped prose but server-computed values — a rival cannot get them by copying a page. And each compounds with the others: routes link to coves, coves to charter, charter to marinas.
The number of reachable, sheltered coves filtered by the boat's real draft — the charter marketplace's signature filter. No aggregator exposes this.
✓ LiveA live safety score read from a cached Mediterranean weather grid (~857 points, refreshed ~every 3h) — a computed answer, not a per-render API storm.
✓ Live“⚓ N boats anchored” + hour×day marina occupancy from a persistent AIS listener running for weeks. 50,784+ records and growing.
✓ Live40 coves with real depth/bottom/holding/shelter fields and 6 blue-cruise routes — all cross-linked. An internal-link and data-completeness graph rivals lack.
✓ LiveThree sides share one sea: those who set sail, those who run the marina and those who service the boats. LeeHarbor brings all three together on the same map — and builds a dedicated world for each.
Map, weather, routes, logbook, fleet management and berth requests. Know everything before you drop anchor.
Boat owner page →A free marina operating system: berth requests, reservation ledger, pontoon status and pricing.
Marina operator page →Reach the boats anchored in the cove. Build your profile, draw your coverage area; let boats find you, call you and share their location.
Service provider page →LeeHarbor doesn't guess; it combines open, trusted maritime & weather data sources on one screen — most served straight to the client, cached in the background.
At the heart of LeeHarbor is a GPU-accelerated WebGL map engine — globe projection, 3D terrain and animated wind run cheaply on top of it. Every layer is current and location-aware.
Marinas, fishing shelters, mooring fields, restaurant jetties, day coves and town quays — every place a boat can berth is on the map. Zoom out to a real globe, in to the flat nautical chart.
One-tap sphere projection and relief terrain; wind particles are re-projected onto the curved surface — a visible edge over flat maps.
Switch between high-resolution satellite imagery and a street/nautical basemap — read the cove bottom and approach by eye.
20+ layers (navigation, depth, traffic, coves, weather) toggle in grouped panels; every new data wedge plugs in here cheaply.
OpenSeaMap navigation marks (IALA), EMODnet depth contours and VHF approach channels — revealed on zoom, with a captain's legend.
39 bespoke “brass & glass” marine instrument icons physically animate when live data arrives — a proprietary visual language vs generic system icons.

We turned 2,342 static SEO pages into live decision pages: a server-rendered “can you sail now?” block on every marina, cove and spot page — zero external API at render time (369-node cache).
Neither Navily/marinas.com (static) nor Windy/MGM (raw) offer this: each page shows that spot's live safety score, weather/sea state and ⚓ AIS anchored-boat count. Open to Google, live for the user.
AIS positions of the commercial and private boats around you on the map, live — a feed learning from 50,784+ position records.
A crowding indicator for every cove: “⚓ boats anchored · busy/quiet” — priceless when hunting for an empty corner.
Marina traffic by hour × day — learned from live AIS history; see in advance which day and hour it fills up.
“Usually ⚓N boats at this hour” + a quieter alternative suggestion when it's full.
Location- and zoom-aware — Istanbul's weather and Bodrum's never mix. From the seabed to the sky, all from a cached grid.
Particle animation at realistic speed plus a colour legend — direction and strength at a glance.
Instant wave height and swell direction; tell at once whether the cove is calm or exposed.
A temperature layer with coastal temp/wind labels and a precipitation layer — two live overlays from the same grid.
Rise and fall from real sea-level data — critical for shallow approaches.
Water depth and bottom profile of any point from EMODnet and GEBCO data.
Sand, mud, rock, posidonia — will your anchor hold? Bottom type and anchoring suitability.
Enter your draft and clearance; shallow/risky zones flag red/yellow on the map — turning bathymetry into a safety warning.
Sunrise/sunset, moon phases and solunar — for daylight arrivals, night passages and the fish bite.
Combines weather and wave forecasts to highlight safe hours to enter a harbor. Tap any map point; shelter, sunset, safety score and marine forecast open instantly.
Pick two points; in seconds LeeHarbor draws a genuinely navigable route bypassing land — with its own 1-bit land/sea mask, no paid routing API. Then it grades your route with a safety briefing.
Vector-averages the route's wind, flags exposed 18+ kt legs and detects the Aegean N-NW ≥15 kt Meltem pattern. Cross-checks shelters' protection sectors against the forecast and warns about daylight arrival.
A local land/sea mask keeps the route on water; drag waypoints and it recomputes instantly.
Flags strong-wind legs with no nearby shelter and the Aegean Meltem in advance — hyper-local safety intelligence.
Alerts when a route enters another country's waters (Turkey→Greek islands) and reminds you to report at the port of entry.
On long routes it suggests sheltered, bookable marinas for overnight stops — sending the request straight to the operator.
Saved routes and the digital logbook (CSV export) are in beta.
Two official open-data trust signals, right on the chart — self-refreshing sources no rival surfaces on the page.
Blue Flag marinas from FEE's official data show as ⚑ badges and 580 beaches as tappable cards (on by default). Marina pages get a 🏆 badge + JSON-LD “award” schema.
Curated official marine Special Environmental Protection Area polygons flag an “anchoring restriction” warning when a cove or marina falls inside one — protecting Posidonia and captains from fines.
Free authoritative data → SEO + trust. Boundaries are approximate and honestly framed with a “confirm the official source” note.
The 40 curated coves are live markers on the map: tap one and the panel opens depth, seabed, holding, shelter and the live sea state. Nearby anchorages are scored and ranked for the boat's draft.
A “will the anchor hold here” engine from depth, slope, holding, shelter and community rating.
User-added anchorages with bottom type, holding and wind protection; with comments and likes.
If a cove is inside a protected zone the panel shows an anchoring-restriction note — an honest, sourced warning.
“Anchored at Çökertme last night — mud bottom, excellent holding, light evening breeze. The north of the cove is calmer.”
“The staff are extremely attentive, the facilities spotless and the location superb. We'll definitely be back.”
LeeHarbor is designed mobile-first; it runs smoothly in your phone's browser — map, weather, routes and your panel always at hand, even at the helm, one-handed. Push, favorites and app-config services are live server-side; the iOS and Android apps are in development.
One inventory serves three demand pools: bareboat, skippered and cabin. Every listing has a first: the sheltered coves that boat can enter given its draft, and the sea window for your chosen dates.
Crewed, bareboat and cabin charter across Göcek, Fethiye, Marmaris, Bodrum, Datça and Gökova. Send a request, get a VAT-itemised quote, sign the contract and complete the handover report in-app — even messaging is per-booking, no phone tag.
Every boat answers “how many sheltered coves can this hull enter?” — a 2.4 m draft and a 1.2 m draft are not the same holiday.
Pick your dates and the wind and wave window for those days opens right on the boat page — no surprise gales.
Charter as a first-class map layer: price pins, draft-coloured coves and page↔map filter handoff; pin=card=quote parity.
The price you see is the operator's price; LeeHarbor adds no middleman markup for the renter. The operator pays the commission.
The engine that grows supply — the /yat-sahibi panel runs the fleet and revenue in-app.
Create/edit listings, extras, seasonal pricing — a ~40-endpoint operator panel.
Selectable packages and auto-applied campaign discounts (strike-through price) — lifting operator ARPU.
Race-locked date blocking and a public availability calendar — reliable inventory.
Bareboat licence gate, per-booking messaging and a signed handover/damage report — 24/24 end-to-end tested.
⏳ In development Online payment / iyzico escrow (Law 6493) — the commission ledger is built, card collection is on the roadmap.
2,238 pre-built harbor pages are a zero-cost supply funnel: an operator “claims” their marina and gets the free ERP. It moves a paper-and-phone marina onto one screen.
Claim one of 2,238 ready listings → unlock the free ERP. The supply-side acquisition mechanism.
Boaters' requests land straight in your panel; accept / quote / decline.
Inside the panel: “N boats near you” — a live AIS summary of vessels nearby, moored, busy. The reason operators return daily.
Phone/walk-in reservations, check-in/out and payment status (unpaid/partial/paid) — digitised.
A live pontoon status board + block full dates; requests for those dates are refused automatically.
Regular-customer cards, their boats and history; seasonal price rules applied automatically.
Online collection (in development), e-invoice (pending a GİB integrator account), utility metering and annual berth contracts (planned) — clearly separated from live modules.
A marine services marketplace across 19 categories. The anchored boats that never come ashore are your customers — and the revenue model isn't theoretical, it runs live.
Build your profile and draw your coverage area (base point + radius + delivers-to-boat). Boats find you on the map; “send my location” becomes a one-tap WhatsApp lead, and every lead is recorded as attribution data.
Geo-matching: radius + delivers-to-boat; map discovery → WhatsApp lead bridge.
Leads inbox, priced-quote flow and a priced-order (Deal) lifecycle — customers track their order, providers see earnings.
Verified-transaction reviews + automatic stale-deal expiry — a trustworthy two-sided market.

OSM, Nominatim, Wikimedia and Google Places pipelines; with an honesty-first UX. Instead of turning the unknown into an “Unverified” wall, it shows the known with its source.
City fill via Nominatim reverse-geocoding 6% → 85%.
Photo coverage via Wikimedia/Places images 57% → 69%.
Berth data via OSM capacity/maxdraft mapping 139 → 256 marinas.

A strong technical product and category position at a big integration threshold. Not proven revenue — an investment at the go-to-market inflection.
Yacht charter market $8.4B → $18.3B (8.1% CAGR). The Mediterranean is ~40–50% of charter GMV. Phase-1 beachhead: Turkey/Aegean, with multilingual Mediterranean search.
Honesty note: the live charter fleet is 9 boats (small but real); the ~20,000-boat Booking Manager/NauSYS inventory is an accepted next integration step — not live supply. User count is early-stage and off-page SEO is still zero.

Whether you set sail, run your marina or service boats — LeeHarbor is free for boaters. Start today and draw your first route.
