FOR CHARTER CAPTAINS · ADRIATIC FIRST

A first mate for charter week.

Mermaid reads the wind, routes around the ugly parts, and stands the anchor watch all night — so a week a year on the water feels like your hundredth season.

01Forecast

See the wind before you feel it.

Gust fields render over the real chart the way sailors think — color for strength, particles for flow, bending around every headland. Scrub the next 30 hours, tap anywhere for a point forecast, or zoom into Splitska vrata and watch the channel squeeze the Jugo.

02Planning

Two answers to “how do we get there?”

Fastest gets you in early. Comfort keeps the crew smiling — Mermaid weighs wind, gusts, and wave height and direction against your actual boat. A 1.4 m beam sea means nothing to a ferry and a rolly, queasy hour on a 42-ft monohull — so the router knows the difference.

03Seabed

The seabed, in 10-metre detail.

Official charts give you a handful of isobaths and a letter — S for sand, M for mud. Mermaid’s satellite-derived bathymetry maps depth and bottom type at up to 10 m: isobaths every two metres, and seagrass meadows drawn with the sandy holes where the hook belongs. Drag the divider; flip the layer.

Isobaths every 2 m on the Mermaid side — drag the divider

anchorThe anchor alarm reads the same layer — holding advice knows if your hook is in sand or weed.
04Anchor watch

Sleep. Mermaid keeps the watch.

Confirm the drop, set your chain, arm the watch. Mermaid computes the swing circle from chain, boat and GPS error — and if the hook drags past it, every phone aboard wakes up. All of it in amber, because night vision is a safety feature.

05Charter check-in

Evidence, not arguments.

The AR wizard walks the boat scene by scene — hull, sails, cockpit, engine bay. Every photo is guided, timestamped and synced; damage gets outlined right on the frame. Your deposit’s best friend, at check-in and at return.

Right-moment questions
One-tap ratings when context is fresh — they feed the local knowledge below.
07Local knowledge

Reviews that were actually there.

Every bay, buoy and konoba rated by crews Mermaid can verify were on the spot — and asked at the right moment. The skipper gets “did the anchor hold?” after a night on watch; the crew gets “how calm was the bay?” over morning coffee, or “worth the swim ashore?” after three hours at the beach. No drive-by reviews.
