Vieste to Tremiti Islands
North across open water from the Gargano to the Tremiti Islands, a small archipelago of pine-covered limestone with an abbey fortress on San Nicola, to a park mooring between San Domino and San Nicola.
About 15:25 CEST at Tremiti Islands. In the afternoon, with about 5 hours of daylight in hand (sunset 20:24 CEST).
Tides
Range about 0.2 m: no practical effect
Wind
The maestrale is on the beam; boats must leave the park's buoys above force 4
Boat
35 to 38 ft sailing yacht, 1.9 m draught, 6 kn under sail, 5.5 kn under engine
Crew
Skipper and 3 crew, 2 watches of 2
Track and waypoints 1 to 2, with ports of refuge as squares.
Go or no-go
Decide at 08:30 CEST. Go only if all of these hold:
No wind above force 4 forecast for the 2 nights at the Tremiti: boats must leave the buoys above force 4, and there is no all-weather harbour.
Park mooring booked for 9 and 26 July.
Visibility 3 nm or more.
If the forecast is wrong, stay at Vieste and go on to Pescara along the coast via Termoli, leaving out the Tremiti.
Route and waypoints
Waypoints are planning positions in open water, checked against a 1:10m coastline to be at least 1.5 nm off land except at the harbour ends. Distances and courses are calculated from them. Plot every one on the current chart before use. Courses are true.

From the Isole Tremiti station.
Sunday 25 July 2027. Tides. The range here is 0.1 to 0.3 m: tides make no practical difference. Wind and air pressure move the sea level more than the tide does.
Tide times are predictions made for this plan from the TICON-4 harmonic constants (DGFI-TUM) with the Neaps tide predictor, because the official 2027 tables were not yet published when it was written. Tested against the official APDL table for Leixões on 23 July 2026, the predicted times were within 8 minutes and the heights 0.1 to 0.2 m lower. Heights are above lowest astronomical tide. Check every time against the official 2027 table before sailing.
Daylight. Sunrise at Vieste 05:42 CEST. Sunset at Tremiti Islands 20:24 CEST.
Weather
Open water for 25 nm.
The islands give little shelter; the buoys are in the channel between San Domino and San Nicola.
Forecasts to check
Italian forecasts: Aeronautica Militare Meteomar and gale warnings (avviso di burrasca), meteoam.it. Forecast areas Ionio, Adriatico meridionale and Adriatico centrale. Zone names and issue times: Check the pilot book
NAVTEX: Italian stations cover the Ionian and Adriatic; check the station letters and times on the receiver. Check on the chart
Italian coast radio VHF weather broadcasts: Check the pilot book
Hazards
Isole Tremiti marine protected area. Zone A, round Pianosa, is closed to all boats. Zone B: sail is free; motoring needs a permit from the Gargano National Park (€10 per day in 2026), and the limit is 5 kn. Zone C: 5 kn within 300 m of the coast and 10 kn out to 600 m; anchoring on sand or pebbles only. Motor boats may not enter the sea caves. The park's mooring buoys (May to September) must be booked online; in August 2026 a buoy for a boat up to 15 m cost €80 per day. One boat per buoy, an all-round white light at night, a holding tank to use the heads, no swimming from the mooring, and boats must leave the buoys above force 4.
Ferries and hydrofoils from Termoli, Vieste and Manfredonia land at San Domino and San Nicola.
San Domino light. The Punta del Diavolo light tower was reported collapsed in 2025. Do not rely on it.
