SAFETY AND ACCURACY

• Anchor watch now shows which way you have drifted correctly. The drag alarm itself was always accurate — it measures distance, not direction.
• Route depth checks now use the shallowest charted depth on each leg, so shallow water that was previously missed is flagged.

ROUTE PLANNING
• Depth warnings now separate legs that are definitely too shallow from legs that only might be.
• One warning per leg instead of one for every charted depth area it crosses.
• Warnings clear as soon as you move a waypoint — including while you are navigating.
• If you have not set your draft, SeaMate says so and shows charted depths without guessing whether they are safe for your boat.
• Setting a waypoint as your route start no longer leaves a duplicate pin behind.

ON THE WATER
• Cross-track error reads in your chosen distance unit instead of thousands of feet.
• The anchor drift indicator moves smoothly and reacts to smaller swings.
• The chart no longer tilts into a 3D view by accident, and holds still while you drag a waypoint.

ALSO
• Tides now work offline. Download a chart pack and tide predictions come with it.
• Distress calls use your saved vessel profile. Worth opening Settings → Vessel Profile to check yours is current.
• The chart's draft picker shows the draft currently in effect.
• Corrected artwork for shark species in the fishing guide.
