The important information, readable between yacht and shore.

Designed for glare, spray, and motion

General-purpose map apps are useful on shore, but a tender ride asks different questions. What are my coordinates? How fast am I moving? Where did I leave the yacht? What is the tide doing? TenderTo keeps those answers together in a high-contrast display with large type that works in portrait or landscape.

GPS position and speed that make sense afloat

Position is shown in degrees and decimal minutes, a format cruising sailors can relay easily. Speed is displayed in knots. TenderTo also accounts for the small GPS movements that can appear while a phone is sitting still, and it reserves the live speed display for an active trip.

Apple Maps with a NOAA chart layer

The map combines familiar land context with available chart display data provided by the NOAA Office of Coast Survey through the NOAA Maritime Chart Service. That matters because a dinghy trip connects two worlds: the water you cross and the streets, docks, restaurants, and services you explore after landing.

Honest surface detection

TenderTo can use Apple location data to confirm recognized water. Near shore or on land, automatic classification may remain unconfirmed. During an active trip, use the manual On Water or Ashore control when needed. TenderTo never uses speed to guess the surface.

A visible route back after dark

An active trip leaves a recorded track on the chart. On a nighttime return, the crew can follow that outward track in reverse instead of relying on an unfamiliar shoreline alone. The saved Home Vessel point and straight-line distance provide additional context as the tender heads back.
