Night water. Golden traces.

Leave your mark
on the bay

Bay Trace is a ride journal for the water. Draw the line you took, watch familiar routes glow, and read the tide before you paddle out.

The craft

A logbook that lives on the water

Every session becomes a glowing trail. Heat, fog, ghost lines and tide windows turn a quiet bay into a map only you can finish.

Draw the ride

Trace your line across Kelp Bay, Shell Point or North Reef. One gesture captures the shape of the session.

Heat on repeat

Routes you ride again burn brighter. Rare lines stay faint. The water remembers how often you pass.

Tide windows

Plan the hour, simulate swell and wind, and keep alerts on the phases that treat you best.

Shape of your style

Glides, carves, cutbacks and airs stack into a portrait of how you actually ride the bay.

Ghost lines

Earlier sessions linger as silver trails, so tonight’s ride sits on top of everything you already learned.

Marks that stay

Drop peaks, hazards, entries and rest spots. The map becomes a private harbor of notes.

Four beats

From first spark to open water

The same frames you meet on first launch — welcome, draw, layers, ready — now as a full visual walk through the bay.

Live chart

A bay that fills in as you ride

Sunlit water, reef shadow and foam along the shore. Fog lifts only where you have been, so the unexplored stays mysterious until you draw through it.
