Race day

Everyone answers in one tap

The skipper picks the day and who to ask. Each sailor answers each day, and Sail suggests who sails where from the positions they're comfortable with.

  • A lineup from who said yes, ready to send
  • The lineup by email, with a calendar invite
  • Reminders before the race, and an open seat offered two at a time: the first yes takes it
Who’s in, and the lineup
What needs you next
The season

The club's races and the weather, already in

The fleet's calendar is built in, and every race day comes with a forecast made for sailing.

  • Racing, maybe or not, for every race on the calendar
  • Wind, gusts, the tide and the best hours to sail
  • Results after each race

The crew

Talk to the crew without passing numbers around

A board for each boat and one for the fleet, and private messages between sailors. Nobody sees anybody's email address.

  • Conversations with one person or several
  • Reply to the email and it lands in the conversation
  • Boards send no email at all

Race tracks · Beta

Record the race, then replay it

Record your track on the phone, or bring one in from a watch. Every boat on Sail that sailed the same race replays together, with who was ahead measured along the wind.

  • Records with no signal; the track stays on the phone until Stop
  • A GPX or TCX file from a watch, split into races and trimmed on one screen
  • Lengths ahead or behind, and who is gaining, minute by minute
  • Nothing is shared live unless the boat turns it on
The replay, on the phone
Who was ahead, and by how much
Between races

Get better between races

Training games on the phone, the racing rules in plain words, and a logbook of how the boat was set up.

  • The beat: five tactics lessons against six computer boats, or race your own crew
  • Right of way, the start, main trim and rules trivia
  • The rules our races sail under, with the flags drawn
  • The base tune, each day's settings, and when gear is due
The beat: tack or hold?
