What a regatta result does to your average and rank, calculated before the start.

• A sailor's average and rank from the official ranking list
• Scenarios: "place X at this regatta, new average and rank"
• Form curve over the season

Your whole training group at a glance: ranking, progress, regattas and the season report.

• The group in the ranking: rank, points and movement per sailor, across clubs
• The group in the field: top and breadth, scored as a club
• Compare two or three sailors directly, light and strong wind per sailor

Which boat goes on which trailer, who tows which trailer: trailer planning for regattas and training trips, there and back.

• Parents sign up via a link from the Spond chat: which child, there and back, whether they can tow
• Assign boats to trailers and drivers to trailers, separately for the outward and return trip, automatically if you like
• The plan goes back into the Spond chat as text; parents see which trailer their child's boat is on

The Apple Watch keeps open-water swimmers on a straight line, with taps on the wrist.

• One tap: go right, two taps: go left
• A corridor with thresholds at 15, 25 and 40 metres
