Boat Timer – June minor update

When you press the “Lap” button in Boat Timer the Lap button disappears for that boat so you know you have recorded a lap. The button reappears when you press Update on the grid to sort the race into the order of the last lap for the sailors.

To make it more obvious which boats have lapped and which have not, the latest version of Boat Timer (version 21160) also turns the boat’s box grey. So only the white boxes have yet to have a lap recorded. Just like the lap button, the normal colour is restored when you press the Update button to re-sort the grid.

As always, the update to the Boat Timer app is automatic – if you close and open the app a couple of times you should see the new version.

Boat Timer Update – Average Lap Timing

Boat Timer users will be automatically upgraded to the new version 21122 this week. This version has some minor fixes for forms and race switching and introduces Average Lap Timing.

Average Lap Timing

Previously Boat Timer used elapsed time (the time taken to go from the start to finish line) for results. However a number of clubs use average lap times instead. In this type of race, the race team sound a warning signal (similar to a “shorten course” signal) to tell sailors that the race is about to finish. The next time each boat crosses the finish line they have completed the race.

The advantage of this method is that faster boats can sail for longer in a handicap race without slower boats having to sail more laps. So it is becoming a popular way to run club races as each sailor can have roughly the same amount of time racing whatever boat they sail.

Boat Timer now supports this. In each start you can change the Timing Method from Finish Time to Average Lap Time and results will then use the average lap times and for handicap races, corrected times will be based on average laps too.

The way times are calculated is to take each boat’s average lap time and multiply it by the most laps any boat completed. This gives an elapsed time for each boat as if they had done the same number of laps. Corrected times are then calculated from the elapsed time using the rating system selected.

Boat Timer April Update

You will automatically be upgraded to the new version of Boat Timer this week (version 21100). This update fixes a couple of issues and adds a search facility to the race grid that comes in very handy when managing a lot of boats in a race.


  • The country code for China has been corrected and two missing countries Bolivia and Chile have been added.
  • The “Move Up” function now works correctly. There will be a new blog post soon to introduce you to Move Up if you have not used it before.
  • Zero is now accepted as a sail number. Previously it could not be used and an incorrect error message was shown.

New Search Facility:

At the top of the race grid there is now a search box. If you are tracking a large fleet, search helps you identify boats quickly by class or sail number. When you enter part of a class name or sail number, the matching boats are highlighted in the grid. To unhighlight, simply delete the text in the search box and press search again.

Plymouth, Falmouth & Langstone marks added to JettyMap

JettyMap can use shared marks as well as club-specific race marks where clubs share their sailing area.

Chichester and Portsmouth Harbours, plus the Solent sea marks are already mapped. Now three new areas in the UK – Plymouth Sound, Falmouth and Langstone Harbour have also been added.

You can see the shared marks when you select any sailing club in that area.

If you would like your club to be next, let us know – it can be anywhere in the world.

New version of Boat Timer released

The latest version of Boat Timer is now available. This is a significant upgrade that introduces Cloud Services sync with online race entry and results, plus many other features such as a simpler screen for adding new entries and more obvious buttons on the race grid.

A guide (PDF) to the new version is on the main Boat Timer page.

If you open the app the upgrade will be applied and you should see the new version the second time you open it.

**However** often browsers will cache the old version and – depending on the browser settings – it may take several hours before you see the upgrade. You can wait and the upgrade will eventually appear or you can clear the part of the cache that affects this.

In Chrome, the relevant part is in Chrome Settings – Privacy & Security – Clear Browsing Data – Cached Images & Files.
