LATEST UPDATE ! Purchases now only available on Android, due to subscriptions required by Apple
The website for the MarkLayer app on Playstore.
Welcome to my website. The MarkLayer app is intended for use by Race Officers and Mark Layers, for Yacht and Dinghy racing on a laid course.
Courses available are Triangle, Triangle with offset/spreader and Trapezoid. It can also be used for Windward/Leeward by ignoring the gybe/wing mark.
The app now has a Current option
BASICS of USE
For Mark bearings and distances, the app assumes that the Mark Layer has set a Pivot at the Leeward end of the course and is then positioned at the Windward Mark. If more Mark Layers are available, the outputs will enable them to position themselves.
The map page enables a Mark Layer to drive to the mark positions. It also can show the Lat/Long of each mark.
The app can be used with or without current.
Either option outputs the bearings of the Start Line. With current, this is based on the Sailing Wind. If the Wind at the Committee Boat is different from the Wind at the Windward Mark, then the app can be used in 2 ways. The RO can use it by inputting the local wind, to establish the Start Line. At the same time, the Mark Layer can use it by inputting the required Wind of the course, to enable the marks to be laid
The app has a full list of FAQs

WHY DO YOU HAVE TO PAY FOR IT ?
It could be free if I put advertisements on it, but this would be a major distraction when using it for a race. Unfortunately, production has cost a significant amount; Vat is payable on the price and Apple & Google take 30%.
