An aid to planning
Wrackline is an aid to planning, not a substitute for an official tide table or local knowledge. Weather moves the water; always check conditions before you go. Predictions are harmonic calculations and do not include the effect of weather except where surge watch says so.
Pro subscriptions
Pro costs £2.99 a month or £18 a year and renews automatically until you cancel in your store account. New subscribers get a 14-day free trial. Refunds are handled by the store you paid.
Club licences
A club licence covers up to 40 members for twelve months at £210, invoiced to the club. Members can be changed at any time.
Liability
We take care over every prediction and publish our error for every port, but we cannot accept liability for loss or damage from relying on a prediction in place of official tables, local knowledge and your own judgement.
