Sculling Academy products are unconditionally guaranteed for 90 days. If, before the end of 90 days from your purchase, you decide you are not satisfied with the course material that you are receiving, then I will give you 100% of your money back and you can keep everything that you have downloaded up until then. It is my way of saying thanks for giving it a try. We know that there may be a few unscrupulous people out there who will take advantage of this. But we also know that most people and especially boating people are good honest people who would never do that and I am confident that you will be bowled over by the content that Sculling Academy provides so this is why I am able to provide this 90 day guarantee.
