As explained on the home page, Sailwave is a hobby of mine and relies on donations to keep it going.
You can also donate to the project by simply using the links below when shopping online instead of going to those sites directly. I receive a small fraction of each purchase. You could even save the relevant Amazon link in your browser shortcuts or favourites for easy access 
Many thanks,
