Received this email from the BoatyBall folks this morning. Anyone know what the "new" fee is?

"We wanted to thank you for being an early adopter of BoatyBall. We have taken your feedback and made a number of changes to improve the overall experience. During this 6 week pilot phase we have had over 900 boater accounts and over 900 reservations. Our number one request is to be able to reserve in advance and the biggest issue is boaters squatting. We are currently working on giving boaters the ability to make future reservations. We will also be introducing a number of changes that we believe will help with enforcement. One is giving boaters the ability to make their boat name visible in the app. This will allow other boaters the ability to see what boats have reserved moorings. In addition, we will also be increasing the BoatyBall service fee starting 2/1/2019 to help support enforcement in the bays. The initial adoption of BoatyBall has been very encouraging and has allowed us to continue to develop the app. We appreciate your willingness to try this new service and we look forward to continuing to update and improve the app. Cheers, from the BoatyBall Team"
