i believe at one time, if memory serves me correct, there was a manufacturer that actually produced wake tanks that you could install underneath the platform? i remember seeing a handful of boats that had them in the pre-factory ballast days? either way, looks like it might work, if you don't mind giving up platform for a sac and also place all that added weight on your transom.. but there is the chance of losing it too? oh well, the curl might be worth it..
