secure the tanks!!! and have a way to secure ALL gear. Being that your boat it fiberglass west marine makes a rubber or a plastic floor tile that interlocks, it provides good traction and will help save your deck from short tank drops. And again find away to keep all gear stowed or tied in place when not in use. You will find the majority of other boaters do not care you have a dive flag flying, and not only will they call it close, boat wakes have a way of injuring your divers. and use atleat a min of 10 feet of anchor chain (i use 100 feet) and atleat a 7 to 1 scope, of line, It is alot but it is nice to see your boat still anchored were you left it. Good luck and enjoy!
