The keys to early planing are board width and sail size (but a drafty, deep pocket free race sail vs a full on racing sail with less draft and lots of twist at the top).
So, a formula board at 90-100.5 cm wide will plane much earlier than your 79 cm wide 144 Futura.
As for "free riding" on a formula board. you can for sure use a slightly smaller fn and a big drafty 10.0 m2 rig and get planing about as early as anyone, but you will need to learn to pump well.
Getting a formula board to "pop" onto a plane is a skill unto itself. Not difficult to learn, but something that takes a bit of time to get all the little moves and timing correct.
Once you are sailing, the formula board will not jibe quite a nicely as you Futura, but given alot of practice you will learn to jibe the formula board pretty well.
In near perfect conditions your Futura will probably be a bit faster on the top end, but formula boards seem to post speeds around 28-30 knots fairly often on GPS Speedsurfing, and on a 100.5 cm wide board with a huge sail that's almost scary fast.
What you will find on the formula is that you can sail it in a much wider range of conditions, but sailing a big wide board and huge sail will be significantly more "work" than you would need in the same conditions on your Futura 144, but you will not get the extreme range out of your Futura.
Hope this helps,
