No, the Phantom and the Exocet Kona's use a pin supplied to Cobra.
I tried many different pins on the original Phantom's I had last year, and the only pin that
fit was the Exocet Kona.
Fortunately the Exocet folks were at the same dealers demo or the Phantoms would not have gone on the water due to no mast bases.
The company that makes the pin and base assembly for Cobra has a very nice setup that you should be able to order from your local Starboard retailer.
Hope this helps,
