It does indeed look like a Pro 530 (look identical to mine). From what I understand, there was a Hurricane version which was pretty much identical, although may have been a thicker hull construction. Check the identification plate as this will confirm either way.
These are good boats for better weather/clamer days and mine makes good progress with 6 on board and a modest engine on the back. The wide beam gives masses of deck space and a stable platform for divers/fishing etc but gets a bit uncomfprtable under heavier seas, although still quite capable. The "outriggers" for want of a better description seem to keep the boat very flat through the turns, however it is still very manouverable.
As mentioned earlier, the tubes are pvc and are still available for replacement. Mine were replaced about 4 years ago, making the boat look almost new again.
Hope this helps,
