A lot of info regarding the hull designs over the years on the MBG site. Basically, the Mirage 1 was Maverick's intro into the "technical poling skiff" market in 92. Boat hull was reportedly derived off the Banana River skiff, and the original SuperSkiff hull design. Hull had a following--quiet, poles well. They redid the hull and deck in 96/ Basically same hull, but addressed issues with the 1. The HP came out in 98 as their transition to the HPX line. Still more or less the same hull as original Mirages 1 and 2. Less freeboard and weight. HPX-V is their current hull--updated hull/build methods--much lighter hull. Many believe this hull as the best overall compromise for ride/poleabilty for it's size. Don't believed it has changed much since intro in 2001 in design. Maybe different build methods, addressing heavier engines, etc. Their V2 is just updated deck layout. All boats were basically designed for the areas I'm assuming you're fishing--Biscayne Bay, Key's/Florida Bay...
Of course there are their variances off those hulls--the Micro, HPX15, HPX Tunnel, HPX 18--am sure I'm missing a few--tight lines!
