Hulldesign, it is from Rolland, the designer from the Pogo1, so lets look at the design changes to see what happened between 1985 and 2003. See photo, top Pogo 1, under that Dingo.

Slightly higher bow and lower stern. More sharp bow, and more curve back at the end (look at hull lines near rudder). Rudders more from centerline.

According design laws: a bit less nose diving (a small pogo1 problem), bit faster upwind, bit faster in light winds, probably it is lighter then the pogo1, so it should be faster reaching.
Romain Vidal a Pogo 1 and Dingo sailor says this is all right, and even claims to be faster on a plane in light wind then a SuperCalin...

Comments from Romain Vidal, Pogo1 MT sailor, then Dingo in last MT:

"Concerning the cockpit and deck, it is totally different from the others series, and closer from zero with a deep cockpit feeling more safe against the elements, and better for the legs. Also, with the little "wings", the instruments are protected. The deck is simple and clear with a good deckline. The mast is the same as the pogos. And the "bout dehors" is quite the same.
Inside also is completely different from all other 6,50. this is due of the "bannettes" and their systems such as figaro 1 got. We can move the level of the bannette in order to be horizontal. There is no "coffre" (place occupied by the floatability alongside), only the bannette. The floatability are placed completely at the back of the boat making some place in the living area. The map table is placed just behind the mast closing the batteries system. The gaz system can be attached around the mast like pogo2."

I do miss a portlight though, must bit a bit dark inside, but easy fix.

This sleeping arrangement is a personal choice, you either like it or hate it. And nobody says you have to sleep in it :) BUt for a cruiser function it can be limiting.

Battery box and chart table, placed where it counts, around the keel area, some series have them under the entrance, not the best place for weight distribution.
You see reinforcements, on deck and hull, only bulkhead connects deck and hull, easier to make then fully laminated structure.

Rolland found a loophole in the foam department, it should be fixed, so he placed it under a plastic cover. Its al over the back on the floor. Could not believe the Classe mIni allowed this :) Nice find Rolland. You will have sailors cheat and remove foam, security team will see it, discussions will start :) Same for the loose foam in the back of the P2, i have seen boats with it taken out...
Because you want to check the rudder bolts, they are now hidden...

NIce clean step inside.

Here you see the wings, and cockpit. Cockpit is deeper, but not to long (you have to make compromises)

Overall, it looks like the yard wanted to build an easy to produce boat to compete with the P2 on the French market, simple stringers combined with embedded structure, keel foil end in plate bolted to hull, loose foam, easy to bold in beds. It wanted better light wind speed, were the P2 has some weakness. A less racy (more protected and comfortable) cockpit. One tiller to free up space. Its all different in small details, only the berths and foam really stand out.
Some will like it, some will hate it.
