Speaking as the designer in question (I wrote the Ork ship rules), I gave the Ork ships so many prow weapon slots because Ork ships in BFG have the greatest concentrations of their firepower mounted in prow slots, and they're more powerful than their port and starboard slots because Orks, unlike the Imperium don't employ heavy broadsides as their primary source of firepower - the majority of guns, (both in terms of number of weapon components, and in terms of the potency of those components) on an Ork vessel are, and will always be, on the front of the ship, fitted in whatever haphazard and rediculous manner the Mekboyz and the Kaptin desire.
Giving the Orks heavy broadsides and weak prow guns would have gone against everything that defines Ork starships. Ork ships intentionally have potentially ludicrous amounts of firepower, on tough but comparatively slow and graceless hulls fitted with heavy prow armour; the easiest way for an Ork ship to use its guns is to hurtle full speed ahead towards the enemy and unleash hell at short range, relying on heavy armour and above-average hits for their size to weather enemy return fire.
