i saw this Sponson mod thread a week ago and it put me off buying her, i wonder why the stock hull has it flat; most odd, because all the cats i've seen are as per your excellent mod.
in addition, the bloke from AStec told me, that there is something wrong with her hull that limits her top speed, i think she needs reinforcing inside, this is even odder, because this guy was trying to sell her to me

but you've strengethened yours inside, so she'll probably be ok., this is the one us Brits call the HOR APPARITION, she's quite popular, she's the same hull as the VENOM ( i think)
