The Nial was printed with hull 3, but corrected in the FAQ to 4. Since the Shial was based on the Nial (I suspect the stats were copied/pasted then modified), should this also have hull 4?
As it is, the Shial seems rubbish compared to the Nial. It trades a point of hull and an AD of weapons, for an extra 1" movement and 6+ stealth... well the movement is a bit superfluous since 15 is quite enough for most engagements, and the stealth bonus doesn't help it in dogfights or against AF fire - only against ship weapons, which are easy to dodge anyway. As it is, it is much less of a threat to capital ships than a Nial: easier for AF to kill it, and it does less damage itself. It seems to be totally role-less, outclassed by the Nial in every regard. Hull 4 would fix it.
