Hate to burst your bubble, Tagan, but I'm betting that the Kobras Aquiarre, on Solar Sails alone, actually has a -30 maneuverability, not it's normal +33 minus 30, but an actual figure of -30 to add to your actual skill... which would make you have to roll against a modified skill bonus of 65.  Of course, rolling a 19 means you managed to get 4 extra degrees of success.<br/><br/>Of course, the question is, what did you want to DO with that?  You needed to get up to a speed of 3, which means you need to spend one success minimum on increasing speed... leaving 3 more extra degrees of success to spend on evasive maneuvers... but unfortunately, just making evasive maneuvers adds -10 to the difficulty, so you only have 2 extra degrees of success, which gives a total -20 to the incoming torpedoes chance of hitting with that test... much better than nothing, of course.<br/><br/>Unless of course TGT meant that the Kobras Aquiarre is actually -30 off of it's normal maneuverability of +33... giving it a +3 total maneuverability modifier... in which case you would have gotten 7 degrees of success, and give a total of -50 to the incoming torpedoes attack rolls... which would be great!
