Inspirational Crewman&ever a temp ability's will be in use at space?

1st about Inspirational Crewman BOFFs...spend about few hour over the net and only explanation is "...Bridge Officer Abilities, gain +2 to Most Starship Skills for 15 sec (may stack up to 10 times)... "Well...nice BUT for god sake what are these "MOST STARSHIP SKILLS??? If anyone end up with answer of it is most welcome to share .cause i swear this enigma for me...cant sort out if worth those boffs or i should go for others. 2nd Space temp abilitys.......lovely idea bad execution.....if my math is right.... a single vortexIII can cause as twice dmg than Timeline collapse + rapid decay...is at general this Physical Damage in space count ,cause tbh aint notice much of digits in it at parser"STO combat meter"or just i cant use them in proper way(bare on mind i do use them after at least 4 bars entropy builds)?
