What size blade fuse? Standard, Mini, or Micro?

I left the battery switch turned to on last time we boated and so we had a dead battery today. I hooked up the GB40 to jump start without success: after a few tries the GB40 was down to 50%, the gauge needles stayed all the way to the right, and the LCD displays stayed blank whenever I tried to cycle the ignition.

I disconnected the battery and brought it home to trickle charge before it occurred to me I might've blown a fuse trying to jump start the boat. I'd like to buy some extra fuses to bring to the marina next weekend just in case, but our SX190 is back up on the dry stack so I can't check the fuses and I can't find anything that indicates just what blade size our fuses are, only what amps they.

Can anyone tell me if I should buy standard blade fuses, mini blade fuses, or micro blade fuses?

I'd say Mini blade here is a pick of the fuse box and a 30 amp fuse, I bought variety box of Regular, micro, and Mini's at Harbor Freight and keep them on board
