Replacing my power block

[SkaterRace]

I have a Blue Sea Systems ST ATO Fuse block that has 6 spots for fuses/connections. I have maxed it out and am looking at going to a 12 spot one. Phyicially it will fit but I am trying to determine if it will handle the load properly.

My boat is a Blackfin 212CC from 2019. This is the block in the head compartment inside the console and feeds the console.

I mainly want to swap it out so I don't have to run more large wire from the stern/main panel and because it would allow me to add a few more electronics, like NMEA 2k and a Mercury Link system.

It's all based on max amount of amps (load) that may be needed.

Look at the size wire that's feeding the current block and how long a run from the Battery it is. Then add up max load of each device

Thanks I checked the wiring diagrams and I am pretty sure it is either a 6 or 8 gauge wire and a 96 inch run. Worse case says I should be able to handle ~50 amps. The fuse block is rated at 100 (both old and new). The fuses I have in it now add up to 27 amps - ignoring actual load - so seems like I should be safe to add a little bit more load on it. I think I'll end up with a single 5A fuse added and possibly a 7.5A if I add in a light.
