| Jun 20, 2022 at 21:55 | comment | added | ouk | sure, but a recreational boat is not a ship, and above 60V, DC can in some circumstances be pretty dangerous / potentially lethal. Let alone 300V. A few large busbars and fuses sized to occasionally carry large currents on a short distance is a much lesser worry to me than possibly having 300V DC exposed if there is a fault somewhere. | |

I’m sure there must be a middle ground to routing that power safely in spite of the wet environment. 300V is not an extreme voltage for marine use, if competently done. The shipbuilding industry has all the practices you need to do it safely, and then some. I don’t recall the relevant standards offhand though. | |
| Jun 20, 2022 at 8:57 | comment | added | ouk | Sorry, but on a boat (not a ship, not a superyacht!) anything above 48VDC is unsafe, and as explained in another comment there are many reasons to stay at low-ish voltage, especially when the high current surges are infrequent. It is not uncommon to see relatively large battery packs capable of supplying 500A or more these days (a 300Ah LFP pack can easily do that - although not for a very long time). | |
