I will use NUC8I7HNK in a Boat. The AC power of the NUC is 19v 11amps . I have only 12v on the boat, so i think i will use DC-DC step up converter from 12V to 19V 15 amps (285w), exact reference is Xw-12-19-285w. It is safe to use this step up with NUC?
This converter look OK. You should make sure to connect the wiring correctly to the input connector. Please refer to para.2.5.1, page 52 in the Technical Product Specification https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HNK_TechProdSpec.p...
