To install on the davit I took the outer part off and took it to a stainless workshop and they welded on a plate with holes so I could bolt the bracket. There was one external hole I made next to the davit support . See picture, have to be careful not to put the hole on wrong side of internal support. Then I ran through the hole with the wires and heating
tubes - a bit hard to push through the foam but got there. Next took bedroom side panels
off for access hole. Easy to run all the way to nav table after getting through the foam. 40ft wire. 5 bar signal nearly always.
