I'm working on a Catalina 25, 1974 vintage. The existing motor starter leads are being led down the port vent into the port lazerette. Here they go forward through the same 4" hole (at the base of the lazerette) for the starboard vent. from this point they are in mid-hull and meander to the starboard battery platform. What other ideas are out there. How to get from outside the hull at the transom to the 'belly' of the boat, bypassing the port lazerette. I'd appreciate any ASAP response. Thanks.
