Nash - you are correct that it could not haul large cargo. But, I believe there is already infrastructure in place for that. Ferry express wasn't doing truck or cargo; they didn't even have a dock. I also doubt Ferry Express did a lot of passenger business since their cost was not significantly less than a flight (Correction/edit: Copa wants $600 Pamana City to Cartegena) . The service would need to cater to overlanders, car, bikes and cheapskates. How much "adventurer" traffic is there across the Darian Gap? There is more than the Stahlratte can keep up with - every crossing is booked months in advance. I see a lot of RRs here and on other sites, but there must be many more of which we're unaware. I'm neither a businessman nor a boat captain, but I can't help to think a right-sized ferry could be a profitable business opportunity.
