Christos Papanicolaou was pushing an initial public offering for a company called Universal Maritime nearly a decade ago and got a frank opinion from one banker.

That was David Herman, head of maritime investment banking for Credit Suisse in New York for a dozen years.

Despite Papanicolaou’s persist­ent efforts, the IPO failed in 2012.

“I think I may have been the only banker on Wall Street who told him I didn’t think the deal could get done,” Herman recalled.
