I am a little sceptical about the new shipping IPOs, because to me the most important thing is the management of a company. I know nothing about the managers of these new companies, and would like to follow their doings for some time before buying in.
Safe Bulker (SB $18.85 now, IPO price 19.00), an IPO a couple of weeks ago, seems to be a good company with a modern fleet and trustfull charterers, but still - I would follow their actions a couple of quarters before buying their shares.
Read the IPO documents of the Brittania Bulk very carefully and Google all the possible information about them before making a buy decision.
