Long-term Debt [Abstract]  
Long-term Debt:
8.      Long-term debt:
Following the execution of the Restructuring Letter Agreements in August 2016 and the related supplemental agreements (the “Supplemental Agreements”), as described below, the Company agreed with all of its lenders to, among others things, defer principal payments owed from June 1, 2016 through June 30, 2018 (the “Deferred Amounts”) to the due date of the balloon installments of each facility. As a consequence no principal payments were required to be made within the twelve months from the year ended December 31, 2016 and therefore no current portion of long term debt was outstanding as of December 31, 2016.
On December 28, 2017 the Company announced that in light of its improved performance and the dry bulk market in general, it is planning to make debt principal repayments that are in total at least equivalent to the amortization payments scheduled prior to the commencement of debt amortization holidays for the first and second quarter 2018, starting from January 1st 2018, under the “cash sweep” mechanism incorporated in its loan agreements as further discussed below. As a consequence, the current portion of long term debt outstanding as of December 31, 2017, as presented in the accompanying balance sheet, has been adjusted accordingly.
