The following constitutes Amendment No. 2 to the Schedule 13D filed by the undersigned (“Amendment No. 2”). This Amendment No. 2 amends the Schedule 13D as specifically set forth herein.

Item 3 is hereby amended to add the following:

The aggregate purchase price of the 32,600 Shares acquired by RC GLF since the Business Combination is approximately $1,146,446, including brokerage commissions. Such Shares were acquired with the working capital of RC GLF.

Item 4 is hereby amended to add the following:

On May 6, 2019, Raging Capital delivered a letter to the Chairman of the Board of Directors of the Issuer (the “Board”) providing feedback on the Issuer’s business, operations, strategy, governance and executive compensation. While Raging Capital commended the Issuer for its leading quality, scale and young age of its global fleet and its best-in-industry balance sheet, Raging Capital also expressed a number of concerns that it believes the Board must urgently address so that the Issuer can capitalize on its enormous opportunities. Specifically, Raging Capital noted concerns about the Issuer’s historic reputation as slow moving and bureaucratic, high G&A costs per vessel, inefficiency of the current balance sheet structure, unwieldy board size, the Board’s lack of material ownership of the Issuer and the absence of a clear, incisive and focused short and long-term strategy. Raging Capital urged the Board to honestly evaluate the state-of-affairs at the Issuer and to immediately tackle the challenges faced by the Issuer. The foregoing description of the letter is qualified in its entirety by reference to the letter, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Items 5(a)-(c) are hereby amended and restated to read as follows:

(a)       The aggregate percentage of Shares reported owned by each person named herein is based upon 37,289,713 Shares outstanding as of March 6, 2019, which is the total number of Shares outstanding as reported in the Issuer’s Schedule 14A filed with the Securities and Exchange Commission on March 18, 2019.

As of the close of business on May 3, 2019, each of Raging Capital and William C. Martin may be deemed to beneficially own 2,616,954 Shares, consisting of (i) 2,452,065 Shares held directly by RC GLF, (ii) 65,792 Shares underlying Warrants held directly by Raging Capital Offshore Fund and (iii) 99,097 Shares underlying Warrants held directly by Raging Capital Fund QP, by virtue of their relationships with RC GLF and the Raging Funds discussed in further detail in Item 2 of Schedule 13D, constituting approximately 7.0% of the Shares outstanding.

As of the close of business on May 3, 2019, William C. Martin may be deemed to beneficially own an additional 59 Shares and 644 Shares underlying Warrants held directly by him, which, together with the 2,452,065 Shares and 164,889 Shares underlying Warrants held directly by RC GLF and the Raging Funds that he may also be deemed to beneficially own, constitute approximately 7.0% of the Shares outstanding.

Each of the Reporting Persons, as a member of a “group” with the other Reporting Persons for purposes of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may be deemed to beneficially own the securities of the Issuer owned by the other Reporting Persons. The filing of this Schedule 13D shall not be deemed an admission that the Reporting Persons are, for purposes of Section 13(d) of the Exchange Act, the beneficial owners of any securities of the Issuer he or it does not directly own. Each of the Reporting Persons specifically disclaims beneficial ownership of the securities of the Issuer reported herein that he or it does not directly own. Without limiting the foregoing sentence, each of RC GLF and the Raging Funds specifically disclaims beneficial ownership of the securities of the Issuer held by it by virtue of its inability to vote or dispose of such securities as a result of the LPA or IMA, as applicable.

(b)       Raging Capital and William C. Martin may be deemed to share the power to vote and dispose of the Shares held by RC GLF and the Raging Funds.

William C. Martin has the sole power to vote and dispose of the Shares he directly owns.

(c)       Schedule B annexed hereto lists all transactions in the Shares during the past 60 days by the Reporting Persons. All of such transactions were effected in the open market.

Item 7 is hereby amended to add the following exhibit:
