CUSIP No. Y62159101 13D Page 4 of 11 Pages

Pursuant to Rule 13D-2 promulgated under the Act, this Schedule 13D/A
("Amendment No. 1") amends and restates the Schedule 13D filed on April 26, 2010
(the "Schedule 13D") in its entirety. This Amendment No. 1 is being filed to
attach Exhibit 1, which was previously incorporated by reference to a third
party's Schedule 13D.

Item 1. Security and Issuer.

This statement relates to the ordinary shares, par value $0.0001 per
share (the "Shares"), of Navios Maritime Acquisition Corporation, a Cayman
Islands corporation (the "Company"). The Company's principal executive offices
are located at 85 Akti Miaouli Street, Piraeus, Greece 185 38.

Item 2. Identity and Background.

(a) This Statement is filed by:

(i) Arrowgrass Capital Partners (US) LP ("ACP"), with respect
to the Shares directly held by Arrowgrass Master Fund Ltd., a Cayman Islands
exempted company ("AMF"). ACP serves as the investment manager of AMF; and

(ii) Arrowgrass Capital Services (US) Inc. ("ACS"), which is
the General Partner of ACP, with respect to the Shares beneficially owned by
ACP.

The foregoing persons are hereinafter sometimes collectively referred to as the
"Reporting Persons." Any disclosures herein with respect to persons other than
the Reporting Persons are made on information and belief after making inquiry to
the appropriate party.

(b) The address of the principal business and principal office of ACP and
ACS is 245 Park Avenue, 39th Floor, New York, New York 10167.

(c) The principal business of each of the Reporting Persons is the
management of investment funds and activities related thereto.

(d) None of the Reporting Persons has, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors).

(e) None of the Reporting Persons has, during the last five years, been a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and, as a result of such proceeding, was, or is subject to, a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, Federal or State securities laws or finding
any violation with respect to such laws.

(f) ACP is a Delaware limited partnership. ACS is a Delaware corporation.

Schedule A attached hereto sets forth the information required by Instruction C
of the instructions to Schedule 13D.

Item 3. Source and Amount of Funds and Other Consideration.

The Shares purchased by AMF were acquired with working capital in open market
transactions at an aggregate cost (excluding commissions, if any) of
approximately $30,300,000.

CUSIP No. Y62159101 13D Page 5 of 11 Pages

Item 4. Purpose of the Transaction.

The Shares reported herein by the Reporting Persons were acquired for
investment purposes in the ordinary course of business.

Except as set forth herein or as would occur upon completion of any of
the actions discussed herein, including in any Exhibits hereto, the Reporting
Persons have no present plan or proposal that would relate to or result in any
of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D.

The Company was organized for the purpose of acquiring, through a
merger, capital stock exchange, asset acquisition or other similar business
combination, an operating business (a "Business Combination"). The Company
consummated an initial public offering in July 2008 in connection with which it
raised gross proceeds of approximately $253 million, a significant portion of
which was placed in a trust account pending the consummation of a Business
Combination on or prior to July 1, 2010. Pursuant to certain provisions in the
Company's certificate of incorporation, as amended, a holder of Shares of the
Company issued in the Company's initial public offering may, if it votes against
the Business Combination, demand that the Company redeem its Shares into cash
(the "Conversion Rights"). A Business Combination will not be consummated if the
holders of more than 40% of the Shares vote against the Business Combination and
request Conversion Rights. On April 8, 2010, the Company announced it had
entered into an agreement for a proposed asset purchase which the Company has
determined would meet all of the conditions to the consummation of a business
combination described in the prospectus for its initial public offering (the
"Proposed Business Combination"). On May 4, 2010, the Company announced the
vote on the Proposed Business Combination will take place at the annual meeting
of the shareholders of the Company on May 25, 2010.

On April 14, 2010, AMF entered into an Option Purchase Agreement (the
"Option Agreement") which is referenced as Exhibit 1 hereto with Malibu Capital
Partners, LLC, a California limited liability company ("Malibu"). Pursuant to
the terms of the Option Agreement, AMF granted to Malibu an option to purchase
from AMF all (but not less than all) of the Shares of AMF reported herein. The
option expires on or prior to the earlier to occur of (i) the date the Company
liquidates its trust account or (ii) the unilateral decision of Malibu to
terminate that is communicated to AMF in writing. If Malibu exercises its
Option, AMF is required to sell the Shares to Malibu and Malibu is required to
purchase the Shares from AMF at a price per share equal to that certain pro rata
portion of the Company's trust account per share due to its public stockholders
as set forth in the Company's final definitive proxy statement filed with the
U.S. Securities and Exchange Commission in connection with the Proposed Business
Combination. In the Option Agreement AMF agreed to vote its Shares against the
Proposed Business Combination. Upon exercise of the option by Malibu, AMF agrees
to (i) withdraw and revoke its exercise of Conversion Rights and (ii) vote in
favor of, or abstain from voting upon, the Proposed Business Combination unless
otherwise directed by Malibu.

CUSIP No. Y62159101 13D Page 6 of 11 Pages

The summary of the Option Agreement is not complete, and is qualified
in its entirety by reference to the text of the agreement, which is referenced
as Exhibit 1 to this Schedule 13D. Confidential Treatment is requested with
respect to certain portions of the Option Agreement.***

The entering into the Option Agreement may result in the Reporting
Persons being deemed a "group" with Malibu and certain of its affiliates (the
"Malibu Reporting Persons") within the meaning of Section 13(d) of the Act.
Although the Reporting Persons and the Malibu Reporting Persons may be deemed to
be a "group" with each other within the meaning of Section 13(d) of the Act, the
Reporting Persons do not believe that they are part of a group with the Malibu
Reporting Persons and expressly disclaim membership in any "group" with the
Malibu Reporting Persons. The Reporting Persons expressly disclaim beneficial
ownership of any Shares that may be deemed to be beneficially owned by the
Malibu Reporting Persons. On information and belief, the Malibu Reporting
Persons beneficially own 5,647,250 Shares, representing approximately 17.9% of
the outstanding Shares(the "Malibu Position").

Item 5. Interest in Securities of the Issuer.
