Exhibit 1

Nordic American Tanker Shipping Ltd. (the Company) - (NYSE:NAT) Letter to
Shareholders from the Chairman & CEO

Hamilton, Bermuda, March 20, 2006

Dear Shareholder,

I would like to report to you on the development of our Company since the New
Year - again an active period.

The spot tanker market during the first months of 2006 has been strong. Seven of
our eight vessels are currently employed in the spot market. The average spot
market rate, according to the spot assessment of the Imarex Tanker Index which
gives an indication of the level of the spot market, was $50,988 per day for the
two first months of 2006. As of March 17, the average spot market rate for March
is $38,472 per day according to the Imarex Tanker Index. Broadly speaking, the
tanker market exhibits tight vessel supply, leaving the market finely tuned with
high capacity utilisation. While it is expected that short term spot rates may
vary significantly and continue to be volatile, in our view the supply and
demand tanker market fundamentals are positive.

Our dividend and earnings release related to the first quarter 2006 will be
announced on May 2nd at which time we expect to announce solid earnings and

We passed an important milestone on February 27th when we announced that we had
agreed to acquire a double hull Suezmax vessel, built in Korea in 1998, at a
price of approximately $69 million. This vessel is expected to be delivered from
the seller to the Company in early April, increasing the NAT fleet to nine
vessels with an aggregate capacity of 1,384,491 dwt.

On the same date NAT commenced a follow-on offering which successfully closed on
March 14th 2006. The Manager of NAT, Scandic American Shipping Ltd., which I
control, purchased 100,000 shares in the follow-on offering at the same price as
the other investors.

These two events, together with our plans to acquire a tenth vessel later this
year, are a demonstration of the Company's policy of accretive growth. For us,
accretive growth is to increase our cargo carrying capacity per share. To put it
differently, accretive growth means that the Company produces higher earnings
and pays higher dividends per share after an acquisition than if the acquisition
had not taken place.

Over the last 15 months, having increased the fleet from 3 vessels to 9 vessels,
we have effectively managed our growth. We were able to pay a record dividend
per share for the 4th quarter of 2005 ($1.88 per share) as compared to the 4th
quarter of 2004 ($1.62 per share), despite a material decrease in spot rates for
the 4th quarter of 2005 as compared to the 4th quarter of 2004.

We currently estimate that our cash breakeven is $8,500 per day. The break even
rate is the amount of average daily revenues for our vessels which will cover
our cash, general administrative expenses, voyage expenses, if any, vessel
operating expenses, interest expenses and other financial charges. Based on
publicly available information, this is among the lowest levels in the industry
for Suezmax tankers.

Our aim is to continue to operate a modern and environmentally friendly fleet,
focusing on double hull vessels only.

Our policy is to declare quarterly dividends to shareholders, substantially
equal to our net operating cash flow during the previous quarter.

Since 1998, the first full year after NAT became stock listed, the arithmetic
average cash yield per annum from our dividends has been approximately 14.7% and
has not been less than 10% in any year. This is the annual average actual
dividend paid to shareholders in relation to the average daily stock price
during each year. Our Company has now paid dividend for 33 consecutive quarters.

In NAT's earlier phases of the development, the Company was financed solely with
equity. We have adjusted that policy slightly, as earlier advised you. Our
policy is now to maintain in the region of $15 million per vessel in current
market conditions. Our balance sheet is one of the strongest in the industry.

It is very important, impacting the supply of tonnage, that two major oil
companies have recently adopted a policy of no longer chartering single hull

When it comes to the demand side, longer term prospects for the tanker market
depend, above all, upon developments at the macro economic level. It is
comforting to see that growth in the United States and in emerging economies
seems to continue, resulting in increased oil consumption and transportation

In summary, I would like to stress that the main objective of our Company
continues to be value creation via a transparent, predictable and clear
strategic platform based on a unique operating model. Our company is in a good
position for further growth and progress.

We are overwhelmed by the support the shareholders are showing NAT. Through
approaches and written communication to us, shareholders express views and make
comments on our activities. We encourage such active involvement from our

Matters discussed in this press release may constitute forward-looking
statements. The Private Securities Litigation Reform Act of 1995 provides safe
harbor protections for forward-looking statements in order to encourage
companies to provide prospective information about their business.
Forward-looking statements include statements concerning plans, objectives,
goals, strategies, future events or performance, and underlying assumptions and
other statements, which are other than statements of historical facts.

The Company desires to take advantage of the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995 and is including this
cautionary statement in connection with this safe harbor legislation. The words
"believe," "anticipate," "intend," "estimate," "forecast," "project," "plan,"
"potential," "will," "may," "should," "expect," "pending" and similar
expressions identify forward-looking statements.

The forward-looking statements in this press release are based upon various
assumptions, many of which are based, in turn, upon further assumptions,
including without limitation, our management's examination of historical
operating trends, data contained in our records and other data available from
third parties. Although we believe that these assumptions were reasonable when
made, because these assumptions are inherently subject to significant
uncertainties and contingencies which are difficult or impossible to predict and
are beyond our control, we cannot assure you that we will achieve or accomplish
these expectations, beliefs or projections. We undertake no obligation to update
any forward-looking statement, whether as a result of new information, future
events or otherwise.

Important factors that, in our view, could cause actual results to differ
materially from those discussed in the forward-looking statements include the
strength of world economies and currencies, general market conditions, including
fluctuations in charter rates and vessel values, changes in demand in the tanker
market, as a result of changes in OPEC's petroleum production levels and world
wide oil consumption and storage, changes in our operating expenses, including
bunker prices, drydocking and insurance costs, the market for our vessels,
availability of financing and refinancing, changes in governmental rules and
regulations or actions taken by regulatory authorities, potential liability from
pending or future litigation, general domestic and international political
conditions, potential disruption of shipping routes due to accidents or
political events, vessels breakdowns and instances of off-hire, failure on the
part of a seller to complete a sale to us and other important factors described
from time to time in the reports filed by the Company with the Securities and
Exchange Commission, including the prospectus and related prospectus supplement,
