Changes in Accounting Estimate [Abstract]
Changes in Accounting Estimate	Note 7. Changes in Accounting Estimate Based on company policy, we review the reasonableness of our salvage values for our fleet every three years based on the most recent three year average price of scrap steel per metric ton. In the first quarter of 2012 we reviewed and adjusted the salvage values on eight of our vessels, based on material change in the market value of scrap steel. The adjustments resulted in increasing the salvage values and reducing our depreciation expense on these eight vessels by approximately $3.8 million annually. This adjustment increased both our pre-tax and net income by $1,890,000, or $0.26 per share, for the six months ended June 30, 2012. Due to the company being in a valuation allowance position there was no impact on income taxes.
