Accounting Policies [Abstract]
Revenue Recognition	We recognize revenue from boat, motor, and trailer sales, and parts and service operations at the time the boat, motor, trailer, or part is delivered to or accepted by the customer or the service is completed. We recognize deferred revenue from service operations and slip and storage services on a straight-line basis over the term of the contract or when service is completed. We recognize commissions earned from a brokerage sale at the time the related brokerage transaction closes. We recognize commissions earned by us for placing notes with financial institutions in connection with customer boat financing when we recognize the related boat sales. We recognize marketing fees earned on credit, life, accident, disability, gap, and hull insurance products sold by third-party insurance companies at the later of customer acceptance of the insurance product as evidenced by contract execution or when the related boat sale is recognized. Pursuant to negotiated agreements with financial and insurance institutions, we are charged back for a portion of these fees should the customer terminate or default on the related finance or insurance contract before it is outstanding for a stipulated minimum period of time. We base the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of June 30, 2014, on our experience with repayments or defaults on the related finance or insurance contracts. We also recognize commissions earned on extended warranty service contracts sold on behalf of third-party insurance companies at the later of customer acceptance of the service contract terms as evidenced by contract execution or recognition of the related boat sale. We are charged back for a portion of these commissions should the customer terminate or default on the service contract prior to its scheduled maturity. We determine the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of June 30, 2014, based upon our experience with terminations or defaults on the service contracts.
Inventories	Inventory costs consist of the amount paid to acquire inventory, net of vendor consideration and purchase discounts, the cost of equipment added, reconditioning costs, and transportation costs relating to acquiring inventory for sale. We state new and used boat, motor, and trailer inventories at the lower of cost, determined on a specific-identification basis, or market. We state parts and accessories at the lower of cost, determined on an average cost basis, or market. We utilize our historical experience, the aging of the inventories, and our consideration of current market trends as the basis for determining a lower of cost or market valuation allowance. As of September 30, 2013 and June 30, 2014, our lower of cost or market valuation allowance for new and used boat, motor, and trailer inventories was $1.8 million and $2.4 million, respectively. If events occur and market conditions change, causing the fair value to fall below carrying value, the lower of cost or market valuation allowance could increase.
Property Plant and Equipment Impairment or Disposal of Long Lived Assets	FASB Accounting Standards Codification 360-10-40, “Property, Plant, and Equipment - Impairment or Disposal of Long-Lived Assets” (“ASC 360-10-40”), requires that long-lived assets, such as property and equipment and purchased intangibles subject to amortization, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to undiscounted future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair market value. Estimates of expected future cash flows represent our best estimate based on currently available information and reasonable and supportable assumptions. Any impairment recognized in accordance with ASC 360-10-40 is permanent and may not be restored. Based upon our most recent analysis, we believe no impairment of long-lived assets existed at June 30, 2014.
Income Taxes	We account for income taxes in accordance with FASB Accounting Standards Codification 740, “Income Taxes” (“ASC 740”). Under ASC 740, we recognize deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which we expect those temporary differences to be recovered or settled. We record valuation allowances to reduce our deferred tax assets to the amount expected to be realized by considering all available positive and negative evidence. Pursuant to ASC 740, we must consider all positive and negative evidence regarding the realization of deferred tax assets, including past operating results and future sources of taxable income and tax planning strategies. Based on the available evidence, under the provisions of ASC 740-10, we determined that our net deferred tax assets needed a full valuation allowance as of September 30, 2013 and June 30, 2014.
Stock Compensation	We account for our stock-based compensation plans following the provisions of FASB Accounting Standards Codification 718, “Compensation — Stock Compensation” (“ASC 718”). In accordance with ASC 718, we use the Black-Scholes valuation model for valuing all stock-based compensation and shares purchased under our Employee Stock Purchase Plan. We measure compensation for restricted stock awards and restricted stock units at fair value on the grant date based on the number of shares expected to vest and the quoted market price of our common stock. For restricted stock units with market conditions, we utilize a Monte Carlo simulation embedded in a lattice model to determine the fair value. We recognize compensation cost for all awards in operations, net of estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award.
Fair Value of Financial Instruments	The carrying amounts of our financial instruments reported on the balance sheet at June 30, 2014 approximated fair value due either to length to maturity or existence of variable interest rates, which approximate prevailing market rates
Use of Estimates	The preparation of unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. The estimates made by us in the accompanying unaudited condensed consolidated financial statements include valuation allowances, valuation of goodwill and intangible assets, valuation of long-lived assets, and valuation of accruals. Actual results could differ from those estimates.
Consolidation	The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries, all of which are wholly owned. All significant intercompany transactions and accounts have been eliminated.

Inventories

Inventory costs consist of the amount paid to acquire inventory, net of vendor consideration and purchase discounts, the cost of equipment added, reconditioning costs, and transportation costs relating to acquiring inventory for sale. We state new and used boat, motor, and trailer inventories at the lower of cost, determined on a specific-identification basis, or market.

Based on the available evidence, under the provisions of ASC 740-10, we determined that our net deferred tax assets needed a full valuation allowance as of September 30, 2013 and June 30, 2014.

Stock Compensation

We account for our stock-based compensation plans following the provisions of FASB Accounting Standards Codification 718, “Compensation — Stock Compensation” (“ASC 718”). In accordance with ASC 718, we use the Black-Scholes valuation model for valuing all stock-based compensation and shares purchased under our Employee Stock Purchase Plan.

We recognize compensation cost for all awards in operations, net of estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award.

Fair Value of Financial Instruments

The carrying amounts of our financial instruments reported on the balance sheet at June 30, 2014 approximated fair value due either to length to maturity or existence of variable interest rates, which approximate prevailing market rates

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. The estimates made by us in the accompanying unaudited condensed consolidated financial statements include valuation allowances, valuation of goodwill and intangible assets, valuation of long-lived assets, and valuation of accruals. Actual results could differ from those estimates.

Consolidation

The unaudited condensed consolidated financial statements include our accounts and the accounts of our subsidiaries, all of which are wholly owned. All significant intercompany transactions and accounts have been eliminated.

- Definition

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
