Straight Line Depreciation. Find the cost of the boat, estimate the useful life of the boat and estimate how much the boat is worth at the end of the useful life. For example, a boat costs $50,000. The company estimates they will use the boat for 20 years and sell the boat for $10,000 at the end of the 20 years.he current value of the boat equals the cost of the boat minus the accumulated depreciation on the boat. In the example, $50,000 times 0.075 equals $3,750. For the next year, you would subtract $3,750 from $50,000 to find the new current value of the boat.
