As a business owner, the IRS is more likely to scrutinize your business for payment of expenses that are more of a personal nature. You may reimburse yourself a reasonable amount for the business use of your vessel. Keep careful records of the times used for business and document the business purpose of the trip. You may choose to allocate a percentage of the costs of maintaining and running the boat based on the ratio of business use to total use. Or you can research the cost of a charter boat and reimburse yourself accordingly. Either way, it would not be prudent to pay the repairs or storage through your business.
