From what you've said, you have no expenses and the owner or the business has all of them. ( slip or mooring
and beverage, repairs
etc. ) Then there's taxes
tax, sales tax, SS tax etc. ( if you plan on paying those). Then there's depreciation.
My question to you would be: how long are you willing to work without being paid? You won't know how much money
the business earns until all the expenses are factored in. There's a break-even point to the business. You will have to take charters out for free until the break-even point is achieved. The BE point is a function of the fixed and variable expenses vs sales.
You can try to break it down on a per charter
basis, by attempting to amortize the expenses over the season but in the 1st year you'll have no sales history
into the budget
, and there's always unforseen expenses. ( someone drops a winch
, or breaks something.)
Your post didn't mention slip or mooring fees
. Personally, I wouldn't put my vessel into charter service
unless I could deduct them from the business, the IRS will look at % of sales. (The amount of charters vs personal use)
Perhaps, I've made this more complicated that it is. If it were me, I'd decide what my time was worth for a day, and make sure the fees
supported that and I got paid for every trip, factor your fee in as an expense to the business. What is the owner getting? The write-off of Slip fees? ...
I don't think there's a simple percentage answer one can give, with the limited information given. There are many ways to organize.
