Re: Could use some advice?
When a good cook opens a restaurant or catering business, they usually go broke. Although it is important to be a boater and know your product and customers, it's more important to know how to watch the bottom line.
This includes product placement: high profit items highly visible. Essential items in the back.* Inventory movement. Watch sale proceed per square foot: fill up 10' with blow-up rafts that don't sell and you are losing money; your business plan shoudl include sales per square foot so you can justify your rent (9% of sales is a good target). Low volume items = high mark-up. Advertise advertise advertise. Know how to work your financing and never ever use your credit card for financing.
Many communities have retired or volunteer businessmen who will consult for free. If not, hire someone, perhaps someone who ran a convenience store. get them to tell you how often your inventories should turn over--the longer it sits, the more you lose.
Watch specialized costs associated with certain products. To sell that $1 hot dog you have to have sanitation, inspection, food license, health classes for employees, bathrooms, etc etc. Your cost per square foot went up. Can you sell enough hot dogs to recoup?
Carrying costs: spare props sound appealing, but you have to carry a wide variety of high-cost items that will just sit there for the odd chance the guy who needs one, needs the one you have: brand, pitch, size, etc. You have to have a huge mark-up to cover the cost of it sitting for 6 months. Maybe go to a prop shop, buy a bunch of used props, and rent them out to the unfortunate?
Cost of goods sold: you have to open early close late. That means two shifts, which is more expensive per hour due to overlap and costs. And most employees either steal from you or let their friends steal.
You have to charge more than Walmart and mail order. Most customers do not understand why (including lots who post on iBoats!). Get them invested in the fact that you are selling convenience/service first and products second.
That's the business side (I happen to have professional experience in retail bankruptcy). Here's some more from the fun side:
Keep a marine radio on for boaters coming back to the dock to get something.
Keep a message board/fishing log both in store and on line for customers to read and post on. That will get people in the store and thinking about you and your being a service business, not just retail.
Buy motor oil in a 55 gallon drum and sell it by the gallon "BYO jug." and bottle the pints and quarts yourself. Lots of people around here do that. You have to time the market on your cost, though.
Cost this out, but it might be a good gimmick: get a big commercial ice maker, and give 5# ice (two big scoops) with every purchase over $5. Or if you can figure out how to secure it, have an ice club: you pay $ per year for up to 2 bags of ice a week. The key is to keep the off-season months, or at least the shoulders, in there so you blend high and low consumption. And never run out of ice!
*"only in America do we make the old and sick walk past the cigarettes and junk food to get to the medicine at the back of a drug store." Think about why that is not an accident.
