You’ll need to decide what kind of boats you want to transport. A speedboat for the lake has a very different trailer requirement than a large sailboat with a mast and a keel. Although motorboat transport would likely be a higher-volume business, it’s also something many boat owners can do themselves. But if you keep your prices reasonable and become known for taking extra good care of the boats you transport, you may find people hiring you to take care of this for them anyway. Motorboat owners are likely to have room in their yard to store them, but if you can provide covered storage, you can have an added-value component to your business. You can also add the service of shrink-wrapping the boat before storage.
