You love your fishing boat, what with all the joy it's provided for you over all these years, but now you're thinking about getting something new. It isn't that the boat is damaged in some way. You're just looking for something more modern, something that will have those features you would have had the factory fit for you if it had not been so darn expensive. Your own rig would be a good used boat buy for anyone, but there are others out there with features you wanted for your own and the prices are about what you want for your boat. How can you compete?
Start where you should have started earlier: customize your boat so that it is just as good as that boat you saw for sale on the harbor just last week or so. If you can get used parts, the parts your boat is missing, parts about the age of your boat so that it fits just right, adding those features now might just make that used boat even more valuable then the one your saw.
You can do most of the customizing yourself. You can do certain things that might even surpass what's out there. For instance, you could remove that built-in battery, heavy as it is, and replace it with a portable charger. It's an easy job. You might have to move a few wires around, but that's nothing. That battery is at least thirty pounds, you know. When you give your prospective customer a cruise, they'll notice how light it feels in comparison to that competitor of yours down the walk.
Move things around if you want your used boat to accommodate your prospective buyer better than it did you. Just removing a large batter and replacing it with a charger will open up the bilge. In some model, it'll make the water pump accessible to. If you've got compartments that would have been better somewhere else, it's no big job to move them.
Now wiring might be more complicated, but you can also lighten the boat's weight Simplify your circuits if you know how. You'll be able to remove pounds. Some wiring may have chafed. A few strips, and that's fixed.
You can do other things to make that used boat attractive. If you lengthen ropes in certain places, you could be reducing strain when used. For instance, lengthen the retract rope of your trolling motor. You can strengthen them with epoxy and heat shrink tubbing. Speaking of the trolling motor, a spare motor, if you have done, could be encased in a custom build locker so that in rough seas damage is prevented.
Don't hesitate to put new carpet down, nor at least newer than what you've got in it now. You can carpet your storage area and your rod locker. Now its a more protective space for what ever may be stored.
You might add other features to your used boat that the one down the dock doesn't even have, but be sure you're not spending too much to make that boat appealing. If you do, you might find that boat is such a deficient thing after all.
