Our Products

Olsson Mfg. pioneered the original transom fork design some 25 years ago. Since the original, we have worked to provide vessel owners many options.
We believe you shouldn't sacrifice your vessel's performance to take along your tender. Nor should you need to stow your tender items in your valuable vessel space.


What is the cost of a Davit?


Most people think of the cost of a davit as being the purchase and installation price. We argue that it is more than that. We think of costs in two ways:

1. How does it change the performance of the vessel?

No one in their right mind would drag a parachute behind their vessel everywhere they went. Why? It creates drag which then requires more power to maintain the same speed or a reduction in speed at the same power. More power means more fuel. Less speed means more time running. What does this cost you? How much is a gallon of fuel?

Many davits on many vessels are exactly the same as dragging a parachute everywhere you run. Any time you interrupt the clean lines or laminar flow of you vessel, you increase drag and decrease performance. In certain marginal performing boats, it could be the difference of getting on plane or not. That certainly changes the performance. What if a davit system where to create just enough of a low pressure that it decreases the performance by 2%. Not much. But at $4.00 per gallon that’s $.08. You’re still paying for that davit $.08 per gallon of fuel for the life of the davit.

If you own an express style boat, a convertible, a sedan, sport fisher or down-easter, any aft edge riding davit system you buy will drastically effect your performance. If you have and aft cabin, an argument could be made, but you must still consider the low pressure. Exhaust?

At Olsson Mfg., our davits “cup” little if any air. No drag chute. No low pressure. No exhaust soot across the transom and swim step. Laminar air moves above, below and around our davit/dinghy combo virtually eliminating any performance robbing drag chute effect.


2. If every time you stow you tender on your davit, you are forced to unload the tender, is it costing you space?

If you have to find storage for the motor, battery, fuel, fishing gear, crab or shrimp pots, is it robbing you of vital space that you could use to bring other things. Costco provisions versus fuel dock provisions. Extra safety items versus tender supplies? Olsson Mfg feels tender items belong in the tender. Our systems allow the motor and fuel to stay where the manufacturer intended. With the addition of a cover, all items stowed in the tender stay high and dry. Instead of robbing storage, a transom davit is adding storage.

So when considering a davit purchase, add to you vessel don’t take from it.
