The Dyna-Ski 20' Closed Bow boat is a much refined and improved version of the original Hydrodyne 20' Closed Bow Boats designed in the early 1980's and built for many years. The new style Dyna-Ski has taller sides and is longer. Dyna-Ski 20' Closed Bow boats are all built the same so the boats are all built and designed to be anything from a single to a triple over the lifetime of the boat right from the start. There are differences between the Dyna-Ski boats as they are initially rigged but this model can have its configuration changed with minimal rework of the boat hull. So a single Dyna-Ski 20' Closed Bow can be changed into a twin or even a triple motored boat without changes to the hull other than holes to mount the motors. The rigging for the motors and steering of singles, twins and triples will likely be completely different though.

This modern revision of the old tried and true Hydrodyne Outboard closed bow boat features an additional 9" of hull length which means the boat has more load capacity. (about 5%). The single, twin and triple motored applications float noticeably higher in the water than the older style boats.  A low rider triple motored boat is not good!  The driver and passengers also sit about 18" further forward in this boat compared to the older style of boats so the driver can see better and less weight is needed in the nose of the boat. All our boats have higher sides than the older boats for a dryer ride. The additional length also means the Dyna-Ski boat does not squat as much with bigger twin and triple applications. This special purpose model has a lot of additional material in the areas that need it for this type of usage.  The stringers and floor is fully encapsulated unlike the older style of boats.

The Dyna-Ski 20' closed bow outboard standard features include: 3+" transom, 72" motor mounting area, single color gel coat, an adjustable throttle pod. driver's bucket seat, rear facing passenger bench seat, passenger foot brace, 2 7/8" rear mounted ski pylon, 40+ gallon front fuel tank with one, two or three fuel pickups, pre run motor fuel lines, plug in running lights, pop up mooring cleats, heavy duty bow and stern eyes, carpeted floor, rub rail, bilge pump and flotation. A windshield is available on these models.

We strongly suggest if you want a entertainment system in your boat that you buy it locally so you have someone local to service the unit. Customers desires vary so widely it is nearly impossible to list all the stuff people have installed in their boats.
