Ums 500 - high-speed boat calculated for usage with the engine up to 70 h.p. Due to unique structural performances is fitted to the strickt conditions of operation. Ums 480 is intended for the
wreckers, aquatic(water) militia and other services, fishers, hunters, people leading the active lifestyle. In the project the providing of more spacious steering well is taken into account also.
The control console divides a steering well into two parts. In a stern the sofa - kit locker is placed. In a fore part there is a locker, in which it is possible to arrange equipment. Paying

Large height and breadth of a side in a bow ensures good lifting on a wave. The boat can confidently be maintained at a wind 4-5 balls and wave of height 0,5-1,0 m. To get from water on a boat it
is more convenient from a stern. The boat consists of a purely aluminium hull, advanced internal set, glass-fiber section of a deck. Width of the plating from an aluminium alloy, noncorroding in
seawater is 3,0 mms. On a stern platform it is possible to establish a folding stairway, additional transom for an outboard engine of low power, 5-15 h.p. Under a stern sofa the accumulator, fuel
bowl of capacity 70 l, backup fuel bowl on 25 l is located.In a steering well is placed:
