Why Aluminum boats?
The best choice for our conditions
Narrowed hull - softer and more frugal gait
The fact that the hull is narrowed means that it is sharper in the middle than on the transom. A less sharp stern gives a boat that is less upright when it is still, but also a more easily driven hull that does not draw as much fuel and also runs faster. That it then becomes sharper immediately and all the way to the bow makes it go softer in high waves. It is unusual to build aluminum boats in this way, as it is much more time consuming and technically challenging than building at the same angle all the way to the foreship. As an example, the UMS 585DC has a bottom angle of 18 degrees on the transom, but the midships has it 24 degrees.
Aluminum
Aluminum is available in a plethora of alloys, all with different strengths and disadvantages. UMS uses only 5083, and always at least 3mm thickness in the hull (4mm from 485 and 5mm from 805). 5083 contains some magnesium. It is thus the strongest of all aluminum alloys that are not heat-treated. Very suitable for marine environments. Some other manufacturers use a poorer alloy with less magnesium, because it can withstand being bent narrower or for cost reasons. UMS instead works around the problem of alternative manufacturing methods. But there is a difference between apples and apples, UMS buys all its aluminum from the Norwegian company Hydro. It guarantees consistent quality for best results!
100% aluminum, 0% organic
UMS chooses to build the interior of their boats completely without wood, it gives a lighter and stronger boat. But above all, longer service life.
Nano - extended gloss
Nanopassivation is an antioxidant treatment made of aluminum that gives extended life and a shine that lasts. Through a chemical process, the metal is bonded with a chemical formula, it becomes a protective layer and appears as glass / clear lacquer-like but is much more durable. This surface treatment takes care of the free ions that otherwise form oxides. Treating an entire boat requires a lot of work and a completely dust-free environment. We have therefore chosen to add nanopassivation as an option.
Reversed chine & frying pans
All UMS hulls have so-called “reversed chine”. This means that at the far end of the hull there is a terminating part that has a "negative" angle. It provides several benefits, including better grip when turning, rejection of splashes from the hull = less wet in the boat and better stability both at speed and when stationary. Step rails are like longitudinal trim tabs that help keep the boat in the right walking position at different loads. Some manufacturers have gone away from step moldings, not UMS. In addition, UMS step strips are not pressed into the aluminum, but are welded. Thus, they are very sharp and help to grip even better in the curves!
Manufacturing technology aluminum boat
All boats from UMS are built in a jig where the individual aluminum plates are mounted before they are welded together. This production technique is more time consuming than the alternatives, but it guarantees that the result will be perfect every time, straight and without tension in the hull. Then all longitudinal and transverse profiles are built up inside the hull. These give the boat an enormous stiffness and strength! Note that all shots are made on the shipyard and of the same aluminum quality. Some other manufacturers use finished profiles of inferior quality. The hull is then filled with floating elements.
Fishing equipment RAM mounts / FASTen
All models, except 865, come as standard with a so-called. C-profile at the top of the inside of the hull. In this profile you can mount holders of various equipment. Everything from rod holder to holder for action camera or net. RAM mounts fit. And we have Borika's rod holder in stock. Check in our webshop . Borika's entire range can be found here .
SunDeck / FishDeck
It is now possible to order a folding throw deck / sun deck for the following models: 485DC 545DC 585DC 655DC 655CC When not in use, it is folded into a cassette and stored in any stowage. Perfect if you want a more versatile boat. Go with the family and swim or go on a sport fishing competition.
