Smooth-running ball bearing blocks are very suitable for all areas where lines have to be pulled through quickly and largely by hand. Examples are the single line reefing system or the deflection of sheets, as well as the lines used to haul and fly the traveller. Especially when there is little wind, trimming becomes much more sensitive. The use of ball bearings is a major advantage, especially on small boats, where most of the lines are run out of hand.
With Sprenger you have the fittings with the best price/performance ratio on the market. In tests conducted by the well-known magazines YACHT and SEGELN, Sprenger blocks were the test winners and achieved the highest scores. The working and breaking loads, the catalogue data in accordance with the actual values and the corrosion resistance were tested. Perhaps you are familiar with the well-known sailor Wilfried Erdmann. He circumnavigated the earth in about 330 days in 1984. About 20 years later he repeated this one-handed circumnavigation, this time even against the prevailing wind directions. He not only used the same boat for both circumnavigations, but for the most part also the same Sprenger blocks. Is there any better proof of the durability and quality of Sprenger fittings? But our fittings are not only popular with circumnavigators around the world. Sprenger products are also very popular with cruising and regatta sailors.
