Nida Core is a honeycomb coring the material that we chose on the Sabre 52 to give that boat sound levels (I should call them quiet levels) that have rarely before been seen in planing powerboats. That design achieved 75 Db at 25 knots and in that case we are running two CAT C15's at 865 hp each. That's remarkable.
With the Sabre 40 we are hoping for similar results and we are once again counting on Nida Core to produce them. But the 40 has an additional advantage and that is the Zeus drive train. When the boat is idling at rest exhaust gasses will exit through a small diameter by pass. When underway exhaust gasses (and their related noise) exit underwater with the prop wash and this, as we already know from our 42 Express experience, really quietens down the overall build.
Next time you pick up a magazine with a boat review check out noise levels. And remember that the difference between 72 and 80 is about the difference between conversation and a rock concert. It's important for the enjoyment of boating.
