Our friend at NavyRecognition offers this video of the CMN Ocean Eagle 43 prototype built for the Navy of Mozambique, in sea trials in what are reported to be State 5 seas.
There is no displacement listed, but, except in beam, this vessel is notably smaller than the Webber class WPCs (143 ft vs 154 for the Webber class). It has a smaller crew (7) and accommodations (15), but otherwise appears to have similar capabilities with a speed of 30 knots, a range of 3000 miles at 20 knots, and a 7 meter RHIB in a ramp at the stern.
They also advertise a proposed mine hunter version that is more limited in speed and dispenses with the small UAS flight deck in favor of unmanned underwater vehicles for mine hunting and destruction. Assuming the same hull is used, the dimensions for both are 43.6 meter in length, 15.7 meter beam, and two meter draft.
When it comes time to replace the 87 footers, perhaps we should consider something similar, though dealing with the much greater beam might be a bit of a challenge in some places.
