Capacity is the headline split: the Alen 55 carries 16 guests to the Ribbon R45XC MK2's 12.
On size, the Alen 55 is the longer boat at 16.80 m LOA to 13.48 m. The Ribbon R45XC MK2 is the quicker boat, 40 knots to 35. Drivetrains differ: the Alen 55 runs ips, the Ribbon R45XC MK2 sterndrive.
Net of the spec sheet it is a trade: the Alen 55 is the bigger, higher-capacity platform, the Ribbon R45XC MK2 the quicker one. Garage envelope and the missions the boat has to cover should settle it.
