Capacity is the headline split: the Novamarine BS200 AD carries 30 guests to the Alen 55's 16.
On size, the Novamarine BS200 AD is the longer boat at 20.10 m LOA to 16.80 m. The Novamarine BS200 AD is the quicker boat, 48 knots to 35. Drivetrains differ: the Alen 55 runs ips, the Novamarine BS200 AD outboard.
On the numbers the Novamarine BS200 AD is the bigger, higher-capacity boat, the pick when guest volume leads the brief; the Alen 55 is the tighter, simpler option. The brief, not the badge, should decide.
