Range is where they part: the Delta Delta covers 450 nm to the Alen 55's 280.
On size, the Delta Delta is the longer boat at 18.22 m LOA to 16.80 m. It also takes more guests, 20 against 16 on the Alen 55. The Delta Delta is the quicker boat, 38 knots to 35. Both run ips.
On the numbers the Delta Delta 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.
