Range is where they part: the Alen 55 covers 280 nm to the Riva Capri 58's 200.
On size, the Riva Capri 58 is the longer boat at 17.27 m LOA to 16.80 m. It also takes more guests, 16 against 14 on the Riva Capri 58. The Riva Capri 58 is the quicker boat, 37 knots to 35. Drivetrains differ: the Alen 55 runs ips, the Riva Capri 58 shaft.
These two are closely matched; the decision comes down to the specific brief, garage envelope, guest count, and the missions the boat has to cover. The table below lays out every spec side by side.
