Capacity is the headline split: the Alen 55 carries 16 guests to the Zeelander Z55's 6.
On size, the Zeelander Z55 is the longer boat at 17.00 m LOA to 16.80 m. The Alen 55 is the quicker boat, 35 knots to 32. Range favours the Zeelander Z55, 450 nm against 280 nm. Both run ips.
Net of the spec sheet it is a trade: the Zeelander Z55 is the bigger platform, the Alen 55 the quicker one. Garage envelope and the missions the boat has to cover should settle it.
