I too have been thinking about my cruiser fleet.
I have decided on three options.
1) A 170m long version of the below design. This fits most dock facilities I have but has poor seakeeping and to save space I won't post the SS report just yet.
2) A light but fast cruiser with 4x3 190mm and 120mm belt and 32kts speed. A longer hull, since most CA have hulls around 185m+ this design follows the trend and is bigger. Facilities can allways be upgraded later.
