CPT SST vs Howmar 12: the short version
- The CPT SST and Howmar 12 are close in length (12.2 ft3.72 m vs 12.2 ft3.71 m ).
- The Howmar 12 is heavier, displacing about 430% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the CPT SST rates better for offshore work (2.87 vs 3.58).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
