Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 9.8 ft one-way run is a stated reference, not a universal installation prescription.
