A hull for a high speed motor boat has a bow section of V-form having a hard stem (6) which merges into a keel (7). The keel is divided amidships into two hard keel after-sections (8, 9) which diverge in the sternward direction and between which is provided, on the underside of the hull, a tunnel (10) which is open at the stern and extends forwardly while tapering inwardly. The forward end of said tunnel may be determined by a bulkhead (11) at the after end of the forward hard keel section (7), and the tunnel may be vented to atmosphere through the hull, for example through the bulkhead (11). |
