I wanted to see if anyone had experience with wide stub keels - sailing, beaching mooring,.. general stuff. I noted a comment on the William & John Atkin website: "I have attempted to solve the headroom problem in a small boat by combining the excellent underwater form of the Sea Bright skiff.." ie a wide stub keel.
Anyway I've been doing a design for a trailerable (just) cutter with standing headroom, achieved the same - by making the stub keel wide. Width of bottom of keel 0.42m (16.5"), internal floor width approx 0.5m (1' 8") plus the angled internal hull both sides (3' between seats) - draft min 0.7m (2' 3.5").
Other specs if needed are... Lod 8.1m (26.5') , Lwl 6.77m (22.2' ), Loa 10.7m (33') , Beam 2.43m (8') , Displ light 2500kg (5500lb) , Pris.C. 0.55 with Design displ 2990kg (6590lb) , D/L 268 , Seat headroom 0.91 (36") , Standing headroom mid floor 1.82 (6') , ballast ratio approx 35%, simple static stability calcs appear to come out about 140 deg (preliminary), centreboard through lead ballast keel - the counterstern allows for a slightly bigger cockpit without the extra displacement of increased Lwl.
And here's a bit of a picture..
Thanks for any comments
