A 19′ (5.8m) express cruiser
This is the 3-D concept drawing and design profile featured in Design Sketchbook in WB No. 270, September/October 2019.
PENNY’s warped hull shape has deep-V sections forward and flatter ones aft, but for the sake of comfort and speed she is deeper than her predecessor about one third of the way aft of the bow.
- LOA: 19′ (5.80 m)
- LWL: 17′11″ (5.47m)
- Beam: 6″4″ (1.93m)
- Draft: 11″ (0.28m)
- Displacement: Salt water, half-load 1,808 lbs (820kg), Light vessel approx 1,100 lbs (499kg)
- Prismatic coefficient: 0.68
- D/L ratio 140
- Outboard 50-hp four-stroke gas
The curving hard dodger matches the hull’s retro styling. The bow line and anchor may be handled from the safety of the forward cabin hatch.
The transition of a flared bow to a tumblehome transom requires careful design to avoid hard spots; a gradual blending of highlights and shadows indicates a fair hull.
