[hpv-boats] Basic Boat Shape

[flareking at talktalk.net]

This is intended for Rick, whom with his vast computor design knowledge can clarify this design query.
I am considering building from 4 mm ply, a hard chined mono-hull similar to the V14.
My question concerns the stern, should this be pointed in plan view like the V14 or cut square and maintaining the width of the boat.
This is shown on site www.trimalite.eu 2008 photos or Mike Lampi's Cadence.
The boat project is intended for distances of 8 km or more & I am not interested in the absolute top speed for 100 m sprints.
