Sure. The entry angle is the angle the sides of the bow subtends.  The bigger the angle, the more quickly the water gets pushed aside, which is slower than doing it gradually with a small angle.   The bow on the boat in the video has a fairly fine angle, but it has been chopped off too far before the apex of the triangle and rounded over.  By putting some of the apex back, this would be overcome.  


The spray definitely slows the boat, though I am not sure by how much.  Most of the people I have spoken to who have sailed on the boats kinda like it as it makes the sailing look 'dramatic', without any drama, or actually getting them wet.  As someone to whom efficiency is king, I dislike it and it would be the first thing I altered if I owned one.

Doug,
Living onboard a harry, or any other boat would be cool.   We have come close a couple of times, but the missus has vetoed it on the grounds that she would come home after a hard day's work and find her 'house' out on the briny.   I doubt it would improve the breed.  I leave the interiors to the owners personal preference.

cherry picking the previous long defense post, could you explain some more what you mean by:
"The bow on the video harry is much
blunter than it should be, although the entry angle is quite fine.
Plumbing the bow and filling in the round would eliminate most of the
spray."

Thank you. Luc
