I saw a wherry on craiglist and couldn't resist. I knew it needed some TLC but surely that would be less work than a kit from scratch (ha!). So... it was built by a first-timer who did a pretty good job but as I look at it closely it seems to be not just overweight but possibly a bit rotund. So I'm wondering what are the dimensions of a proper wherry single. Could anyone out there tell me the 'inside width (between top strakes across the interior) at 

1. The forward bulkhead
2. Center of  forward seat plank
3. Ditto aft seat
4. Rear bulkhead
5. Angle of strakes where they're brouight together at the bow?

Thanks!
