Take a look at Chris Downey's boat on
www.classicseacraft.com's home page under 23' boats. He lives on the south shore here in MA and is not hard to get a hold of on the phone. He can probably give you some insight into the "bow heavy" questions. His hardtop is as nice as any I have seen.
I have also been thinking about the same thing, though I'm also thinking about an arch /soft top combination to maintain the option to "let the sunshine in" on some of the nice days.
(If you can't locate a phone number, let me know by PM.)
