the time is now. =) Buying to a price point. =(
I guess you can skip the rest of the list as well - none of the other boats mentioned will have a retractable sprit. A sprite is a late-90''s innovations showing on sport boats and some performance cruisers like J-Boats, and you will need to quadruple your budget to get into that field.
I''ve seen stories about installing deck mounted sprites if you need to go that way, although a symmetrical spinnaker on a 30 footer isn''t very big and can be reasonably set up to singlehand. Maybe you should go though your list of criteria and break them into gotta-haves and nice-to-haves. If you list your gotta-haves, perhaps someone can tell you whether such a boat exists at any price.
