try looking at a porta-boat
Porta-Bote Folding Boat Makes Inflatables Obsolete Also Portaboat
as sailingdog suggested
compact .. easy to assemble .. stable .. and cute (well I have a Cal28 flushdeck .. and believe her to be beautiful) ..
also .. if you look around .. you can find one fairly reasonably
paid $400 for mine (with Minn-kota motor) in excellent shape
