Re: Sailing alone??
If your spouse is not a 'keen' sailor then small, light, tender boats like 15 foot dinghies and lightweight trailer sailers may not be the right type. Something more sedate like a Catalina 27, Ranger 26/29 or newer boats of that size and type may suit better. These can easily be sailed solo if properly set up.
As boats get larger the biggest hurdle to singlehanding is usually the docking/undocking routines, esp if breezy or strong tidal current conditions persist in the marina. Kinda like flying.. the takeoffs and landings can be the tricky bits most days.
