Another option would be to purchase the lightest hardshell you can afford. They both have their advantages. A double can be perfect for couples and families. Paddlers of different skill levels and ages can be paired up so that nobody is left behind. It can be a fun family adventure.
Doubles are fast and stable, but lack some of the maneuverability of a single.
Also, purchasing one is a little more risky than buying a single. Make sure that your future paddling partner is as enthused and motivated as you are. A dusty, neglected double hanging in the back of a lonesome garage is not a pretty sight. If you decide on a single, make sure that it has enough storage capacity for whatever stuff you wanna bring along. For most afternoon kayakers, space usually isn t that much of an issue, but if you re going to take long trips, adequate cargo capacity must be available.
