Size and Weight
Be careful with full drop-stitch kayaks – they tend to be heavy! There’s really no way around this because the amount of PVC and other material required to make a robust chamber, it all ads up.
Make sure you check the weight so you know if you’ll be able to lift it. A lot of kayak sellers online give you the weight of the kayak only, not including seat, fin & foot rest.
If you are planning on a tandem it's also really worth asking whether 2 solo kayaks would be a better fit for you. Tandems are great if you are always going tandem, or if you are paddling with small kids.
A lot of the tandem kayaks are marketed as also suitable for going solo, but it’s quite hard work carrying and setting up a heavy tandem kayak.
It might cost more in the short term to get 2 solos, but we have so many customers who have purchased a tandem and then come back for a solo, it ends up costing more in the long run.
