Emma:
You might want to take a look at www.redfishkayak.com, and consider either the Silver which was designed for smaller paddlers, or the Spring Run which has more storage space. You could contact Joe Greenley who designed both boats....he will be able to tell you whether the Silver would have the storage capacity you need.

Joe designs exquisite boats. I am building the Silver for my son/wife (who is your size). The directions are straight forward and Joe responds quickly to email questions.
Good luck...enjoy...and send pics.....Bob
