help needed for a design project!

[UnReason]

im a transportation design student currently in my 1st year.
i have a project on sailboat conceptualisation....

Here is the brief on which my sail boat has to be made:

Usage - should be sailed both in lakes and sea, basically for cruising purpose.
Length - approx 14 -16 feet.
Draft - 4-5 Feet max with keel fully down
Sails - Main and Jib
Body - Fiberglass / sandwiched foam, double bottomed construction
Weight - as light as possible for easy portability
Rigging - As simple as possible
Mast - Aluminum (suitably strengthened)

Problem is, i have never been sailing, and almost know nothing bout sailboats except the stuff i hav found online. i would like to hear the views an advice from enthusiasts themselves. whatever may seem useful for this project.
Il be thankful for whatever help i can get

another thing i need to know is the bestselling sailboats in the size i have mentioned above...

thank you again.
