I've embarked on a cedar stip Melonseed. The Barto plans I have call for ribs - but the plans contemplate the glued lapstrake construction method. Its a 14 foot vessel, a little over four foot beam, shallow hull - and the cedar strips will be sandwiched between fiberglass and epoxy. Do you all think I still need ribs? I wrote to Barto - but no response. Thanks all.
