Looking to sell my 18' dyne. Originally a Bartlett boat from the 70's. Original hull core and transom. Rebuilt in the 90's including new PVC foam floor and stringers, gelcoat, imron accent colors, rub rail, Mastercraft pylon, carpet, etc. Flat floor straight to the forward deck. Custom rear facing passenger seat and Prostar drivers seat. Battery in front 6 gallon cans in the back. 18 gallon tank could be re-installed in front. With a serviceable shorelander single axle trailer and custom cover. This is possibly the lightest 18' dyne with a sub floor. Taking offers.
Not to deter from your sale but I think my composite "1972 Keel Up Restoration" will be lighter. My floor also extends all the way forward. But yours floats - mine not yet. Good luck with the sale.
Without motors, the scales would be close. Your core is lighter, but my floor is right out of Scaled Composites. If I end up keeping it, I'll be looking for an Opti 250.
