Another factor to consider is the core material and the lamination process.Seems things are getting better with the major brands doing more pre pegs and heat cures. (Autoclaves coming soon i would guess). Regardind the Cores My own experience points to vacuem infusion being a less consistent and readily controlled (i.e. complete wet out and no dry spots) process then prepeg . With the prepeg the builder has much tighter control on resins distribution and resin/cloth ratio which are both key to a solid lightweight laminate. IMHO , for cores , say NO to core mat . They are all being proprietary as to the exact cores they use in their laminates BUT the new ones from the major ski brands seem to be coming out nice. Epic , I believe is prepeg and heat cure. with prepeg the hybrids seem to be coming out real nice , light , tight and not completely outta sight ($$$$$). My carbon cockpit S-glass hybrid Huki S1-XL came out at 25.2 pounds and that's with a heavier than standard S-glass cloth on the hull (5.7 oz vs. 3.7 oz , ups the stiffness and strength) Now 25.2 pounds is lighter than a lot of "carbon" boats out there.SO..... Carbon and Fiber glass are easier to repair than kevlar , if you sand through to the fabric (which you will) the kevlar gets all fuzzy.Lot's of debate on weight but I reckon that unless your uber elite anything below 28 pounds is plenty light enough and the full carbon super lights are (as noted by the mfg.) more susceptible to dings and off the water failures (easy on thosee rack straps ! ). Real Happy with the build quality and performance of my Huki , while they are hard to get outside the West Coast US , they are awesome boats and worth a look.
