The extra weight added would mean you were shoving a lot more water aside going through it which makes far bigger waves and therefore extra weight increases the wavemaking resistance of the kayak far more than any WL length increase from adding weight could reduce it. The inertia increase seems the most likely reason, that is, if the difference is real and not just imaginary. I wrote about inertia in a post earlier about Doug's experience. My latest post from yesterday hasn't made it to the digest yet. Does that mean I'm being censored in moderation? Did my inertia post get through. I do recall reading someone else commenting on the inertia difference though pointing out that Doug's weight gain may have compensated for the lighter kayak so I'll assume my post made it though and started the inertia track. Another possibility may be illusion. If Doug has gotten weaker as he has gotten older he may not be starting his glide from as high a speed now. Since I haven't seen any tests using both boats under nearly identical circumstances there is also the possibility of misremembering the feeling of glide in his old cherished kayak. Love can mess with perceptions like that. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
