Our hearts and prayers go out to everyone in Boston and around the world who are impacted by the senseless tragedy there. God Bless and know you are in our prayers.
We had fun making that GoPro video, but as we mentioned it is great for artistic creations, but not so much for the documentation of anything useful or comparative. The wide angle lens distrorts things so much, in our opinion, that it just isn’t useful for that purpose. Even the non-wide settings seem to distrort the image. We’ll have to play with it more and see what we can come up with.
So back to a normal digi-cam without that wide angle lens and ditto for the video.
We slapped a single trailing fin into the slab o’ foam “wakesurf board” and took it out for a spin. The idea was to see if the increased buoyancy could account for anything useful in terms of recovery, drive, speed or anything quite frankly.
So here is one picture. We started by fading as far back as we could. Conceptually, the idea of more buoyancy has been said to incraese float (not) drive (not) recovery (not!)
Same old, same old
Ok so here is a TOO long, unedited video of the process that created the above pictures.
If you perfer to view the above buoyancy testing video on your youtube console, or if you’re here on your mobile device, there is the link. We’re still having trouble with presenting video when the page is rendered on a mobile device.
We should review some of the issues with the slab o’ foam. As the name suggests it’s a slab of foam! The rails are thick and the plan shape is ugly and doesn’t really aid the board in wakesurfing in anyway. In terms of streamlined, it’s not at all, it’s a BLOCK.
So as you saw above, the board tended to lift on the inside rail. It captures LOTS of the lifting forces, but really made it hard to actually ride on the face. Partly that is due to the shape and partly because it’s 3 inches thick and square!
Buoyancy does come into play, to some degree, we saw it with the scale testing (and we should add that wasn’t meant to convey it was scientific. The scale added some weigh all by itself and we couldn’t really push down uniformly nor did we place the scale at the exact midpoint of the wakesurf board, etc.) BUT it tends to be overshadowed by things like drag and an efficient design. The Slab o’ foam was not well designed.
Also Volume isn’t as useful a tool as some would make it sound. Our Good Friend Ed Sullivan relayed a comment about his Kroeger shopping bag wakesurf board that weighed in at around 26 pounds. It’s volume was fairly common, but ignoring the 26 pound weight would be extremely misleading. The best and most uniform data is density, which takes into consideration both weight AND volume. Down from the face, but not a gopro video length
Thanks so much for following along, we really appreciate it!
