Hi Matty,

These bumpers have been around for ages, I think Wouter (Otjes, of DKV) started selling them about 10 years ago.

Check their website (http://www.dpp-info.com/) under accessories.

These bumpers last for years (when applied properly, use contact cement in the correct way, see package for details) and no, I do not have stocks or other financial interests in DPP :D

Hope this helps,

Cheers,

Michiel

all i could find is the 'generic' bumper on that site. The bumper i'm talking about is completly flush with the boat. To me it looked like the boat had been cut out so that the bumper was housed inside it along the boat's orrigional lines.. but that would surely create structual weakness. Anyone know the bumpers i'm talking about? This was my first worlds, but none of the aussies i spoke to about it who have 'been around' had seen them before either!

do you mean intergrated bumpers?

Dave Brown in the UK made integrated bumbers for his Flight boats.
might be what you mean.

Yeah they're what i'm talking about! brilliant idea! reduces drag a fair bit i'd guess. I saw them on the dutch senior teams seamless dynamics though. To me it looks like the boats had to be modified to fit them? but i'm guessing the flight2 is built to take those bumpers obviously. As i said, cutting up your nose and tail would probably have structual affects on the boat, so anyone who knows how they did it please share! :thumbup:

For a while integrated bumbers where illegal, at least in some countries and in the form they use to be.. mainly because they did not have the required thickness down the side, and the edge at the "corner" was too sharp an angle. Now many are building with them for better maneuvrability and speed... speed only regarding the rear bumber.

But dont think about cutting up old boats to integrate bumbers! It will never be worth even thinking about it, especially because only the boats with really flat noses are even able to have a suitable integrated front bumber (if it is not a heavy and expensive one made in a mold)

If you want some of the speed advantage, make sure the rear bumber is big enough to cut "hydrodynamic" :D down the side and still keeping full thickness 10 cm. down the side (interpreted as to the point 10 cm down the center of the boat and 90 degrees out...) In theory you may even cut the bumper to give a minor "lift".. as a spoiler on a car, to keep the nose down for better speed... compensating for the drag of the bumber...??
