Chassis Fixation

Ok, I have to admit that there is for sure not many people that require a surfboard rack. But at least surfers all around the world know about the Eisbach and Flosslände scene in Munich and will understand this very special need. All in all it is a very individual and complex solution, but still worth to document and maybe interesting for the one or the other of you guys.

Chassis Fixation

The main rack fixation that is mounted to the chassis is made out of a block of aluminium. We drilled a hole with the size of the retainer and cut the block above this hole. Now a second hole had to be drilled and tapped. This hole can now be compressed using a screw to tightly hold the retainer. On the backside of the block we inserted two more threads which will connect to two screws that go through pre-drilled holes in the chassis. In order to avoid chassis damage we put some rubber between the aluminium block and the chassis.

Retainer

Retainer

The retainers are made from steel bars. For the geometry, pls look at the pictures. The exact positioning is done by utilizing the already mounted aluminium blocks. This is in order to secure a parallel and straight fixation. The aim should be not exceeding 40cm of extrusion but to be able to put the foot on the floorboard in the most convenient way. Drill a small hole through each of the retainer bars top side in order to attach a rubber expander that will fix the surfboard and prevent it from falling off. Cover the surface of the retainer bars with sponge rubber to additionally protect the surfboard from any damage while driving.

Set a small notch at the end of the retainer bar (using a file or any appropriate tool) that will prevent it from slipping out or twisting inside the aluminium block. The main screw is supposed to hold the notch into position.

Surfboard Rack

The surfboard rack in action at the Munich Eisbach. A totally reliable and easy to use construction. The board is put in the rack in a way that the fins hold it back from slipping forwards or backwards. The rubber expanders prevent it from 'jumping' out.

You can place your foot in a most convenient way between the board and the Vespa without the board sticking too far from the chassis. No problem either with any angle when turning left or right. Despite the extra weight on the right hand side, the Vespa can be maneuvered without any noticeable disadvantage.
