Inland Branch Annual Concrete Boat Race 2017


The Inland Branch once again, organised their Annual Concrete Boat Race Day, but did not expect the adverse weather conditions that prevailed.

Very strong winds created choppy waters at the East Rand Speedboat Club on Van Rynfield Dam, Benoni, and a huge challenge to the paddlers racing on the day.
This did not detract however, from the fun and competition of the day.

The day started with the judging of the boats that had been constructed by the university students from UJ and Tukkies. The 45 concrete boats were lined up along the lakeside, having been carefully and enthusiastically constructed by the students to prescribed rules in terms of design, dimensions, weight and materials. This year the design theme of the craft was set as a Makorro, and had to be constructed in such a way that two persons could propel it with a paddle. The craft also had to be capable of being lifted by only two team members. No buckles or attachments of any nature were allowed which attach individuals to the boat. The deck must NOT have enclosed the occupant's legs to the extent that it may trap him/her in the case of capsize or sinking. Synthetic materials could be used to provide flotation, but could not add to the structural integrity of the craft.

  • Marius Grassman – Concrete Testing Equipment
  • Jaco du Plessis – Go Consult
  • Andries Marais – Chryso-abe

 The construction of the boats was carried out to the strict criteria, the most important of which was that they must float! The boats had to be made from a freely available, commonly-used cement, mortar or concrete. Lightweight aggregate could be used, and the binding agent had to be predominantly cementitious in composition.
Limited quantities of other materials were allowed, provided that they did not replace the binding action of the cement. The strength and stiffness of the boat had to be entirely due to the cementing action between hardened concrete or mortar and its reinforcement. Non-concrete parts were not allowed to contribute to the strength or structural integrity of the boat and could be removed at the judges' discretion.

Once the judging was over, the racing began, facilitated by Johan van Wyk, Chairman of the Inland Branch and MC for the day, who ably steered the various heats to reach the stage where 3 main 'final' races decided the winners. The racing was very competitive, and different shapes and buoyancies of the boats soon sorted fast-moving craft from the slow. Races took the form of a relay where a 2-person relay team paddled 2 legs across a pre-determined course on the dam. The racing concluded with an ‘Anything that Floats’ open race, and the paddles were ‘flying’.

After all the heats and the finals had been held, the winners in each category were as follows:

A special award, also donated by PPC, was presented to Deon Kruger from the University of Johannesburg for being the lecturer that registered the greatest number of students and boats. A near record number of boats were constructed, totalling 44 from UJ alone.

The Inland Branch of the Concrete Society would like to thank all the Sponsors for their generous contribution to, and continuing support of, the Annual Concrete Boat Race Day! 

Thanks also to the East Rand Speedboat Club for the use of their facilities; ASM Safety Consultants for facilitating all safety management issues, CMS for security and John Sheath for the photographs.
