Powerboating has suffered a great loss with the passing of Austin Gunning. His smiling face and positive attitude brought happiness to whoever he met. A regular contributor to powerboatracing.ie, his love of all things powerboating was plain to see. Our hearts and sympathy goes out to Bernie and the extended Gunning family at this time.

Some T850 boats have to have the following modifications fitted to comply with new Cockpit compliance rules as per RYA Rules.
This only applies to the Bristol and Hustler hulls without the vertical lip on the sides. A modification has been devised which basically consists as a pair of 100mm deep by 40mm wide box sections along the open section of the cockpit but ensuring the minimum height from the steering wheel to behind the seat.
The fibreglass thickness is 3 mm for the top section and the base consists of 8mm plywood bonded in, then glassed over with a further 2 layers of strand mat.
The section is secured by four M6 bolts at 35mm centres, and bonded to the upper deck with industrial grade adhesive.
Tested under Race conditions the modification was a total success, not only giving the added protection but also increased rigidity to the upper deck, at minimal extra weight.
Hulls which already comply and therefore need no modification are
Tornado, Torenvliet, Grupstra and Blu Fin.
Please note the minimum cockpit depth is that of the Tornado which is 464 mm.
