(Reuters) -A barge planned for use building a controversial judging tower for the Paris 2024 Olympic surfing competition in Tahiti snagged on a reef and damaged coral near the contest site on Friday, local opponents said. Residents of Teahupo'o in October protested plans by Games organisers to build the 14-metre (45-foot) aluminium tower to enable up to 40 people to watch, film and judge the surfing at a famed break in front of the village. Organisers including Paris 2024 and the French Polynesia government said last month they had decided building a smaller, lighter tower on the site was the best option, allowing for smaller equipment to install it - but still requiring new foundations in the reef.
