Sports Boat & RIB Show
Weather looks good at the moment. Free to get in, lots of on water displays, safe parking if your going by car, access by water if your on boats.
Looking at the list of exhibitors, there should be plenty of ribs there to look over!
Even if you dont like the show then a trip to Pitcher and Piano or Banana Wharf must be worth a look!
