Funny you mention the R-boat sinking ... We had one go down in the early 90s here in Toronto while racing. Friends of mine where on board and all survived. The boat was sailing off the wind when a rogue wave got them from behind, filled the **** wich then flooded the hull on the second wave. The R-boat is a low freeboard open ****/hull design similar in looks to a metre boat or is it meter ??. Boat was resurected within a couple of days I think.
