VenturiTube (Anfibio)
Also: drain tube, closable self-bailing
The VenturiTube is the closable drain tube of the Anfibio Revo. Turned outward, the boat self-bails; turned inward and rolled up, it's sealed.
According to Anfibio, depending on the load at most a few litres of residual water remain in the stern, and the boat stays agile and fast. Without a floor mat the drain tube must be closed: turn it inward, roll it tightly at least three to five times and tuck it in. With a fin, the tube is pulled inside because it blocks the fin and can be damaged by it.
