Our Gemini RIB
has now been in the water
essentially full time for 9 years. It's powder coated hull
has numerous scratches and dings reaching down into the metal. There are no signs of corrosion
anywhere. We use no zincs or other means of protecting the aluminium. It is on its second set of tubes, and will soon need its third (the first were burned up by the mongrels who stole it when nearly new).
The hull, which is actually made by Swift in Australia
, has exceeded our expectations and seems essentially bulletproof (metaphorically). If we were to need to buy another, I would definitely buy one with such a hull.
