Why not put a float at the masthead?

In principle, Tiwal does not recommend putting a masthead float on their inflatable sailing dinghies, for the safety of the crew.

With a masthead float, in the event of capsize, your boat will remain on its side. The float then makes it easier to right the boat. But if you have windy conditions, the hull of the boat will catch the wind and then risk being blown away from the crew. They would then have to swim back to the boat. This is a danger for the crew if they can’t reach their boat.

Without a float, the boat flips over completely – it will “turn turtle”. The overturned boat will stay next to the crew. In this case crew are safe beside their boat. They can then proceed to right the boat.
The only instance where we might recommend the installation of a float at the masthead is for boats that have to pass a shore break on the beach before reaching their sailing area. In the event of capsizing in waves in shoal depths, the mast would risk hitting the bottom with force and may break. The installation of a masthead float for a Tiwal 3 in Hawaii has solved this problem (without any warranty!). And the crew must be warned of the potential danger of having their boat pushed by the wind in the event of capsizing.
