If you read the end of the video it says the mast was an experiment. The cross section was 55mm.
We had not sailed this type of boat before and did not realise how much stability it is has - much more than a normal 8ft boat - so it puts more stress on the mast than a boat that falls over easily.
Because we were serious about getting it right we built four masts and four sails - all a bit different to find the best combination.
Since then dozens of boats and not a single problem.
First is that it is that you cannot have a taper - mast more flexible as you go up the mast. This means if the bottom is strong enough the top is too stiff and the boat will fall over easily in stronger winds. Flexiblity makes it a dream to sail.
The second problem is that it is hard to get aluminium of the right size. To be strong enough the aluminium needs to be about 62mm diameter with 2mm wall.
Not available many places - and it hurts the performance.
If you sit within the waterline perimeter, then if this happens or a hole in the wind it does not capsize. If you sit outside the perimeter, it will capsize if wind pressure is lost. So it is best to have heavy weight but not too far out.
lol, wow. I was expecting a normal capsize, not the mast snapping in half :)How much sail are you running? looks like a lot for a PDR, looks like fun.
Awesome! Heeling like a Hobie!

There are problems with aluminium.
First is that it is that you cannot have a taper - mast more flexible as you go up the mast. This means if the bottom is strong enough the top is too stiff and the boat will fall over easily in stronger winds. Flexiblity makes it a dream to sail.

Could you put a jib on that somehow?

There are lots of different rig options ... Most don't use jibs because of the extra rigging and fittings involved ... but there are some.
You generally need a bowsprit to get enough length to separate the forestay from the mast.

The standard sprit rig sail we are carrying is 82 square feet (on a stiffer and stronger mast than this one!!!
There is also a lug rig version wit 89 square feet.
Boat is easy to control up to 25 knots of breeze because of the huge stability of the square hull.

Just on the river near home. To be fair, well lets just say it wasn't unexpected! P :)
