IIRC, the Pico has more than one strap: one long-ish centre strap, one small centre in the front (used when sailing double-handed) and two short straps on both sides just inside the cockpit, near the gunwales. Those 'side straps' are used when you need to get the boat upright after a capsize.
Here, the 4 straps are more or less visible: 2 centre straps and 2 short ones on both sides of the cockpit.
The Pico is a widely used boat here at sailing schools. Most have those 4 straps in place. I know that bigger, taller sailors remove the side straps because they're strong enough to get the boat upright again.
Thanks for the info. But do you know if I can add a long center strap to a Pico that doesn't have one? There is no hardware to attach it to, so I guess I would have to drill into the hull?
