A world away in another century, Shackleton's ship, The Endurance, was trapped by the Antarctic sea ice and crushed. Taking a page from history, I had a unique opportunity to learn from that loss and test my dad's skills as both a boat designer and builder.

The "pocket yacht" went to sea in a fjord during a snow storm in Iceland.

All of the performance matrix tests were successful. It was stable under sub-Arctic conditions and the damage from ice was within specifications and acceptable tolerance levels.

Shackleton would have been fortunate to have such a fine ship.
