A sailing boat in two bags.

Published 21 October 2026 · WHV · Public-source editorial note

A sailing boat spends much of its life waiting. It needs somewhere to stay, a way to reach the water and someone willing to organise both. Marion Excoffon’s Tiwal treats those apparently secondary problems as central. The boat shown here is an early Tiwal 3.2, with the designer on the water. Its descendant continues the same practical argument.

Design the days when it is not sailing

The current Tiwal 3 combines an inflatable hull with an aluminium frame and a boomless sail. It dismantles into two bags rather than requiring a permanently assembled hull. This is not a claim that two bags are weightless or that every beach is a suitable launching site. It is a different relationship between a sailing boat and the space, transport and routines available to its owner.

That can matter more than a specification that only becomes useful on an exceptional day. A person with limited storage might use a portable boat more often than a larger craft that is difficult to reach. The design makes a potentially valuable connection between an enjoyable activity and the logistics that determine whether it actually happens. Accessibility here is physical and practical, not merely a lower price.

Portability is an invitation, not a qualification

Read the manual, check the operating category and choose conditions appropriate to training and local rules. Ask about sail options, inflation, repairs, rinsing and drying before packing. A portable boat still requires seamanship and care. Its enduring idea is modest and powerful: sometimes improving an experience means designing what happens before it begins and after it ends, not making the experience itself more extravagant.
