The 18XS has a design that is basically equal to the 18X and 16X:
- long waterline for creating a fast vessel,
- sharp bow which has still a lot of volume (more volume than the 18X)
- a wide, flat aftship
- the deck, in front of the cockpit, has cutaways making an efficient, fast paddlestroke possible.
