How it surfs
The published numbers put this board firmly in the stability-first part of the inflatable market. At 33 inches wide, 6 inches thick and 306 litres, it carries far more volume than a performance touring shape, which is the usual pattern for boards aimed at mixed family and recreational use.
Because Naish publishes only one size for 2026, buyers whose weight sits at the top of the all-round range should compare the figures against the wider Naish inflatable lineup before ordering. Retailer specifications list no rider weight limit for this model, so that figure is not stated here.
Anyone weighing this against a composite board can read the Naish Nalu review, and the broader inflatable options sit in the paddleboard reviews index. The paddle board buying guide covers how width, thickness and volume interact for first-time buyers.
