Ultimate BoatingMethodology & sources

Ultimate Boating aggregates and compares public technical data (manufacturer brochures and spec sheets) to help boaters objectively compare engines, propellers, systems and boats.

Independent: no display ads, no sponsored content, no paid rankings.

Privacy-first: self-hosted, cookieless visitor analytics (Matomo), no third-party trackers, no cookie banner.

The site is funded by affiliate commissions (Amazon, Click&Boat): this does not affect prices or comparisons.

Methodology & sources

How Ultimate Boating's data is established and verified.

Available references, dates and technical notes are displayed on product pages. Missing document links are identified. Prices are indicative; a catalogue price is not a sales offer.

No value is invented or estimated: a figure the manufacturer does not publish is marked “n/a”.

Prices shown are indicative (base configuration, options and discounts excluded) and vary with the market, the model year and the dealer: never a firm quote.

For power, the maximum rating stamped on the hull's builder's plate (CE standard) always prevails: we never recommend above it.

Ultimate Boating neither hosts nor redistributes any manufacturer document. For official documentation, contact the manufacturer or its dealer network directly.
