Navisoul, in short

Navisoul is the range of inflatables and RIBs that Caral Marine imports and distributes exclusively for Spain. The proposition is simple: first-rate materials (Hypalon CSM available across the range), real customisation from the yard, and a line-up covering everything from a 2-metre folding tender to 9.3-metre RIBs with twin 350 hp engines. By avoiding the brand premium of the historic manufacturers, it delivers value for money that is hard to match.

Strengths

  • Full customisation: tube colours, material, deck and engine
  • Complete range: from a 2 m folding dinghy to a 9.3 m RIB
  • Exclusive distribution and after-sales service in Spain through Caral Marine
  • Hypalon (CSM) available across the whole range

Things to consider

  • Less brand recognition than the historic giants
  • Distribution network centred on Spain

Williams, in short

Williams Jet Tenders, founded in Oxfordshire (UK) in 2004, dominates the jet tender niche: tenders propelled by waterjet instead of a propeller. That makes them ideal for a yacht garage (minimal draft, contained length) and for swim areas (no exposed propeller). Standard or optional equipment at yards like Sunseeker, Princess and Fairline. Quality and price at the top of the market.

Strengths

  • Jet propulsion: no propeller, maximum safety for swimmers and towed sports
  • Minimal draft and compact size for yacht garages
  • Luxury finish and sporty performance (Minijet, Turbojet, Sportjet, Dieseljet lines)
  • De facto standard on 15 m+ yachts with a garage

Things to consider

  • Premium purchase and maintenance costs
  • The jet requires specialist servicing
  • Less efficient than a propeller at low speed

Our verdict

Choose Navisoul if you fit its profile: those who want full customisation and top materials without paying the historic brands' premium. Choose Williams if the opposite applies: owners of yachts with a garage who want a sporty, safe, luxury tender. And if budget rules, Navisoul starts with a price advantage — though it always pays to compare specific models at equivalent specification.

Our practical tip: before deciding between these two, also get a price for an equivalent Navisoul model. With Hypalon available across the range and yard customisation, it often wins the comparison without the brand premium.
