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
Castoldi, in short
Castoldi is a historic Italian manufacturer (Abbiategrasso, since 1962) famous for building its own waterjet drives. Its Jet Tenders are the industrial, robust alternative to Williams: highly valued on superyachts and also in professional and military versions. Maximum hull-drive integration and built to last decades.
Strengths
- Has built its own waterjet drives since the 1960s: total integration
- Robust construction also aimed at professional and military use
- No propeller: safe in swim areas with minimal draft
- Established prestige in the superyacht market
Things to consider
- Premium price
- Specialist jet maintenance
- Range starts at 4.3 m: no compact option
Our verdict
Choose Navisoul if you fit its profile: those who want full customisation and top materials without paying the historic brands' premium. Choose Castoldi if the opposite applies: yachts and superyachts wanting a robust jet tender with industrial pedigree. 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.
