Verdict

The Mar Sea SP 100 is a compact Italian RIB that suits short coastal trips, watersports, and day-charter use. Its strengths are simple handling, usable deck space for its size, and workable 40–70 hp setups; its limits are range, shelter, and offshore comfort.

Pros

  • +Compact 19 ft footprint makes it easy to launch and berth
  • +Can be run with modest power, keeping fuel use and running costs down
  • +Seating and sunpad layout are practical for day use
  • +Light hull and RIB format should make it responsive and easy to handle

Cons

  • Limited livability for longer outings; no cabin and minimal overnight utility
  • Small fuel capacity on some versions limits range
  • Exposure to spray and sun is typical of this class
  • Performance depends heavily on engine choice and load

The Mar Sea SP 100 is a compact rigid inflatable built for straightforward coastal use rather than extended cruising. Public listings place it around 5.7–5.8 m in length with a 2.3–2.4 m beam, five air compartments, and seating for about six to seven people depending on fit-out. That makes it a practical entry-level day boat with a simple deck layout and a clear focus on open-air boating.

On the water, the model is generally described as a lively, efficient hull that works well with lower-power engines as well as stronger 60–115 hp setups on some examples. Reported cruise speeds around the mid-20-knot range and top speeds up to the high-30-knot range suggest decent performance for a boat of this size, with handling that should be predictable and easy for less experienced skippers. As with most small RIBs, comfort will drop as the sea state builds.

Comfort and livability are basic rather than luxurious. The SP 100 is suited to day trips, swimming stops, and short transfers, with sunbathing areas and open seating more important than interior accommodation. Value is strongest for buyers or charter operators who want a manageable, versatile RIB at modest operating cost; it is less compelling if the goal is long-range cruising, weather protection, or overnight use.
