2020 Manitou 23 Oasis — Should You Buy One?
Typical asking price: $35,000–$52,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
Manitou builds mid-to-premium pontoons with good build quality and an unusual V-toon hull design that handles chop better than flat-bottom competitors. The 23 Oasis is a well-rounded family boat. Standard pontoon maintenance applies.
What we checked
Not checked against public records
Boats are the Coast Guard’s, not NHTSA’s. It publishes a Cases and Campaigns file, but its model and year fields are free text and the recent entries are mostly hull-ID and capacity-label paperwork, so we have not been able to join it to a specific boat honestly yet. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
