How to read the research.

The reviewed set is approximately 25–30 feet, centered on current power catamarans legitimately cross-shopped by a North American buyer considering the Halo 28. The range is a guideline, not a boundary designed to protect Halo. Any future outside-band candidate would require a documented cross-shop rationale before publication.

For competitor vessels, applicable current manufacturer publications and current engine-manufacturer performance bulletins control when they clearly match the model and configuration. Secondary editorial, dealer, forum, video, and owner material may support discovery or historical context but cannot override applicable current primary evidence.

If two current primary sources materially conflict, the value is paused for owner review. For Halo, documented current North American Halo field-test data may control only when the same configuration, context, provenance, and substantiation expectations are preserved. Halo is not exempt from the evidence standard.

1. 01Current manufacturer technical source
2. 02Current manufacturer or engine-manufacturer performance bulletin
3. 03Independent instrumented test with compatible configuration
4. 04Authorized dealer price with exact basis
5. 05Secondary editorial — corroboration or historical use only
6. 06Discovery-only sources — never public substantiation

Empty fields are not filled for visual symmetry. Status language is part of the evidence and never depends on color alone. Read the value first, then use the status to understand what the reviewed sources establish.

Each test is a separate event tied to one model, one configuration, and one or more admissible sources. Engine count, engine model, rated power, propeller, fuel load, crew, test weight/load, weather, water, location, and point-by-point RPM, speed, fuel burn, and economy are preserved when published.

A speed without its configuration and conditions is not a verified performance comparison.

The Costa “up to 65 mph” claim demonstrates the pending state: it remains visible as a manufacturer claim, but it is excluded from verified numerical performance rankings because the required test context was not located.

A reserve-adjusted calculation is permitted only when fuel capacity, gallon system, configuration, and economy units are proven compatible. The formula is fixed for this pilot:

usable_fuel = verified_fuel_capacity × (1 − 0.10) calculated_range = usable_fuel × documented_economy

Conflicting evidence becomes a linked record with each credible claim, source context, materiality, review state, and disposition. Values are never averaged. The current set retains every material disagreement rather than selecting the most convenient number.

A correction requires the challenged boat or data point, proposed correction, supporting source URL, and explanation. Contact information remains optional. Anonymous and identified submissions enter the same reviewed workflow. No submission changes published research automatically.

1. 01

   Submit

   Required evidence and explanation are validated.

2. 02

   Triage

   The issue receives a pending review record and duplicate check.

3. 03

   Verify

   A reviewer checks identity, applicability, units, and source context.

4. 04

   Release

   Approved changes enter the audit log and a future public change log.

Only material factual changes and substantive evidence-state changes belong in the public log. Each published entry should identify the affected boat and field, prior treatment, revised treatment, source basis, and effective date. Internal notes, restricted evidence, reviewer identities, and private submissions remain protected.
