Reviewer 1 Report

Hi quality well written paper with high impact. 

A couple of potential typos:

line 64: should widespread be wide spread?

line 407: should have be heave?

Thank you very much. We have corrected the two spelling errors.

The paper presents highly accurate experimental heave decay tests with a floating sphere in  the  wave  basin  in  the  Ocean  and  Coastal Engineering  Laboratory  at  Aalborg  University,  Denmark. Also, a comparison of the physical test results to the results from several independent numerical models based on linear potential flow, fully-nonlinear potential flow, and the Reynolds-averaged Navier-Stokes (RANS) equations and high correspondence  between physical and numerical test results is detected. The authors formulated a test case which closely represents the physical tests, enabling the reader to make his/her own numerical tests. They also made the experimental test results public as a benchmark dataset.

The paper is well written and presented. Moreover; the conclusions are supported by good numerical and experimental results. The topic is interesting and the results can be the basis of numerical model validation benchmark dataset of many future works. Therefore, the reviewer would like to recommend the paper for publication.

Thank you very much.

Reviewer 3 Report

This paper provides highly accurate experimental data of heave decay process of floating sphere for validation of numerical simulation methods.  This is very significant and it contributes for development and improvement of numerical simulation technique.
