Well... The SV27 has a longer hull and it maybe more stable in rougher waters. WM doesn´t have trim tabs, which you may have to add, if you use some upgrade props. Trim tabs are needef, if you want to have your WM to run nice and smooth. Haven´t tested yet, but I guess.

Both boats need some adjusting but I have been really satisfied with my SV27. My brother acquired a WM and I am looking forward to competing against him.

I have noticed that it´s easier to find upgrade and tuning parts for SV27´s than WM´s. Also you find more tuning tips for the SV27 than the WM. To get a really fast one, get the SV27.

As I have tested the WM, I can tell you more.
