I think it was 2008 for the head in the console/large console option (no coincidence with a fishing wife on my purchase year). It is now available on 21 as well.
The deep V and bracket work just fine in all sea conditions, in fact it is very safe in a following sea. 2 foot and up following sea and trying to run at plane speed and higher is sometimes a challenge or I should say not my favorite. I haven't really rode on a 23 CC that does this condition top-notch really well either. Parker is still about the biggest 23'CC on the market with 23'6" and full transom due to the bracket design. Bigger tabs and a 4 blade prop would improve this running condition. Again, I am trying to run as fast as I can and that is tuff in any following sea.
