The format for both championships remain the same - identical boats with identical engines and a strict no modification rule that will now be enforced. 

The 150 Class - remains unchanged. The 21ft Cougar hulls will still be propelled by the impressive performance and reliability of the Honda BF150 4-stroke outboard engine.

The 225 class - Under P1 rules the 27ft race tuned Cougar hulls will be fitted with the more  powerful 300bhp Mercury 2 stroke engine. The power upgrade will see top speeds increase from 67mph to over 80mph. Whilst the 4 Nations will no doubt stick with proven Honda BF225.

International venues - 4 Nations will involve five venues spread accross England, Ireland Scotland and Wales and propose a European event. P1 Superstock will host 4 UK venues and two European rounds but teams will have the option to compete for a world championship title, UK national title or both.

Teams, spectators and sponsors will be spoilt for choice in 2010. Whilst the Honda Formula 4-Stroke Series celebrated it's 10th and final year in 2009 it did not signal the end to the most successful offshore powerboat racing format in the world. The extreme high risk close action racing that captured TV audiences from around the world enters the next phase of it's evolution.

The biggest challenge facing the teams right now is:       

Do they race in  P1 Superstock Championship or the 4 Nations Championship
