Before I bought my Bombard Explorer DB 7.30 I spendt some time looking at different RIB type boats.
Things I consideret was strenght of the glassfiber hull and how its reinforced.
From Zodiac, the explorer DB 7.30 is the onlu hull where they have built it strong enough to cruise in norwegian conditions, with som payload in the boat. The småller modells are not even near it regarding strengt in the hull construction.
And I also looked at the pro series from zodiac, but when compared it's looked not strong enough to take on heavy sea and som wind speed up to 30 kts.
Know I have testet my bombard at wave height up to 4 m, 30kts of wind, combind with an excellent engine from yamaha, the F225, its easy to handle in tough sea.
The engine makes sure of the right power for any condition is aviable, enough top speed for waves below 0.5m height.
