We have dove up to 5 (3 tanks each) off my wellcraft 248. I have removed the above deck fish box and helm seat for more room. I couldn't sit down and drive the boat anyway. It defintly rides the opposite of what Dennis said about cat hulls, "They are more comfortable because the don't recover as abruptly (quickly) and therefore, in steep seas they can't recover quickly enough". This boat recovers so fast it hurts, Bam Bam slow down man. I have not been out in much worse than 5's at the end of the day coming back in. Dennis, you have ended my cat hull envy. Now when someone complains about my boats ride, I will proudly answer it's got great recovery time.
