You really need a cab if you are doing serious offshore fishing IMO....
The novelty of toughing it out and being cold and wet and driving 60-70 kms home in a 15-20 knots quartering sea will wear off real quick in a CC...
most every reef trip I do is 50-80 km's out and almost always involves afternoon sea breezes on the trip home....I hate being in a centre console or even a runabout in those conditions.....I used to plan my fishing trips based on the forecast direction of the wind for the return trip...but even then it often changes from NE to NW the closer to land we get....had one return trip that was 4 hours of getting pounded and soaked driving all the way into a head sea.....with my new rig it doesn't matter...
its the reason I went to a heavy hulled, deep V, centre cab, hardtop...5 minutes to put the clears on for the trip home and its dry and sweet..
Also great for keeping all your gear dry and somewhere comfy to sleep...you can toss lures from the front and its a great area if you want some space from those on the rear deck...
We also had a Spanish wrap the line around the trolling motor shaft on the weekend..quick and easy to get along the side of the cab lift the motor with the rod in the other hand and quickly fix the line and still land the fish...would have been a different story if the line got picked up by the prop but we got lucky..
