Tommy beautiful boat, Steve it does look like he has a little shag going on with those pillows
Actually I think it is a good idea to be able to customize when you are buying new, lets face it not everyone has the same taste. I remember long ago when we almost bought new Terry told us he had a customer that had some type of meat locker added to the cabin

Even though I LOVE our Black Thunder when I can't sleep at night I think of the things that I would add if we could buy new
For what it is worth here's my ideas:
I would make the cockpit longer and the cabin a few feet shorter. We had a bit more room in the cockpit of our raised deck 40' Scarab and it was nice. We also had a flip down seat behind the double driver seat and that was great, I see they now have that option in the new 43"V Nortech. The extended cab is not for me, Ian already said we would have the one with the big engine compartment. Also school bus type seating is not for us, we are into socializing in the cockpit

(when not underway of course

)
I would also design the interior couches so they could be slept on a little easier. Not as pretty of a design, but flat couches without the raised roll at the edge, and a straight line make the benches more practical if you have to have an extra guest overnight.
The thing I would most want to change would be the easiest, is the way the back bench in the cockpit has to be slid forward before you can flip it up, and then you flip it up from the back towards you, this is VERY ackward

Each time we have to get something that has been stored in there, the cooler and all the passengers have to move forward before you can open it.
Some of my ideas might have already happened, our's is older and I have not seen that many new ones to compare ours to. However even with the few things I would change I LOVE our Black Thunder, like Steve said it is very solid and takes the big water very well, we have been out is some stuff that most other offshores would not attempt. We are also sleep aboard people so the queen size bed, storage lockers and stand up head is a real bonus. I have seen a few cabins in the newer cigs and can't believe how most only have half a cabin.
Tommy where do you run your boat, you should add your location to your profile.
