I am surprised that it hasn't turned into an argument about which is better either. It's nice to just let everyone state their opinion, without someone feeling the need to convert them to their way of thinking.

I think cockpit depth is the deciding factor. If your sitting four foot off the floor your probable more comfortable standing. Who want's to be on a pedistal flying off shore? If you have a low profile seats/boat and your feet comfortably rest on the floor I would sit. For me low profile is the only way I feel secure. I think thier is a trend for 100+ mph boats as sit down with race harness's. (seat belts)

Stand.

Stand, I had a 28' Checkmate that had alot
of freeboard & was a stand up. Moved to a
32 fever which is basically a sit down. Just
bought a 35 executioner which is stand up.
I'll take the stand up anyday. You just dont
take the thumpin you get in a sit down.

some days i prefer to stand and some days i am lazy and want to sit :

I have had both and like the stand up better but my sit down cat was a sweet ride too.

Stand, wife sits in all but the worst stuff.

sit down changed my seats in ol from standup I have been thrown out on to the deck and out the side overboard ten years ago at first I add about 8'' to the bolsters and made them narrow by 2'' so 2yrs ago I had offshore performance in cal ,make me a drop out bolster which cuts in and out ,

The only time I ever sit is if something goes wrong and I am ideling back, like saturday when I blew a drive. I think you capture the real experience if you are standing...wind in your face, seeing everything, then again my boat goes 70, I don't know if I would want to stand going 120.

The T/S boats seem to ride more level, so i like the Gladiator well as a sit down.
My '96 TopGun was obviously stand-up but that was the only way to see over the wind deflectors at speed.

I am seriously looking at a Gladiator in the near future so I'd say I'm sold on sitting.
