l am just learning and have no idea. thanks

my buddy is 6'4 - 6'5 he is riding Mickey Munoz 11' surftech epoxy board.That would be a good board to start on. A little pricey though. l recommend bigger & lighter boards. Just because a traditional longboard is tiring to paddle around in the surf, especially when u r just starting out.

On the other hand l ride a 7'6'' hollow core wooden board that l shaped & glassed myself last summer. l am 6'2'' 325lbs. It is all about volume & displacement when u r starting out. look for boards over 3 inches thick. And preferably epoxy so u wo not dent the hell out of them with ur heels.

As u get better everything changes, or stays the same. It just becomes more about preference.

Since your just starting out, in order to develop you '' sea legs try a board between 8'4'' to 8'7'' ( that should be easier for you to paddle ), around 3 inches thick, flatter bottom with turned down rails, and a softer tail radius ( round tail as opposed to a pin tail ). You should have fun with a stick like that in most surfing conditions.

If u r just learning, l would recommend a long board. For a big dude like you, we r talking about something in the 9'plus range, real wide, around 22/23'' on a nice fat blank (3'' thick). l am 5'10 220 lbs (yes, that is called fat.. l surf best at about 200 lbs, but l have gotten lazy this winter). l ride boards from 9'4'' to 7'8 but I've seen lots of big guys rippin' on boards in the 6' range - however, they r very experienced, & VERY good.
Go to a real surf shop (not a bathing suit store that sells some surfboards) & talk to the folks there. They will hook u up with some lessons, & the right board for ur size, beginner skill level & the type of waves at the local break(s) u will be surfing at. Do not buy anything too expensive. as u get better, u will undoubtedly want to change up, almost everybody does ( l have been surfing since '66, & l ride three different boards). Check the link for some good info on some junk NOT to buy.Go for it! Surfing is the greatest stoke of all.
