Square Ft Needed

[Riptide]

I'm going to be putting Signature Honey Teak on my Typhoon in the next week or two then when that's done I'm going to put new non-skid down.

How many square feet of Honey Teak and Non-skid am I going to need? This stuff is expensive so I don't want to go overboard. Does 50 sq ft of teak sound over the top, seems so, but the number do add up? Also, short of driving over to the boat and measuring things I'm wondering if someone knows the amount of non-skid I'll need.

Thanks in advance.
