According to the original post, It appears Bryan was redoing his deck the week of June 2003 [img]/images/graemlins/confused.gif[/img] But just in case he hasn't completed it or for reference to anyone else doing non-skid to their boat, below is a tip to help you cruise thru the task.

I recomend that you use a two part paint as mentioned by others and follow Fellowships advise on the grit mixture.
The following picture will show you the roller I have used for years when applying non-skid as it has special "LIFT" LOOPS that create a uniform texture finish. It brings the grit to the center of the paint preventing it from settling to the bottom or laying on the surface. After masking off all areas that you DO NOT want the non-skid finish, it is wise to put up a splatter barrier along the sides, console and rub rail etc.
You can then brush on the non-skid paint mixture with a throw away brush. Do approx 2' x 2' area at a time and then come back with this special roller and smooth out your paint. Each time you brush on a section "roll out" the section before along with the new section thus preventing "overlapped" marks and "lumps"! [img]/images/graemlins/blush.gif[/img]
This roller is made by Shur-Line and can be found at Home Depot or specialty paint stores. You can cut it into (3) 3" sections and use the mini rollers for the tight areas. [img]/images/graemlins/wink.gif[/img]
Good Luck!
