No sailboard can point higher than 45 degrees... most are much more than that. But like any kind of design, there's a tradeoff. Boards that point highest are longer and have symmetrically foiled center fins and/or centerboards or daggers. But these are the worst designs for wave riding. Wave riding boards are shorter and more surfboard like, with multiple fins and no center/daggerboards. For minimal wave riding ability (and no airs), get a longboard sailboard with a big, raked center fin in a box... no centerboard. You'll be able to point relatively high, using that big fin and a lot of windward rail, but you'll just be cruising the waves. Also keep in mind that more wind will let any board point higher.
