Below are the surfboard options for building! I have been advised that the first three shown below (the "Waterlog," "Root," and "Steamer") may be the best choices to build for 8th graders, but to be aware that the "Waterlog" may be a bit large for 8th graders to handle in the water! (**Don't worry at this point about wood color! Focus on selecting the size and shape you would like to build!**)
The Waka board below IS an option, however - we have been advised that it is a difficult board to build. Anyone wishing to build this board should be prepared to spend extra time and effort on this model!
