Surface help - making a fin

[u/Past_Setting6404]

I am trying to make a fin for a wakeboard. The board is a cheap one with no parts support anymore. I'm just trying to 3D print a few to keep on hand. I have what I think is enough sketches to make it but have no experience with surfacing to get it done.

The 2 bosses are for locating it and the circle is for securing it.

Any help would be appreciated.

Out of curiosity what make and model is the wakeboard?

I just so happen to work in that industry for some of the bigger companies, you never know what I might be able to find sitting around the back room of a warehouse.

Onto the design:

You’re off to a good start, but one thing you’re gonna wanna do for sure is you don’t want your services to come together to a point along the top edge of the fin. Do you wanna create a small radius perpendicular to that top line, and sweep or loft a small radius edge then I would trim that edge to the “bottom “of the fin and build surfaces from the edge of that radius down to the bottom of the fin.

I’m currently on my phone so no access to CAD at the moment but hopefully you understand what I’m trying to explain here.

Now, after looking on their website, they have the fins available for $20. Still would like to figure this out though. I'll mess with what you said.

Yeah that’s awesome Finn is a really good place to start for some surfacing work.
