sponge board fin question

There’s a wave park going in on the local river here. Looks like it will be something like an Eisbach wave that can be adjusted to suit kayaks, surfboards, etc. Much of the state of development of riverboards seems to be toward modified Simmons-style boards: blunt, wide, and often with quad or twin keels. Going to shape after I’ve seen and tried the wave. In the mean time, due primarily to the bash factor and until I get used it (quite a bit different than an ocean wave), I’m looking at these from CBC. Just looking at it, I’m thinking I’ll want to change the fin placement. Wondering what (epoxy?) adherent would work in terms of attaching the fins . Thinking of cutting off the existing attachment rods and gluing on the polyethelyne slick bottom.  Tried searching but couldn’t find anything.

 

Fins should unscrew or unclip 

Just drill some new holes, maybe plug the old ones and your good to go.

lets look for the barometer

the changing world of “surfing”

the kingdom of Swaylo

the walmart outsourced 

airport givaway board

( my friend  the porter 

gets these as handoffs 

because the freight is 

prohibitive to take em back 

on the plane) now lets see,

back to the Barometer

now the Sport of the Greatest

Watermen in the history

of the aquatic universe

has changed focus to modifying 

the parameters to adapt to static waves in a pond 

to share with kayaks and empty water bottles.

a new high for the design forum.

kudos committed surfer 's.

dora said it when he seeded 

J.J.Moon to the makaha contest 

as the midwest mud river surfing champ.

…ambrose…

modify and adapt

yes drill new holes and refill old holes with old boogie board foam

if you dont the holes will cause drag and slow down the planing

speed.

 

 

Big help: thanks all. The future fin option looks interesting.

Definitely different than ocean waves - no momentum, almost like the difference between riding a stationary bike versus riding on a road or trail. A palliative to mitigate the current remove from the ocean. 

The fin kits for soft boards are installed via holes drilled right through the board. As ambrose suggested, just drill some new holes and plug the existing ones. Stuff some packing foam in the holes and seal them with silicone caulk or hot melt glue. Why complicate a very simple thing?
