How about a surfboard which has a Bert Deck with a Dale inflatable bottom, with fins. No Foam but with dimensions close to a standard board.
How do you think it would perform ?
been thinking about this for a while now.
on one of my future EPS project I’m gonna route out the entire bottom up to the rail and after glassing the board glue in either a real soft closed cell yoga mat or soem type of inflatable thin air mat.
seem like you just want attach a airex/divinycel top shell clamped onto Dale’s mat.
If it’s too stiff it won’t work the way Dale would want it. But if you could stengthen but not siffen some cheap 1lb EPS that might be a project as the 1lb EPS stuff is very floppy. Maybe just rubber cement a large boogie board to the top of one of dale’s air mats.
Either way it would defeat Dale’s theory of manipulated floatation. He doesn’t like to fully inflate his mats so you can manipulate and dynamically change it’s shape by hand pressure as you ride them.
I was thinking of something only about 2.5" thick, but obviously you can adjust pressure to suit your weight. The deck would need to be beefed up.
Trying to visualise something like a 7’ SIngle fin with pnumatic chambers about 2.5" thick built like this, I cant see any reason that it would not fly down the line. But would you need to retain solid rails to make it turn.
Certainly it would be the ultimate travel board, You could adjust pressure to suit the conditions, or perhaps the design need high pressure to make it work, like 20lb PSI
