O-K-A-Y …
At least now I know it’s a SINGLE titanium fin you’re wanting to make REALLY thin .
The question now …
WHY ?
What is it you are hoping to do ?
…just curious, Gary …
ben
looks good …I give my sign out on the model .make a model keep the expense down… any baffling in the bladder [ sealed air chamber ],lets see the plan shape and side view this could be the modification the world has been waiting for…transitiions fron hard to soft are going to be the most interesting and the envelope around the fin too will be a challenge …ambrose… mid term paper due april !st and !st model to be delivered april 22,to the Lydgate campus
Aqua, take a look at the zodiac type boats. i think there tech could be scaled down to accomplish what you are thinking.
Yeah, I was thinking the hypalon material too. Dale would know better what to use.
The fin might not be as difficult as you thimk Ambrose. The bladder could float all around the fin, being attached to a sleeve that the fin slides into… The fin could be dropped in from the top of the deck into a slot, kinda like a dagger board.
If you mat guys get the drawing, I’m curios to know what what your initial thoughts are.
sleeve hard or soft in nature will be a wear spot wether high inflation or reduced inflation the achillies heel of centerboards as well…
stiff sleeve or soft sleeve? the fin not difficult at all floating arround will be subject to chafe at reduced inflation…ambrose…the bulge afetr the deck is weighted in the water will cause the air bladder to mushroom out
Have a closer look at the tail of your stingray AF65. Then you can avoid the wear and tear of placing a fin between 2 chambers. Imagine the primed area on the hull as air bladders. I’d form the rails a bit better so they act like perimeter stringers
Now off you go and make it happen…
cheers
