A fusible weak-link that can handle the stress for the intended item , but breakPeter_Frank wrote: ...
Then one can discuss whether we want to have "weak" points, or better to have it break totally "somewhere not very defined".
I dont know the best solution and very individual, but of course it is a common issue, on ALL hydrofoils, and the more performing the worse it generally is

I drop in on the chat to put in my knowledge on the inserts coming out/loss of front wing. A lot of these start companies are experiencing the same issues Carafino had back when we began.
Sorry to hear you lost your front wing.
With regard to the stripped insert. First you have to determine what is the material used for the insert. Aluminum or Stainless. Stainless is more favorable as the inserts never/rarely strip. If the insert is stainless, just thread the insert larger to the next size up, if is it still too small, go another size up bigger. Make sure you use a stainless steel bolt also for the size you tap it out to. You may have to make one if you cannot find it. Let me know, we have many sizes in stock for the tapered head.
Try to at least get a discount on the next wing you buy from that supplier. When it arrives, you may have to drill out out either all the hole fittings in the wing so that you can fit your new bolt into the hole size. Or just one hole fitting depending on damage. However, if the wing came off all holes ae damaged. That should fix the stripped insert issue by just threading out the hole to a bigger size. Aluminum is not as strong and should never be used. The do not like salt water and electrolisis begins to weld the aluminum with the stainless bolt.
With regard to the insert in the fuselage failing. This really sucks. because it indicates the foil is not compressed strong enough in the mold under manufacturing methods. Inserts should never break out.
If the insert has failed, you need to get another insert from the supplier of your foil. Be sure to get the screws. We warranty our foil from this as we know ppl hit the bottom, the foil should be designed to withstand a soft to medium impact. What helps is if you come out of the straps instead of stay on the board driving the foil into the bottom or other object.
Nonetheless, Your only solution if you cannot get a discount on a replacement and have no warranty is to obtain the new insert, clean out the damage area of the T bar with MEK or other solvent. laminate the insert back into place. Normally the insert should have a groove in it so the material can adhere and hold the insert into place under stress from riding.
Once you put the groove in with a dremil tool, laminate it back into place best you can. Do not wet laminate it. Use the two part white dry rock hard epoxy you can purchase at most hardware stores.
The most important part is that the wing is straight when it drys.
However, this will not ensure the wing to last a long time. Jumping or hitting the bottom again will dislodge the wing most likely.
Hope that helps.

Carbon fiber and metal fins will sink to the bottom. Even some wooden one will sink, depending on the type of wood used.Arcsrule wrote:so if the breakaway feature was used and it worked, would the foil (or piece of) float?
