Spectra and other high-tech composites are sometimes used in place of steel. The material generally doesn’t develop sharp snags as stainless steel cables do, but periodic inspection is critical. “Spectra has over three times the strength of steel wire, but only when it is intact,” Thomas says. Sun breaks down Spectra, so the material should always be stored completely inside the davit. Address any signs of chafe coming from inside the davit immediately. Stainless wire is more forgiving, but when internal components aren’t working smoothly, loads increase dramatically. “Relax the cable and look in and inspect everything. You should be able to spin those pulleys freely, and they shouldn’t wobble,” Thomas says. Even with regular checks, he says, davits should be serviced every two to three years.
