Double Hose Clamps: ABYC Required
Is my surveyor giving me the straight story?
Question: I just had a survey done on my boat so that I could renew my insurance. The survey report said that I needed to get my engine’s exhaust hose double clamped to comply with ABYC Standards. Since I just paid a mechanic to upgrade my entire exhaust system, I’m wondering what’s up here.
Answer: Your surveyor is absolutely right. ABYC Standard P-1 addresses engine exhaust systems and requires double clamps at every hose junction in an exhaust system. The standard even makes some very specific recommendations about the type of clamp used. Ask your mechanic if he or she has any ABYC engine certifications. If so, they would be quite familiar with this important recommendation.
