What is the best material for bolts and cotter pins on deck?
For deck and cockpit, A4 stainless steel is recommended as it withstands continuous saltwater exposure. A2 is only suitable for protected interior areas. Brass and bronze are good alternatives on wooden boats but should not be combined with stainless steel to avoid galvanic corrosion.
How do I know if a cotter pin is the right size for my bolt?
The cotter pin diameter should fit snugly into the bolt's hole without binding. Once inserted, it should spread open cleanly without breaking. If it's too thin, it won't be secure; if it's too thick, it will break when spread open.
When should I use blind rivets instead of solid rivets?
Blind rivets are the right choice when the back of the connection is inaccessible, such as when attaching panels or trim. For connections under continuous stress or safety-critical applications, solid rivets are preferable because they can withstand higher shear forces.
How often should I check bolts in safety-critical areas like the rudder or rigging?
At least once a season, ideally before and after the winter season. Pay attention to corrosion, cracks, and secure fit. Cotter pins that are bent open or visibly corroded should always be replaced – they are single-use items.
