Fastening material

[stefos]

Hi i am Stefos and i write from East Aegean Greece (excuse my bad english). I ordered to a boatbuilder a 9meter wooden boat. We are going to use pine tree (pinus brutia). The fastening material i can find in my island shops is galvanised nails or stainless steel nails and screws. Most boats here use galvanised nails but after 15 years in the water they rust so i don t want to use them. I read in other threads that stainless is not suitable for under water use but i don t know if that means is worse than galvanised nails. The question is should i use stainless nails or should i look for other material?

If you can afford it, I would recommend to use silicon bronze screws or copper rivets (nails and roves).

Proper galvanised boat nails like these from the Glasgow Steel Nail. should be an economical alternative; at least here in the US, they should last about 40 years or so. The downside is that the wood around the fastener will become "iron-sick" over time -- a chemical interaction between the wood and the nearby iron effectively oxidises the wood, making it brittle and weak, looking as if it was burned in a fire.

Hmmm....It looks like Glasgow Nail is making reproductions of Mustad's old Eckspik (square steel ship spikes)-- http://www.glasgowsteelnail.com/mustad.htm

...use silicon bronze screws or copper rivets (nails and roves).

I second that. If you must choose between galvanized or stainless....I wonder which is better underwater. There have been some carvel planked boats built with Stainless fastenings below the waterline, but I have not heard how it worked out. This is another thread though.....

Go out of your way to get silicon bronze screws or copper rivets. It's worth it.

Thank you all for your advices and the addresses.

Now you have to do your part and share pictures and the story of the build

Doug

[stefos]

The build is going to start in January and expect to finish September. I have in mind to share the pictures.

[donald branscom]

If you use stainless below the water line or, AT the waterline it should be 316 type stainless steel.

[MRJarret]

Stefos,

Welcome!
Is the build a caique?

[stefos]

In greece we call caiki (from the turkish word caique i think) all the wooden or traditional boats from 8m and more. But for every kind of boat there is a name(trehantiri, perama, varkalas and many more). This boat will be a varkalas. It s a boat with flat(i don t know the correct word) stern like wine glass and a raked bow(older varkalas had vertical bow.

stefos, whats this

[stefos]

This is a trehantiri. Now trehantiri is a fishing boat (the most common in Greece) and you can see it 8m-25m long. Bigger trehantiri (15m and more)with bigger displacement used to be commercial boats.

[stefos]

In the old times trehantiri was a sailing boat and had deeper hull and some difference on the deck and the bow. They had 1 or 2 masts and they could carry latten, sprit, lugger or boom sails. Fishing trehantiri has great beam(1/3 of the length)

[KAIROS]

Found these on the web:

[stefos]

Yes these are the boats we call varkalas. The model is from a varkalas that was builded 1918 and i remember her since i was a child carrying building matterial (with her deck in the water) until 1990. Now we see her resting in the port of Chios.

Good for you!! Are you going to rig to sail? or motor?

[stefos]

Ι am going to use cutter rig and a motor ( for the calm and the fishing)
