How can I stop my boat from sinking?
 
Hi all,

We are planning a voyage where the possibility of hull punctures are very real! I wanted to ask everyones opinion on techniques and equipment we should have on board to respond to a small to large hull puncture. I have heard of people using wet cure epoxy, cushions, sails any suggestions???

Please check out our rare and remote voyage we would like your feed back a

Northwest passage on a shoestring

Thanks !!!

Most folks who venture into ice use steel hulls.

You seem to have identified some temporary fixes. More permanent ones will be hard to hard in the Arctic.

carry a complete damage control kit. This is a small duffel filled with assorted sizes of plugs & weges. Also you will fiber-glass repair kits, pipe repair kits along with juliet patchs for the pipes. Spare hull fittings, if possible. Also sheet rubber, canvas, lots of assorted pipe clamps. Several tubes of caulking compounds & adheives appropriate for your vessel.
Assorted gasket material, spare parts, for engine, commodes, fresh water, salt water and bilge pumps.
And practice with said items so you can fix anything when you are far far away from any support facilities. This includes replacing fuel pumps, injecters, filters, and so forth. Climbing the mast and making repair high in the air. This includes the shroud and stay fittings, antenna fittings, lights and so on.
In fact you will become very knowledgable about every little detail on your vessel.
And if you have a steel hull? a small welding machine and learn to weld.

Avoid the ice. If you hit a large piece of ice, the damage is likely going to cost you the boat.

You will need two focuses. The first and most important is the temporary/emergency response. These include wooden or newer tapered rubber plugs of many different sizes. I just ordered a product called Stay Afloat, that looks like a wax that will stop a reasonably sized leak. stayafloatmarine.com Then you have the outer hull mating that you tied under your boat. I've always struggled to imagine that working, but others might know better.

Once you are assured to remain afloat, you then need a limitless supply of materials and tools to make a durable repair, based upon your vessel.

I think the approach you take in the colder northern waters Exiles will be dealing with are going to have to be very different from those taken in more temperate waters. Hypothermia is a huge problem when working in extremely northern waters, like he will encounter in a NW passage attempt. That changes the tactics you can use. If the water is 70˚, you can fish around in the hull and try to stop/reduce the inflow without much risk. When the water temp is 40˚, that is no longer a really smart option.

Also, with water temps in the 40s, the chances of making permanent repairs basically goes away on a fiberglass boat, unless you can find a waterproof epoxy that can set underwater in temperatures that low. I know COLDCURE epoxy works in temps down to about 30˚F, but I don't believe it will set underwater. None of the underwater setting emergency epoxy putties that I can think of will work in water that cold... so a permanent repair is very unlikely.

Wasn,t there this book abour a chap named Shackelton and an Irish lad called Crean.:)
Their boat didn,t do so well.Course it was made of wood. Be luckier
Safe sailing.

Don't go near ice in a plastic boat!

I have been on a heavy steel boat that went through light ice floes...My plastic boat would have been badly damaged.
