Interior Framing

[glenn.225]

Hi all

Kicking about the ideal of building a 30 ft sailboat, probably cold moulded.

Just wondering what domestic (Can) timber would equate to Meranti or Philippine Mahogany?

My dad always used spruce knees for timbers in dory building, it held up really well in saltwater (20+ years) but would rot out in a very few years in fresh water. I believe this mostly had to do with lack of protection (paint) allowing the wood to get wet. He used maple as well for trim and wear strips.

I have some experience with oaks and find them durable. What about cedar, larch (juniper), etc.

Black Locust if you can find it. Hard but very rot resitant. Used for "boat nails" in traditional boats.

Sorry, but what is Black Locust, which type of tree, where does it grow?

It's a North America tree found in the east. It is being studied to figure out why it last 100 years as a fence post or railway tie. In short, it's strong, cheap and is all that Charlie says it is.

Thanks guys I Googled it, and it seems like a excellent wood.
I guess it grows little far south for me to hear of it. But I'm sure it can be shipped.

Why build in wood?

If you really want to do cold moulded then why not cold mould the frames from the same wood as the hull?

But really you should build the interior first, then the frames, then the hull.

Have built Hartley 32' ferro, Van der Stadt 6.5m, currently fitting out a 44' Roberts steel.

Honestly , I'm not sure which material I will be using. I like working with wood. I have been looking at some of Dudley Dix's designs and like his radius chine plywood building style or I may do a 180 and use steel. I'm a fair welder and like the strenght aspect.

It's still a couple of years down the road. But when the time comes, Boracay, I will be looking for advice.

For this spring I'm going to pick up a cheap plastic.

To me the most sense would be a 40' cat in epoxy/foam/balsa.

Otherwise there are so many cheap plastic boats on the market. Some will be really nice.

..only problem is paying for somewhere for a 40 foot cat to live...that is a seriously big boat.

[glenn.225]

Not to mention cost and time to build. A 30 ft mono hull may take a couple of years to complete. A 40 ft cat could take a life time. It would be nice to have some time to sail, this would be mostly a single handed porject and sailer.

It takes at least 8000 man hours to build a 40' cat of glass and foam, providing one has the know how.

Theres them as build boats and them as sail boats.

But not many as do both...

Exactly

I would like to sail “sometime” and the First Mate would like a little of my time and god forbid, I may have “work” although only part time. So i think a 40 ft cat might be a little much.

BTW, how do you quote two people?

When I was looking to scratch build a boat the only practical way was to do it was in a country with low wages.

With care the Philippines might be practical.

i.e. Plan on one year and employ five semiskilled workers (5 * 365 days * $10 per day + 10% completion bonus).
