If I replace the stringers in a 30' SportCraft, don't I want to use White Oak Stringers with some type of bedding under them?

Re: White Oak is the best for stringers, Right

White oak has been a choice of quality wood stringers for many years.. I would bed them in epoxy. I have seen some here like to "float" their stringers to avoid a hard spot in the hull. I have no knowledge as to where this procedure came from.

Your SportCraft was built in South Florida (I assume, all I know were), they are a well built battlewaggon with a stiff hull that can take a pounding.

Good Luck!

Ayuh,... While that is True,...
White Oak, Must be Boiled before it's used in a boat,...
Otherwise, it Rots extremely quickly...

Bondo is correct there, and yes it takes a long pot. Furniture makers have used white because of its bending quaility. It steam bends really well (I've done it). The boiling is done in a caustic solution,(not just water) mainly to kill fungus and the such that's in the wood, to help prevent rot. Can you not use marine grade plywood, you can laminate pieces together if you need the bulk. Or are you going to steam bend it to form a keel or somthing of that nature?

Wow, haven't heard anyone mention boiling white oak it YEARS, way to go. Is white oak even used in boats these days. I haven't seen it ever, but I only deal with smaller rigs. But I do know about boiling it.

Ayuh,... There are a few Antique Wooden Boat rebuilders up here on the mighty St. Lawrence,...
I was at 1 recently, 'n he was boilin' white oak for a restoration project boat,...
An old Lyman I believe, not that it matters...
When asked, He explained that without boiling, it would rot out in a year, 2 tops...
After boiling, it should last several Decades....

And, Yes, it takes a Huge pot,...
His was about 16' long, by 1' wide, by 1' deep... With a lid as well...
The propane burner under it was also quite an Unusual piece too....

:DIn my wood working I Steam bend White Oak frequently using Schedule 80 PVC, a NEW (EMPHASIS ON NEW!!!!) 5 Gallon Military Style Metal Gas can that NEVER had anything but water in it and a gas burner to boil the water. Put a heater hose on the the spout of the can and attach it to the length of pvc. (Have done up to 20 ft) cap off the ends (With a few vent holes and within 15 minutes it is Steamin HOT. Less than $50.00 bucks and you can have an OAK BOILER!!!

I'm jus sayin...

Re: White Oak is the best for stringers, Right

It's funny, not one of the wooden boat builders/restorers that I've ever worked for or with has boiled their White oak, UNLESS it was being steam bent.

I'd be interested in seeing a reference to the reasoning behind it somewhere- I've certainly never heard of it. White oak has been used for centuries as a boatbuilding wood without any 'treatment', such as boiling... Seems like an unnecessary step to me. If you are bending the frames, of course you've got to boil (or, steam) the wood for flexibility. All the framing, knees, and deck beams in my neighbors Alden 309 are sawn white oak, and going on 85 yrs old. Sure, there's been rot here and there, but that's to be expected in a wood boat over time.

Another question would be why not use MG ply for stringers ???

Because I dont think I would use white,red,green solid wood for stringers...mebbe its just me though..

Good debate I guess...

Get your boiling tank out and start bending those stringers alinea aki.. ( straight ).

Good luck mate..

If they are that concerned, warm the White Oak and saturate it with West System: Gougeon West System. Note: Whiskey and Wine Barrels are made out of WHITE OAK! Not Red Oak...

I'm not bending the stringers. Why do I need to boil? The white oak lumbar has gone thru a klien. Going to use Smith's & Co. Tropical Hardwood Expoxy.

Re: White Oak is the best for stringers, Right

A few years ago, I started an old speed boat project. Changed transom & started on stringers. All the info I received, said the best was white oak. its strong. I'm laminating the white oak. This came from Jamestown Distrib. & another boat builder on the east coast. And I was told to use only Smith & Co. Epoxy period. Theirs seals into the wood. So I did more research, they are right. I picked the best epoxy. Worked great. Now, I'm the process of buying a 30' Sportscraft. Very well know to rot. I want to fix it one time only. With all the hands on members here, I'm filtering info. Finding out what works and don't work. This is why I want to use the White Oak Stringers.

It's been a while since I read it, but I'll do some research and find the articles for you. I think I have copies of some older wood working magazines in the shop, that have some detail on the need of boiling it. I remember it had to do with killing fungus in the wood. Now this might just be in certain areas that are more prone to fungus. I'll find them and post for you, might take me a few days.

Thanks, I'd be interesting in seeing this. I had wondered if perhaps it was a regional thing. I had just never heard of it outside this forum- And I've been around wooden boats all my life, as was MY dad, and HIS dad. My Grandfather worked for Lyman in the 50's, and build boats before and after that, as did my father. I've 'cobbled' one or two together since then myself, too.

Ayuh,... I spent a couple hours googlin' yesterday, 'n found Nothing....

I'm basing my info, Only on the advice of the ole salts I've talked too....

Maybe it's pure Bullship,... Donno...

Btw,... I Did find many references sayin' Epoxy should never be used with Any oaks though...
1 of the main reasons White Oak was used in boat building is it holds Fasteners so well...

Re: White Oak is the best for stringers, Right

Hi all, I have been going to Skiff Crafts factory open house for 8 years now and thay explain how thay build them.
I know thay use white oak for the keel and ribs. Thay steam the ribs for bending but thats all.
About rot, I have a 1961 18' Henry thats been in our family for 50 years, Yes I found some dry rot on a brace and a couple of ribs at the keel and when I took it back to Skiff Craft thay repaired it.
I know thay use some green wood preserve but I don' t know the name. Thay do varnish all the inside too. I have a 22' Skiff Craft Weekender and six years ago I replaced two foot of number one plank at the back. I was able to check the ribs and keel on the bottom and thay were solid as a rock, just discolored.

Re: White Oak is the best for stringers, Right

I just checked out my personal stash of books.. I did find this about White Oak..

From " Cabinetmaking and Millwork " by John L. Feirer

White oak has " tylosis " which makes white oak more resistant over red oak ( red oak does not have this ).

After reading/researching more on tylosis I have come to a personal conclustion that white oak does not need boiling..just proper drying ( OP stated that it has been kiln dried ).

YD.
