Again. Thanks to all for the help. I'm posting from a android cellphone and cant figure out how to give rep-points from this app for now, but I really do apriciate the help.

If it's only 1/4" thick 6" should be fine, that's 24-1. There is much debate about proper torque numbers. It's best to go with a manufacterer's recommendation if you can get it. But failing that it's basically a function of bolt size, material, and lubrication. There are many easily available tables for this, here's an example-

The problem with those is that they don't have an entry for stainless steel bolts.

In case others read this: get the little Handyman pocket-book I use next time at your hardware store (I saw the same ones at ACE hardware). They have all this info incl. for nylon or aluminium bolts etc.

cheers,
Nick.

Well, what do you think? Let's see: SAE grade 2, 5 & 8 so nope, no stainless steel

oooops!

THX for correcting this!

Hi all!
All floors finished! Bolts are in and torqued to 150Nm/70Nm.

The torque table from Bumax should be correct as they produced my bolts!
So... Looks like I'll have to torque the bolts to 330/150Nm?? Sounds like too much to me..

I'll take some photos of the floors today, ran out of juice on the mobile yesterday

Depends on the lubricant you used.

[manitu]

Using wd40.

By the way, measured the boat yesterday.. 30.8 feet.

Then you torqued it right, see my post with numbers before.

The other numbers sound like maximum torque or whatever; and the lack of lubricant correction numbers is also suspect as one lubricant can mean half the torque than another lubricant.

cheers,
Nick.

150 sounds right to me, for a keel that size. Don't gall them or snap them off! Congratulations, sounds like you did a good job. Now the exterior. There will be lots of hard work there, but at least you won't be a bilge rat any more! Sometimes it's actually nice to get under the boat if you've been trapped inside awhile...

Hi folks. Sorry for not updating the thread for a while , but the summer has been busy , with a motorcycle accident and a dog dying (on seperate ocations).


I did allmost no finish work on the outside , just sanded the layup reasonably smooth, three layers of epoxy primer , then bottom paint.
There was one spot on the front of the keel , below the new/old glass joint wich had been partly hidden in the sand in front of the keel. It was sanded out then I used epoxy filler before the primer. I didn't even have time to paint that spot before launching if I were to catch my flight home.



The sailing to my buddy's home harbour took a bit longer time than I planned. Little and no wind , and against the wind when there were wind.
I got time to take a couple of pictures:

I struggled to get decent shape on the main, but after this pictures was taken , I loosened the so-called outhaul (fence wire!!) and got somewhat better shape on the main. Anyway , this rolling-reefed main thingy got to go! I got my eyes on a used sparcraft boom with proper outhaul and two reefs, + a profurl for the jib. Just hopes the sick-pay compensation arrives before they sell.
Another pic:


I'm going back south in a week or two to install some engine , electric or outboard, and sail it about for some days. If all looks good , I'll head north along the coast soon.

I Think I should say that the reason I skipped the finish work was because of the motorcycle accident + the fact that the boat had to be removed before july 1.
I'll haul the boat next winter, check my repairs and do the outside finish.

I'm currently at home , just planning the next steps.
I'll sail her a bit before planning new sails, But getting a new boom with reefing lines and a outhaul is a priority. a Roller furling headstay is allso on the list.

Other stuff to do:

Motor install. I'll probably sail it home with an outboard. The electric engine is the main showcase in this boat and it has to be a neat , professional install.

Deck to hull joint. There is at least two leaks on the port side , so the teak rail is coming off. most likely permanent. Then I'll take it from there..

Interior. Major cleanup, New hull liners all over, a few meranti details to replace, hand pump toilet with waste tank, and a stove.

A lot to do , and the guy who described sailboats as " a hole in the ocean wich you throw money in" was spot on.

Hi,

Very sorry to hear about the dog and the accident. Hope you are all right now and looking forward to a sailing summer.

She looks very nice on the water. That's a big overlap genoa there so make sure you will find yourself a smaller, strong jib for those windy days.

Try not to remove the rail (permanently) - you want a place to brace your foot and a plain deck edge is no good at all.

If your current boom is OK, you may be able to convert it to slab reefing quite easily. You may also be able to convert the mainsail to slabs. You have a cross cut main and that's easy to modify.

Can't see if you have a vang there. If you do not have a vang, get one.

Nice pictures, out here where we are (Canary Islands) one never gets to see water this flat - if there is little wind, there is always swell.

Big hug,
barnie

Congratulations for getting her this far in such a short period of time. It looks great and I know it must feel great. I waited 1 1/2 years before I could get my boat launched.

Looking forward to watching it unfold as you progress with your project.
