Ocracoke 256 hull #2 Build

Here's where we are as of today.  I really have been working on this thing even though it may not look like it.

 

When I got back to working on the project I had to fill lots of 36 grit scratches and not quite filled depressions.  Apparently a leopard can change its spots.

After 3 weeks of sanding and 3, progressively smaller spot filling sessions, I sprayed the entire hull with high build primer.

Will sand below the chine tomorrow and then apply finish primer/sealer.  Then on to the bottom paint which will be VC Performance.

So the big day came and went.  The boat is turned over.  

 

Like so many things in our lives, it didn't go according to plan.  My intent was to hook the whole thing to the backhoe and drag it outside, then use the bucket to flip it.  Well the rains came in this week and the ground outside of the barn is mushy (not paved).  With more rain predicted over the following 5 or so days and then a couple more before the ground would firm up, I needed to go at it a bit differently.  So plan B was implemented; manual flip inside the barn.  That caused some rafter clearance issues and some small chainsaw modifications to the roll cage.  Not a big deal just took a bit more time like everything else.  More evidence that a plan never survives contact with the enemy.

Soooo, I'm not sure what happened to my last post.  Was it too risque, with all that boat porn.

 

Anyway, here for  a second showing is what I have been doing for the last 6 weeks... On the boat.

 

Glassing all the little boxes created by the frames and stringers.  I have 22 of 25 boxes done, just the 2 center aft and the anchor locker to go.  I should be working on it right now instead of typing this, but I'm procrastinating.

Steve,

Did you fill the bilge area on either side of the keel? Been thinking about doing something similar on my OB26. Also the area where water can collect at the chine. Any input appreciated. Looks great!

Cheers,Ken

 

I sure did.  

 

Up forward in the storage area i filled with structural foam all the way to the top of the keel.  I don't like small areas for debris or water to accumulate.  It also makes the storage area more functional for me.  I considered doing that all the way aft, but realized that beside all the work and weight it added, I needed a channel for water to run aft and not contact or be blocked by the tanks.  My compromise was to fill with some .750 ply I had as drop from the bracket transom.  So I ripped up the scrap with a 16° miter (except the first 2 or so feet where the keel turns up a bit), fitted it and glued it in.  I really like the result, a 3 inch wide flat flanking the keel giving a nice drain channel and an easy to clean and dry area.  This will also allow the bilge pump to remove more water getting the suction port closer to the bottom.

 

As for the space outboard of the log, I'm still thinking about that.  When I was glassing I realized what you have already, there is no way for that area to drain.  Theoretically, water shouldn't be able to get there, but as we all know water gets everywhere.  The only viable solution for that area that I can come up with is pour foam and glass to create a "water tight" area.  I haven't decided how or if I will address this area.

On filling compartments with foam. Any area where water is likely to run and/or collect that you fill with foam is a likely place for water to find its way into through tiny pinholes, cracks, slight area that you don't glass and resin coat thoroughly enough, osmosis, wrong phase of the moon, etc., Be VERY careful to seal the foamed area VERY well. Years of building and repairing boats has taught me that water can find it's way anywhere. Poured in, structural foam can trap that water against the skin of the hull and cause rot, even with epoxy coating. Maybe. Just enough "maybe" enough that I don't like to use it. I prefer to cut foam blocks to be a loose fit, and ventilate the area somehow. Maybe with a removable access port.

 

Just want y'all to think about it.

Hi Guys,

All of your thoughts are similar to the things that pop into my mind at 3:00am. Give me your phone numbers and I will call you when I can't sleep:). The chine areas in particular seem like a potential problem. Ventilating means air flow (good) but then water gets in(bad). Sealed means no pin holes, or else. I guess you have to pick a path and be sure it is done perfectly. Thanks guys.

Ken

Here's where I am today.  One compartment left to glass, the aft, mid.  Some pumps and valves being dropped from my supplier on Wednesday.  Then I'll poke some holes in the bottom of the boat, move the core away, glass, fill, glass, mount a groco bb-1 and fab a couple pump mounts.

 

Oh, the joy of moving on to something else.  I'll never forget to glass the stringers and frames before installation again.
