Started Fairing the hull(pics)

Andrew, It was perfect until I leaned a little to hard with the sander. I figure when I put on my keelsons and fillet, it will cover any imperfections. Havnt purchased the wood for the keelsons yet. What do you suggest? What type of wood?
 
Now that you mention it, it does look like there is some wobble to the hull along the keel. I woudl put a straightedge along the hull (not the sanded areas) and take a look at it. If it is to be fixed, this would be a good time. It looks liek there is a hook in there, which if that is the case would really mess up the performance.

I don't think it looks like sanding error along the keel because sanding too deeply would expose more plys, which isn't the case in the photo.
 
For me in my area, yes, Kevlar would be overkill. Yes, I have stumps and some rocks but mostly mud. If I was going run a lot in areas of oyster shells, barnacles, etc. I would think that Kevlar might be warrented. Look around at other wood boats in your area. Do they use Kevlar on their hulls? I used 6 oz glass and regular epoxy like on the decks. Over the top of that epoxy I used a product from Florida called 9x-2000 which is an epoxy loaded with teflon and graphite. It was originally developed for the bottom of airboats. Made a real slick surface.

The other thing to consider, and this is only hearsay as I haven't used it, is that Kevlar can be a bitch to wet out so will take longer, etc. There are one or two guys on here that used Kevlar on their hulls but I don't remember who - hopefully they will speak up.
 
What appears to be a wobble is actually more plys exposes on either side of the keel line. I didnt want to even out the plys on the opposite side of the keel for fear I would go to deep. Before I sanded the line was straight and true. I hope this explains the wobble. Am I correct in assuming that the keelson and fillet should take care of this or should I build it back up?

Pete,

We had a discussion on here last week that you missed. In short, I didn't find it that bad to wet and worth it on the abrasion resistance end here in my rocky world. Putting the glass over it wet-on-wet was not my fav though.
 
Aaah, OK. Yep, I was gone last week. I kind of thought that you might have been one who used Kevlar but couldn't remember. I guess my memory of your experience was embellished. I take it that it has held up well? Do I read that right that you put the Kevlar on over the top of the regular glass - wet on wet? That doesn't sound fun at all.
 
Shame on you for missing a week... Glass goes over kevlar, yes a pain to have two layers not fully cured, but I didn't put the glass on until the kevlar was fairly set.

I've put some very large digs through the glass, but the rocks have always ridden over the kevlar. Maybe it would be the same with 2 layers of glass?
 
Keel line before some over zealous sanding.

Charlie...

Slow down. Tod's right. If you have any hull imperfections, it'll be a huge bummer for you.

Take a straight edge, a 36" steel ruler is excellent for this and check both of the hull sides - holding the straight edge with both hands while standing behind the transom and pull the straight edge towards you... and determine if there are any dips/divots. You can fill in the dips with epoxy and the red shizz for filler I forget what it's called.

Have someone else do it for you (slowly and incrementally) and take a look yourself and determine, by eye, if both sides are in 100% proportion.

I remember, they call the red stuff micro-balloons, it sands easily.

I wouldn't do any more work until you get this solved.

For the keelsons, suggest using Mahogany or any other hard wood. I used Fir --- beautiful wood, but NOT tough enough. It's a sacrificial part of your boat. Suggest that you do NOT put fiberglass over it.

May want to look at Poly runners or brass ovals for protection. I used the ovals, and the protection is excellent.

Good luck..A
