I'm back. I have been doing some additional research and it appears I am reaching a decision point roughly in line with Kevlar methodology for repairing the bottom of my Tatman framed boat (previous discussion on line-x June 6).

I am leaning towards kevlar for bottom. The questions remaining....
What weight, what weave and how many layers? I would like to do it in one layer say 9oz or 13oz but not sure if that is sufficient. I havn't been able to find anything greater than 13 oz. on the web. any info here would be appreciated.
layup...wrap the chine cap or not? If so wrap with either kevlar tape or wrap the bottom pieces over the chine cap? Epoxy the kevlar to the chine cap or........
I plan on putting new uhmw strips over the chine cap again. I had good experience with them in this application...just not on the bottom. I could possibly wrap the bottom kevlar over the chines but just not epoxy it to the chine cap but rather sandwich it in between the uhmw chine cap and the oak chine cap. A 'flap' on each side of the bottom kevlar piece in a sense to wrap/sandwich to the chine cap. By sandwiching vs. epoxy this would thereby allow the chine cap and chine to be removed at a later date if needed and would not expose cut edges of the kevlar bottom pieces but rather the edges would be exposed on the top of the chine cap sandwiched accordingly. But not sure about this idea or not but sounds reasonable. I think the challenge with this dry 'flap' concept would be wetting up the bottom but keeping the epoxy cleaned up that pushes out the sides and keeping it off the 'flaps' to allow them to be bent over the chines. The only other question with this is how easily the heavier kevlar fabric would wrap the chine cap in this application? The last option would simply be to not put anything on the chine cap and only kevlar the bottom and may be a be over zelous with the kevlar but having a layer of it over the chine cap sure sounds like good additional protection.

regarding bottom layup, I plan on laying up the kevlar perpendicular to the length of the boat and overlapping each piece on the bottom approximatley 6". This is primarily due to the fact that widest part of bottom is 54" and most all heavier weight fabric is less than 50" and thereby would still have a 2" gap on either side of the bottom to deal with.

Any suggestions or thoughts would be appreciated.

Thanks,
Jonathan
