: sufficient.
: Thanks.

your 2" tape will be sufficient, but it may be the most difficul to install. Strength and bonding area aren't really the issue. What you will be dealing with is trying to apply the tape to a complex curve while folding it in half lengthwise, as you struggle in a tight enclosure.

Tapes are woven with the threads of the material going back and forth from edge to edge, giving a finished edge on each side. This is also called a selvedge edge. The weaving process makes the selvedge edges denser. They will be more difficult to fold and to stretch to get them to conform to complex shapes. Your 2" tape puts the left and right selvedge edges an inch closer together than your 3" tape. If you are going to use tape at all, try using both tapes on the outside of of the boat. Put it on dry, no resin or glue here, just maybe a few dabs of masking tape to hold the stuff temporarily in place. If you have no problem fitting it over the outside then you should be able to get it to make the same bends when it is installed on the inside.

But I suspect you may have tried this already, and not liked the results--'cause you say you are using bias-cut fabric on the outside. The tape is woven "square". Bias-cut strips have the weave going at a 45 degree angle to the length of the strips, and the edges are not bound or woven together. They can move and the strips can be stretched to fit complex shapes. Once. Pull it out of shape and it is a mess trying to get it back to the shape it started out--so try not to tug on it as you install it.

If you think that it is important to use bias-cut strips on the outside, then it will be equally important to use them on the inside. They'll fit into the seams better than woven tapes, and you'll be done faster. You can cut your bias strips 3" wide, and use some for the inside and some for the outside. Put the tapes away for another project.

Just a thought
