Is it OK to sand the gel coat (seam) smooth on the bottom of my Tiger hulls and not lose any hull strength? Also, will this make a difference in my racing performance?
Do you have a really prominent seam on the bottom of the boat? I think the early imports into the US had this. I think it may form part of the flange that joins the two halves of the hull and that removing it may weaken the boat. My 2005 boat does not have this on the bottom (it appears to be internal). My friends Dave & Lori Lieb have a 2000 boat and it has a really prominent seam.
Yes my boat does have the prominent seam. I kind of agree with you about the seam being part of the integrity of the boat, that's why I haven't sanded it yet.]
