“Since I bought my boat new, I have never had a safety chain on my trailer for the bow eye”.
I think the responses above might have missed your point.
You don’t need a chain there because of BassCat’s design with the two rollers where the strap goes under the bottom one and then up to the bow eye. With this configuration, you have a “strap and a chain” all in one.
If I’m wrong, then others will help with this one.
