One custom item I have never seen mentioned on this forum is custom - color coordinated rope. I ordered 400’ of custom rope from Miami cordage and made up dock lines, fender lines and anchor lines from it. My only complaint was the rope was thicker than ordered making the lines a little oversized.
They look good on the boat though,

FYI - they were slow on delivery, so allow time if any one orders from them. Their “1/2”” rope is way too thick - unless they just screwed up my order. I would probably order the 3/8 if I buy again.
We went a little spend crazy when we first got our Yamaha but we have utilized and feel everything has added to our boating fun. The favorite upgrade however is the Ridesteady without any hesitation we would get that again.
I did find humor in my wife thinking that 5 years in I’m done with upgrades - she is quite the comedian!
