Gulfstream Owners:
I just had my Gulfstream patterned/templated (electronically) by Gator Step. They have not installed it yet, hopefully next week. If interested, they can now have the Gulfstream template digitized and can save you time and money. I believe they can ship the finished product to you for DIY install. I'm fortunate that they have a regional office/production facility about 1 mile from my house.
I will post pictures here once mine is finished.
Gator Step seems to be a great product. Very similar to SeaDek, but perhaps a bit firmer. One buddy just had is Riviera done by them and it came out incredible. (I have no affiliation with them).
One consideration: They say plan on a 5ish year life span., but You can get much more life if you keep the boat covered. Also, darker colors can get hot under foot, so you may need to water/cool it down occasionally on hot days.
If interested, send me a PM and I can put you in touch with the dealer that has the Gulfstream pattern.
Finest Kind: Yours looks great!
