I would cut the brass cube off and use the correct size six point socket on the nut. That will minimize the chance of slipping and rounding the nut off. I wouldn't use an adjustable wrench, especially as the nut is fairly thin.
I measured the width of the stripes and the space between and specified the colours for the multi-stripe roll.
This is how I ordered mine.
2 x 50 Feet Multi Stripe Rolls - Premium Vinyl
1 1/16 Dark Blue
1/16 Inch Gap
1/8 Inch Ultra Gold Metallic
3/16 Inch Gap
1/4 Inch Dark Blue
With the 226 you have the much maligned transom bang cap and associated wet transoms. Unless length is an issue for storage etc, I don’t see any advantages of a 226 over a 228.
I used Gyeon Q2R Marine Polish Step 1 and Step 2.
Next time I will just use Step 1 as I could see very little difference after using the finer Step 2 compound.
I finished with Gyeon Q2R Gelcoat ceramic coat.
There is a lot of choice. The main question is, do you want to store the anchor on the roller while you are underway or will you be putting it back into anchor locker?
