These paints are contrasting copper-based anti fouling paints. They are both recommended for use in heavy fouling areas, and are eroding types, which means that they shouldn't build up in the long term and ought to maintain their effectiveness throughout the season.
But after that the differences are striking: Optima is water based, Cruiser is 'oil'; although both use copper, Optima also uses 'Biolux' a proprietary biocide. Both need two coats but with Optima they can be on successive days, wheras cruiser really needs a mid-season scrub and re-coat.

| I have heard good things about this premium paint from other boat owners so I have been keen to try it. Up until now I have been put off by the cost, but it seems time to see if it is worth the extra and can keep Touchstone from getting progressively more sluggish as the season progresses. The first thing to note about Optima is that it is water based, don't apply it if it looks like rain or you need to go in the water quickly, it will just run off! At 80 quid a tin this is best learnt from someone else's experience. Optima comes as a two-pack, a white base and a lurid red activator. The activator is added to the base tin and stirred thoroughly until it is evenly mixed, then you go away and have a cup of tea whilst the bubbles subside. Then you apply it, a roller is recommended, I used a brush. Being water-based it is thin and quick to apply, covering well. Overcoating times depend on temperature but in May in the UK I really needed to wit until the next day. when freshly applied, it is a violent pink, but it seems to calm down with time and it's underwater (you hope) most of the time so this is bearable. One bonus of a water based paint is that it washes out under the tap, so no expensive purchase of thinners is necessary to clean yourseld and your brushes. Price : I paid £71.97 for 2.0L |
International Cruiser Premium was the same as last yesr.
Price £59.99 for 2.5L |
It is probably worth remembering that I used a brush and a thinner coat of paint would have resulted from rollering or spraying.
Come back next year for the results of this test.
