Diving Seasons - What to Expect!

Monitor your boat from the day we clean onwards - See how fast the growth accumulates!!

Summer Madness:
April 1st.- October 31st.
"Hard Growth"  colonizes in areas of your boat that have little or no anti-fouling paint and spreads
rapidly and in as little as two weeks affects performance. The maturing Coral Worm grows rapidly.
By week 3 & 4 the boat will be sluggish in the water, throttles are simply advanced to compensate for
the speed loss. Increases in RPMs to attain speed in spite of fouling will create a great deal of strain
on the engine, demanding that it work progressively harder. Generally, this adds to fuel costs and
reduces the life of the engine and other moving parts.
Newly painted boats will suffer on unpainted propellers, hampering performance.
Do not underestimate the seriousness of this problem. Get your vessel cleaned at least every two
weeks during the summer season.  If the bottom paint is good we will perform a 1/2 clean on all
unpainted areas - Props, Shafts Intakes, Speed wheels, Trim Tabs and Waterline at only 1/2 the
regular cost.
More frequent cleaning is lighter on and good for your paint.
Always call before a trip and go with a clean bottom.

Unfortunately  Out-Drive paint is very thin, weak and cannot access enough coverage of the intricate
underwater areas , therefore summer growth is always bad. If your hull bottom paint is good we can
exclude that if you so wish, and perform a 1/2 clean - Out-Drive, Trim Tabs, Intakes and Waterline at
1/2 the regular cost.
All boats with “Poor” or “No Paint”. See your Service Report, as they require 100% scraping of the hull.
Winter - Rainy Season - October - March 31St.:
“Why is my boat looking so dirty”
The winter rain flushes the streets and fields allowing filthy water, bacteria plus a high nitrogen
content (from agriculture use) to enter the marina, unsightly waterline scum will attach to your boat,
but worse still, the waters new nitrogen content fertilizes the algae causing it to bloom out of control.
Now, the stubborn algae, embedded in the waterline and trailing edge areas around your boat,  will
grow back in days after cleaning ...Try a mid-cycle waterline clean!
Stern/out-drives  will continue to be cleaned on the 2-week cycle due to this continual problem
(unless you inform us otherwise).
Remember, we can only do so much. Nature takes its course, there comes a time when it’s your
decision to have a clean or dirty vessel.
