merely cosmetic. They do not indi cate a defect in the

boat structure or lamination. Scarab, along with most

boat manufacturers, regard gel blisters as a standard

maintenance item.

The repair procedure for gel coat blisters is similar to

the procedures outlined in the previous section on

cracks and gouges. There is an exception however, in

that the hull must dry out for several days or possibly

weeks before repairs can pro ceed.

and must be allowed to dry longer before repairing.

When the repair is completed, an application of an

epoxy barrier coat should be considered. This will help

prevent the possibility of reoccurrence of blisters. Your

Scarab dealer or local ship store will have informa tion

on barrier coat prod ucts.

NOTICE

DO NOT in stall any item on to or through the

should be used to strengthen any area onto which an

item will be mounted.

E - 4 ANTI-FOULING PAINT

Scarab recommends anti-fouling or bottom paint for

boats which will be kept in the water for extended

periods of time. Anti-fouling paint reacts with water to

retard the growth of algae, barnacles and other marine

growth on the hull. In addition to marine growth, it

offers protection against excessive water pollution.

Anti-fouling paint begins reaction upon contact with

water. After a season’s use or sooner under certain

conditions, the anti-fouling paint may appear to be

dissolving. This is due to the paint’s chemical emis-

sion that in turn retards marine growth. When this



Scarab recommends reapplication of the anti-fouling

paint seasonally. The effectiveness of the paint will be

drastically reduced if used longer. Though Scarab has

found the use of anti-fouling paints provide good

marine growth protec tion in most water, other paints

may be more effective in certain water conditions. See

a Scarab dealer for recommendations on anti-fouling

paint use in your area.

NOTICE

During surface preparation, the hull should be

sanded only enough to remove any for eign

matter, and loose paint. DO NOT sand deeply



could later result. After sanding, the surface

should be wiped with a rag treated with a

clean er recom mended by the anti-fouling paint

manufac turer. The surface must be clean and

slightly rough to ensure proper paint adhe sion.

Prior to application of the anti-fouling paint, the boat

owner may consider coat ing the hull bottom with an

epoxy coating. Scarab recommends this procedure as

a preventive and effective means of controlling

osmotic blistering. Most major anti-fouling paint

manufacturers also supply a line of epoxy undercoat-

ings. Consult your Scarab dealer for recommenda-

tions on epoxy undercoatings.

E - 5 HULL SUPPORT

Proper support of the hull while it is out of the water is

imperative. Due to the design complexi ties, Scarab

does not recommend trailers or storage cradles be

homemade. The boat is a valuable piece of equip-

ment. DO NOT risk per ma nent damage to the hull

structure in an at tempt to save the cost of an ad-
