probs with the 4.5 Centaur from a brief survey that make 4.5k hopelessly optimistic - such a shame as the inside is fantastic
maybe she is a scrapper
1. The Hull
On examining the hull below the waterline seven areas of paint coverings were removed
down to the gelcoat. In all of these areas blisters were noted. They are about 5mm in diameter.
When spiked a dark, strong smelling liquid seeped out. This was tested using Litmus paper
and found to be acidic indicating that they are Osmotic. The laminate behind these blisters is
still hard and the hull currently is not in a seriously unstable condition. However, the osmosis
appears to be widespread and will inevitably require remedial treatment in the near future.
Best practice would be to have a new osmosis treatment carried out as soon as possible. If it is
delayed it should be clearly understood that the longer remedial treatment is delayed the
greater is the risk of serious laminate damage occurring.
There is some impact damage to the hull found on the starboard side approximately 1.5
metres aft of the stem and 70cm below the waterline. This consists of a crack approximately 8
cm long and other smaller cracks in the adjacent gelcoat. When pressure was put onto the
gelcoat, water oozed out. It was not possible to gain access to this area internally as the fitted
water tank obscures the hull here, but bearing in mind that Centaurs are solidly built it is
unlikely the crack will have penetrated the hull. However there is a small crack in the
bulkhead bonding aft of the water tank locker which may have occurred as part of this
The recommendation for both cracks would be to grind back to solid structure and laminate
new material in place.

S u r v e y s
The rudder has suffered a significant knock aft and the rudder stock is bent. In turn this affects
the steering controls in that the tiller cannot be pushed fully to the port side. Seen internally
the fitting at the lower end of the rudder tube is very corroded and it is suspected that this has
been damaged and water is entering via the bolts. The recommendation would be to drop the
rudder and examine all the component parts. It is not possible to straighten the stock and
therefore a replacement rudder should be budgeted for.
3. Keel Support
Centaurs are known to have structural problems relating to the keel root areas and most have
had remedial work to reinforce the laminate around this area. Seen internally the port keel has
been reinforced with an extra web over the keel root and extra layers of laminate. However,
there is a crack in the bonding to the aft web on this side, which requires grinding back and
laminating to ensure the integrity of the original design is retained.
