Just had my pre purchase survey done on "my" 1989 Prout 33.
First things first and credit where it is due, the surveyor, Martin Evans, (shipshape @ ntlworld.com) has done an excellent thorough job and I recommend to him anyone. I was frustrated by the fact it took 6 days to get a copy of the report but when I see the detail I can see why.
Overall the results of the survey (24 pages) were very enourgaing and confirmed our own impressions of a well looked after vessel but there were some things of note. I have phoned the Martin and talked through these points and he confirms that there is nothing dramatic here but I would welcome the views of the forum. The current owner is currently reviewing the survey but has made some noises to the effect that all of these are trivial and don't need any attention now/warrant a price negotiation beyond the pre survey price argreed. I welcome your thoughts...

Rudders
Both rudder blades had a history of repair at the time of the 1998 survey. In course of the current survey they were found to be in satisfactory condition, though as is commonly found on rudders of this construction moisture readings were appreciably higher than those on the hull (at 60 - off scale’ on Scale 1 of the Tramex meter, 18 or higher on both scales of the Sovereign meter for comparison). Additionally one relatively small blister was found on either rudder blade and it is probable that more could be found if paint coatings were removed. The blisters which were seen were as follows:
• Of about 6mm diameter, on the outboard side of the starboard rudder 195mm forward of the trailing edge and 320mm from the lower edge of the blade
• Of 3mm diameter on outboard side of port rudder, 15mm forward of the trailing edge and 345mm from the lower edge.
Recommendation – Although the blisters seen on rudders are clearly osmotic in nature (their cavities containing fluid having a pH of 3 (very acidic) as measured using indicator papers, hence presumably established for some years) they are not of structural threat to the hull and no action other than opening up these blisters, flushing thoroughly with freshwater, drying then reprofiling with an epoxy-based filler is considered necessary at present, together with routine monitoring of condition in future (there currently appear to be no centreline splits or other problems jeopardising structural integrity).
LPG
Two 4.5kg butane cylinders are mounted in recesses within a self-draining locker beneath the foredeck...
Valves are fitted on either cylinder, then short lengths of flexible gas delivery hose (to BS 3212/2, dated February 1988 and January 1995) connect to a common pressure regulator from which adequately-secured copper gas delivery tubing leads to appliances ....
Recommendation - Renew both lengths of flexible gas delivery tubing as routine procedure on grounds of age (precautionary renewal now required every five years), using recently-manufactured tubing to BS 3212/2. Work on LPG systems should be carried out by a qualified gas installation engineer.
Heater
An Eberspacher D3L diesel-fired cabin heater (of 3200 watts nominal maximum output) is fitted within the engine compartment...
The heater was seen to operate, though was reluctant to ignite until it was operated with the engine running (hence alternator providing good battery voltage) and once running properly it also cut out without being switched off.
Recommendation - Poor starting is common with this type of heater when battery voltage is low (ignition is by means of a glow plug), but once ignited it should keep running without problem. Carry out further testing to confirm that operation is not optimum, then obtain advice from and consider having unit serviced by a competent technician.

I have seen many posts on the Eberspachers and similar issues. I know this is not uncommon but they of course they should work if serviced/maintained correctly.
