Fairline Targa 30 Survey Report

Hi Jimmy , it's not particularly a speed issue though it's down a couple or knots.
The issue is I could not read the correct rpm attained because the rev counters don't work correctly, for example a no load max speed should read 3900/4000 rpm , it read 2000 on the port engine , I carried out a couple of readings with my hand held tacho which wasn't easy bouncing around to get a reading as I could not get into the engine bay as it was too dangerous , this model is a baby targa 40 with a sun pad that lifts to gain engine access . The alternators feed the rev counters with a pulse , as their both after market models there clearly not correctly matched so there is either an issue with the code settings on the rev counters or the alternators are not giving the correct info.

Evening Paul

Gotcha, so you can't tell if the props are right because you can't tell that the engines are making WOT because you can't get an accurate rpm reading because of the alternators. All understood. Tricky problem to solve, in context. The obvious question is - why hasn't the boat got OE alternators? Cost saving? What other maintenance items are wrong for the same reason?
 

So, taking my experience and the experience of the others that contributed to the thread I linked to above, a T30 with A7's running well should be good for 37-38kts. If the boat only managed 32kts on the sea trial something sounds amiss to me.

I would start by insisting that the current owner has new props fitted, the bottom is jet washed and the water tank emptied to see how fast it will go on a second sea trial. Try and get a calm / flat day and find someone who knows what they're doing to trim the drives and the tabs (not that it made much difference to me).

If the seller refuses to co-operate then you'll have to take advice from Volvo Paul and/or the surveyor as to the likelihood of it being a prop issue then factor this into your negotiations. all depends if "you're feeling lucky" and your appetite for risk!

Marine Sales Poole now defunct re profiled props several new boat that were running with heavy loads bought the revs up and also took to 36 knots do not have any further details but may have been reduced diameter
sorry
 
I am just back from the second sea trial after the owner had his engineer fix the rev problem. During the sea trial both the port and starboard engines reached 3900rpm, how ever the starboard engine reached it a lot faster and when past 4000 rpm, any ideas on what the problem could be?
 
also the starboard throttle seemed to go a bit further than the port side, is it possible the throttle cable is worn on the starboard side?
 
Lack of clarity here ?
1st sea trial rpm via Volvo Paul was 2000 due to aftermarket replacement alternators . 32 knots @ WOT
2nd sea trial rpm 3900 and even 4000 ! on the tachometer,s speed the same 32 knots @ WOT

What's changed Is the tachometer readings - that's all .

Until strobe tested its all meaningless IMHO .
 
Yes Pete I bought her. Took four days to sail her from Southampton to the my home marina in Bangor NI which is about 20miles from Belfast.

A great journey home, that had only a few minor issues along the way....broken alternator belt on day 1 with no sight of land. Tangled fishing line in props on day 2, with only a cheap £1 retractable decorators knife to cut it free with, which took about 30 mins (I have since bought a Bear Grylls scout knife). Having to cope with really lumpy seas between Padstow and Arklow in southern Ireland. And then on the last leg 1.5m seas almost the full journey home up along the eastern coast of Ireland. All of which the boat coped admirably with.

We have been getting as much time as possible on her before winterising her as well as learning more about boating in general, so have not had time to thank all those on this forum that helped make this dream a reality.....so thank you.

Hopefully I can help others in the future, when I get a bit of experience under my belt.
 
Well, I think congratulations are very much due! Well done on the big crossing back home as well. The forum always likes to see pictures... :encouragement:
