What is the general feeling on the market for 30' sports boats

If you were using the boat at sea, i think you'd find that you wouldn't be cruising at 29 knots so much, unless you really really like your back specialist.

She doesnt slam too much unless she lands heavy on the chine, which isnt too often. Even with the 1m chop we experienced on the way back from Wells she was pretty composed at 25 knots with only the occasional hard landing.
 
Not so. The KAD32 has steady fuel consumption (measured in mpg at around 4mpg) from 20 knots to 30 knots so there is no benefit in cruising slower.

We have found that our S23 is happier being pushed that little bit more.

Would be interested to see the graph.

You should find that by backing of from WOT by 10% will all but half the consumption and in fair conditions drop performance by about 20% to 30%.
Further throttle reductions will lower fuel consumption a lot firther, but now result in bigger drops in speed as the boat begins to drag more.

Not as familiar with the Kad32, but the 43 uses something like 12gph at WOT and about 6.5 gph at 10% off WOT.
The Kad300 goes up to about 14gph and 7 gph respectively.

At a guess (a total guess) the Kad32 will be about 9 gph at WOT and down at 4.5 to 5gph at 10% off.

Working in MPG on a boat is a very dangerous practise if you don't take into account the conditions. Most regular cruisers will be working in GPH or LPH (for a given RPM) as the distance achieved can vary so dramitically on any given day.
 
Back to the OP.

I wouldn't say that you're boat is underpowered. We cruise quite a bit, often in company with our local berth holders assoc. 21kts or thereabouts seems to be the speed that most members seem comfortable to cruise at.

Good luck with moving her on.

27-28 knots isnt wide open throttle and we rarely if ever cruise at wide open throttle other than to really stretch her legs for short periods in good conditions. We tend to cruise for longer periods at about 3200rpm whereas WOT is about 3600rpm.

There was a section in MBM (in the questions column) not too long ago featuring the fuel consumption of the KAD32 and it pretty much confirmed what we had already found out that there is little point with these engines in slowing down, you will still use the same amount of fuel to get to your destination, but you will lose drinking time at the other end.

As a general rule we do work in LPH however for this exercise it was easier to work in MPG. At full speed 30 knots she uses about 7 GPH or 31.5LPH, backing down to 27 knots and that consumption goes down to 6GPH or 27LPH, backing down to around 25 knots and you get around 5GPH or 25 LPH. It is a fairly smooth rate of consumption hence why there is little point in slowing down unless necessary because as the fuel consumption goes down the time to reach your destination goes back up.
 
I have to admit that I find 2800rpms and 20kts to be a very relaxing cruise speed.

Takes a bit longer to get there, but setting out a bit earlier solves that :)
 
Firstly I think you really should be listed on here...

Personally I would also look at the price. A 2005 S29 has just been sold for 77K (and I am fairly sure that it had the D3 190's with electronic controls - although I may be wrong).

My personal experience of buying Sealine boats (I have one and I am looking to upgrade to my next in the near future) is that I would always look at the Sealine used boats on their website - I would also use Ancasta as my broker (they list you on Sealine's website as they are Sealine dealers).

I have no connection to them - IMHO I just think that they could probably help you sell your boat for a realistic price.
 
i would love a sc29, ive got a s28 and last year came came close to changing it until I found out about the d3 problems and wintessed them first hand sorry to say its a real shame but i cant see me ever going for one, unless they did a kad32 version in the early days. if you dont need the money, hang onto it and enjoy it
 
BTW MrD....I am still waiting for that Solent invitation :D


I wanted toinvite you this weekend but hadnt seen you post for ages , are you hiding in the ECF ?

swmbo couldnt make it this wekend so Im single handed (daughter sometimes helps and sometimes decides its time for a strop, I just hope we back back before the wind picks up tomorrow , P360 berthing is borderline for single handed in anything above a 5.

How about a link to your boat add :)
cheers
Pete
