Hi,
I've only recently got my S24 with a KAD32 and the weather has not been kind enough to let us open her up flat out. I bottled out at 23kts in a F3/4 on the way way back from Portsmouth at night - she had loads of power left but we were getting thrown around so I eased off before the Mrs threw up over me! The "book" speed is about 31 kts (assuming clean hull, no fuel, no water bla bla bla sales pitch) - Realistically I'm expecting 29/30 when I get a flat day to open her up. Maybe this weeknd (well I can dream).

Dave Vinell (dvinell) might be a good person to ask - he has the same as me but might have had a chance to run flat out.

doubt you will get 31 knts with no fuel /forums/images/icons/smile.gif

Now where is that Brendan hiding?

Tee Hee - but you know what I mean. The manufacturers always cover themselves by telling you the top speed but adding the usual caveat that you should only be carrying the minimum of fuel and water - let's face it, most of us are normally carrying more than 5 litres of fuel and half a pint of water......

We have a Sealine S23 with KAD 32 - have achieved 28 knots with full tanks.

Flat out on calm water, trim tabs fully up, engine trimmed to +1, 1/2 tank of fuel, full tank of water, clean hull and perfect props...

30.5 knots

this is completely irrelevant, though, normally we cruise at 20 knots, maybe 23 if flat, maybe 17 if bumpy. Six people on board needs full trim tabs down to plane, but for 2-4 people, no problems...

As a comparison, last season I "raced" my brothers Searay 215EC (Merc 5.0L, 210hp), and although he overtook eventually, it wasn't the whitewash you might have imagined, mainly because of the grip of the duoprop in the low to mid ranges...

20knots is a great all round speed - you need a pretty long hull to cruise much faster without spilling a drop............./forums/images/icons/smile.gif

Agree with you Dave. Low 20's is a comfortable cruising speed and we always drop down to 15-17 when there's a chop - we notice a huge difference in comfort.
I thought I was being a lightweight but obviously you've found it better at that kind of speed too.

Interestingly, I find ours handles MUCH better with a full water tank and full fuel - we've tried both full and empty and she seems to "sit" better with full tanks. Guess that must be due to weight distribution and being that bit heavier she becomes less easily thrown around in bad weather. Don't know whether you found the same thing but I feel more comfortable when she's full so that's how I run her.

BTW, I sent you a Private Message too.

my fuel tank is neutral for weight distribution but the extra weight makes the boat run better into any sort of sea.
Mirror calm it gets a whole extra knot on the last 1/4 tank!
