On sub 25ft sportscruisers the difference has been marginal since the loss of red. If you take into account purchase, servicing, repairs,fuel and depreciation (including finance costs) petrol and diesel are pretty much the same (especially if you buy fuel at Tesco).
But the clue is in the name, sportscruisers are ment to be sporty, 170hp oil burner just isnt enough for anything but cruising, minimum needs to be 230hp, but for decent performance you need 260hp+ (even I admit that the 7.4l 300hp V8's are a bit over the top and heavy).
I have used an Aquador 23 with a KAD 32, great at the pumps, but slow, smelly and smokey.
I wont even begin to justify over 25ft (Possible exception of single Bayliner 285) or twins. Used a twin petrol V6 Regal 2860 for a season, it was staggering how much fuel you had to chuck at it !
But red diesel has not been lost. Our current supplier is charging 88ppl for red diesel and is local to the marina. The nearest source of petrol waterside which is a good days cruising away is charging 157ppl, not too far off twice the cost plus a days cruising either way to get to it.
30 knots is plenty fast enough for the cruising that we do. We also have a KAD32 and it has proven to be nothing but reliable. It is no slouch but there are faster boats around and it doesnt smoke other than a puff at start up when cold. Yes diesel is smelly when filling up but other than that the diesel heating is more noticaby smelly. The KAD32 may not be the quietest of engines but for the sheer reliability of it I think we will stick with it.
