Just wandering what size you feel would justify the additonal expense of a diesel engine.
Size is not the only thing you must consider but also what is the main purpose of having a diesel boat (rib)
Do you just want to go out ever so often for a spin to Cowes and back or serious ribbing like a weekend trip to France or the Channel Islands. If the latter then yes a diesel engine is the way to go
I hv a 6.3 rib with a Mercruiser 1.7 TDI and since a lot has already been said about this engine I suggest you do a search and read some of the previous threads and learn what has been already said about this particular engine and set up.
I keep my rib in Littlehampton and frequently venture out to Cowes/Yarmouth. The cost of diesel for such round trip is only about £20.00 (this is a distance over 80 miles)
Only last weekend I had a conversation with a chap who has a 6 mtr cabin cruiser with a Volvo Penta 140 HP petrol engine. He told me a trip to Brighton and back would cost him about £ 60.00
He also said he would have liked to have a diesel as this would allow him to go out more often and even make longer passages
