Have you looked at Achilles SSL385 Ceasar Surf Cat and Avon ERB400 also the Arancia 388 and Gemini Surf GRX 400 and the GRX 420
All can operate well with the engine size you talk about ,as for speeds it depends on how much weight you are carrying and the conditions you are operating in but a 30hp is adequate for IRB work and probably the most popular size , Have you approached any dealers in your area to see if they will discount you as you are a Rescue Unit
Surf Lifesaving Association GB favour the Arancia as do the RNLI Lifeguards .
I would look at the other boats as although the Quicksilver is a good SIB I am not sure if it is as tough as some of the other's mentioned if you can afford it go for a SIB made of Hypolon
