4.2/40hp to 4.7/60hp...much difference?

I have a zodiac pro7, 4.2m with a Suzuki 40 (4 stroke) and was wondering about trading up to the zodiac pro9, 4.7m with a Yamaha 60hp (4 stroke). Would I see much performance increase? I get 32mph at the moment but the ride is a bit choppy in anything other than a flat sea. I have seen a 4.7 and it seems to handle the rougher water a lot better. Would that 0.5m and 20hp make that much difference? Thanks for your thoughts on this.

I think it would but are we talking a big price differential.

Depending on the price determines if its worth it or not.

true Biggles. By performance, I also mean ride quality and safety. I fancy taking my rib down the Tees from Stockton and into the North Sea (on a good day), and out around the south west coast of Scotland so I was keen to hear from anyone who has more knowledge than me about the difference that 0.5m in size would make to the ride. i suppose a 60hp on a 4.7 would give the same sort of speed as a a 40hp on a 4.2.

Waa Hey. I was tooling around in an 11 metre thing made bu quinquarrie (not impressed by the way() with rwin 250's in that sea in some big waves. I was doing Standby work at Sunderland and needed two take the boat for a decokeing run, I remember thinking how fantastic it would have been in my Avon 4.7 (which I foolishly sold) I think the Zodiac and Sea Rider are quite similar in Hull shape.


The difference in handling and sea keeping between a 4 and a 4.7 is surprisingly large. get a sea trial and find out for yourself the extra 20 Hp will help flatten the sea and compensate for the extra beam of the 4.7 I'd advise footstraps

good luck
