It surely looks like a riser hull if I understand the terminology correctly as the centre part of the hull of about a foot or more, is running a bit deeper than the rest of the hull. You are correct. When we tested it the turning of that little boat was very impressive.

I have attached some additional pictures of what I have about the hull on the attached link. https://www.facebook.com/media/set/?set=a.519850781431547.1073741825.100002198882039&type=1&l=d92b222b81 Once we have recieved our own boat I could add more specific pics.

We are located in South Africa and I am not aware of these types of laws here as you described it. Thank you very much for your help and the willingness to share your knowledge. We got onto the demo to basically observe how it is lying/sitting in the water in terms of boyance and nothing about the performance. We have a lot of confidence in the hull design that it would be able to handle rough waters. We also wanted to get a feel on how functional the layout of the decks was In about 3 weeks time we will be starting to setup the boat we ordered with the 70 Yami and will post a picture of it again at that time. For interest sake: Are you a boat dealer or just a boat fanatic that you have so mich knowledge about these things?? Thanks again

Keith I know this is hard to believe but this is in fact a 15ft boat with a 125hp merc on. The people that are doing the marketing on this boat mentioned that they are going to test a 150hp aswell. It is that thing of "the bigger the better". They are however not marketing the boat to be rated with a 125Hp. It is rated for 60HP-115Hp. I am not very good with Facbook and those things but it is the only way I could post some images for you to see the boat. Please try to access the link that should take you to 4 pics of the boat. https://www.facebook.com/media/set/?set=a.519850781431547.1073741825.100002198882039&type=1&l=d92b222b81 Thanks for the information on the Jackplate. This gives us a good idea on how to measure for the correct Jack and offset. To your comment about us taking a ride in a demo with different motor etc. This was the first time this boat was on the water and we wanted to see how it performed with a much larger motor than what we intended it for. Our logic was that if it is handling that weight of a 125hp we would be well setup with our 70hp. The 125 was not completely setup correctly as I mentioned and I think they had the incorrect prop on there (think 22p Prop) which made the performance of the motor questionable. It was also a brand new motor and is probably still running in. Make no mistake that once the boat has plained it was running very well for a small boat but we just thought that in take off we did not feel that spark of performance. In your oinion would you think we would go overboard with a 8" as we saw some similar small boats in Japan with a big body outmount and probably a 5"/6" Jackplate on top of that and it seems to perform very well (60hp Merc)?? We will however utilize your guided calculations to determine the size. Thanks again

Would there be any benifit going for the 8" plate over the 5"?

Ordered a new boat that will probably be ready for delivery in 3 weeks. It is a 4.5meter (15ft) fibreglass bassboat. We are wondering about what size of Jackplate to install with a 70hp Yamaha outboard. We currently have a 5" plate but considering to change it for an 8". The Demo boat was tested with a 125hp Mercury and a 6" Jackplate but we thought the motor struggled to plane the boat quickly. The motor was probably not 100% setup but we thought that size motor should have plained quicker on that small boat We think the 8" Jackplate could help or eliminate some of that. Would our thoughts be correct. To view some pictures of the boat you could Google "Bass Hooker 455"
