When we weighed her all we wanted to see was if she was coming in lighter than expected. I don't really think it will translate into a big increase in speed and fuel burn rates since many factors also come into play but it will help. We did an initial study with 3 power plant options and it was interesting how much more HP was required to pick a few knots of speed. So at this point the goal is to continue to use some composite materials to complete the construction but for the most part we're very pleased that we're lighter. Full tanks on this vessel will increase the weight by 7750lbs. So it should be interesting to see how she performs.
The beam is 16’ with 12’ at the waterline. The generator is a Norpro 12.5K watt unit. I went with Norpro because of price and because they use a Yanmar diesel to power it.
They seem to build a lot of boats out of Alloys in your part of the world. Isn’t sealium alloy the best alloy to build them out of? And if you get 35 knts out of it that would be a fast boat. Good luck on the build. I’m sure the guys on this site would be very interested in seeing that boat and learning more about that construction.
