  1. Not sure what the USCG regulations are but consider the use of some solid piping where allows. It's amazing how fuel smell can build up in confined spaces (permeate through fuel hosing and less than perfect fittings). Only use the USCG rated fuel hose. Personally, I used a plexiglass hatch porthole so I can see what is going on in the cofferdam for the fuel tank.
  2. Interesting read. Passion (boat building here) keeps us all young and motivated
  3. Thanks Justin! It sure is a journey if lots of time love and care is put into a build (such as your project and some of the other build on this forum) I still need to finish the model but it will be done soon. I have had the boat on the water for several months now and have had 3 offers to purchase it. People stop me at the gas station, the boat harbour, out fishing, and even knock on my front door to ask if they can have a look over it. I never intended it to be anything more than a tool for my fly fishing and family adventures - so humbled by all the compliments. Graham is certainly a talented designer and am greatful he bring designs like this to hobby builders such as ourselves. Building a boat is so rewarding, is certainly trumps any other achievement ive personally achieved in my life like university/masters degrees etc. Look forward to following others builds such yours now
  4. Are you going to leave the outer hull (topsides) timber finish? Might look nice. May i ask how the topside sheets are joined. Finger or scarf joins?
  5. As promised, my particular performance specs incase anyone is interested / building an OC20. Motor: Yamaha 150hp XCA (2800cc) Digital Electric Control Prop: Yamaha Reliance 3 blade Stainless 17m 14 1/4 Trim Tabs: Bennett Bolt 9x12 Crew: 3 Fuel: 150 Litres WOT: 40 Knots at 6000RPM Cruise: 20-25 knots at 3400-3800rpm Fuel: 17-20 Litres per hour at cruise Just did a 150km round trip to the top of Fraser Island and we only used 74 Litres of fuel total.
  6. Thanks Thrillsbe! having heaps of fun with her
  7. Thanks Lotus! Once engine has been run I shall report back with some figures
  8. Thanks Graham. I had no idea of your ties to Brunswick Heads! Such a beautiful place, and still a sleepy little town (which I hope never changes).
  9. Many thanks Ken! yes looking forward spending lots of family time out on it. Thanks PadrePoint!
  10. Hi all, Might be time to bring this thread to an end.. After waiting patiently for 4 months, the motor finally arrived this week (Yamaha 150hp DEC 2.8L) I have to admit I was a bit nervous about the sea trials given the amount of hours which went into the project. Despite a few minor setup/teething problems (to be expected), she floated perfectly on her lines and went like a dream! I am so happy with the performance. A well mannered hull with such a dry and smooth ride. At-rest stability was great as well. All the hard work was suddenly forgotten after seeing my wife and young sons face light up we put the throttle down - which was approaching 40knots on the yamaha gauge! He has been a champ helping me out from time to time on the project and was 4 years old when we started (now 9 years old). The only regret I have about the project is not finishing it in time for my father to see it (passed away mid last year ? Most of all, I wanted thank to thank Grahame and the B&B team for such a great design, and plans which were so accurate and simple to follow. You are a very talented designer. If anyone is interested in the performance specs with this particular motor setup, let me know and I can post here once the engine has been run-in properly. Thanks for following the build and anyone who offered advise along the way. Regards Lenny Pic of launch and Yamaha tech, Brunswick River, Australia
  11. Thanks Riggs. Looking forward to seeing yours finished off too
  12. Thanks Ken, yes, you know the feeling
