  1. Ha, I had my popcorn out waiting for these comments A reminder that the inside helm / forward cockpit mix is a concept designed to facilitate short handed cruising. Gunboats (most actually) have raced like that but it is obvious that being aft and open to the breeze it better for ultimate performance racing, hence all the tiller upgrades over the years. This owner is used to monohull class racing, holding on to a carbon wheel at the back of the bus, so think of this as a bit more complex solution to the tiller problem! Honestly it felt great, very light, with a curved back su
  2. This is terrible news. My thoughts and love to all those involved. Let's give them some time to take stock and give feedback on the event when they are ready, without jumping to any conclusions. This is a bad day for anyone in the multihull world and indeed any sailor!
  3. Apologies for the slow replies we've been doing a lot of sailing on 68-03 over here, in lieu of the Cannes Boat Show. For prospective clients it's been much more valuable than a show visit, of course we would have loved to show the boat to more people. Next year, I hope life is more back to normal! I'll answer some of the questions with a little info - forgive the cloak and dagger but this is early days and we're trying to be respectful to the owners with whom we are still working through some of the steps of the project. Ah ha! It's finally happening - aft helms on a Gunboat.
  4. We've quietly been working on something new the past few months. Watch this space!
  5. Ha, no of course if you're going fast then there will be a lot of apparent wind, let me clarify that statement: Because you have a wall behind you and you're tucked into a recessed hole in the boat, it is less windy that the equivalent exposed aft helm. Even on Allegra (APC Irens 78 footer), which have done an amazing job of designing a sexy and functional aft helm (They still have a forward cockpit though!), they put up little spray dodgers for sailing offshore - they reckon it is just really tiring without it.
  6. Ah ha! A forward cockpit thread! Haven't had one of these for a few years, or... weeks. My ears were burning, so happy to delve in a little. Firstly, I am by no means a forward cockpit convert or evangelist, just happen to have built a lot of boats with them, as well as aft helm boats - short answer is it depends what you want. However, I think the idea of the fwd pit/outside helm is often misunderstood. I deal with this question 50 times a day at boatshows and literally weekly online. People often think that interior helm boats are designed with the helm inside as the driving desi
  7. Sorry I can't share that info - mostly because it is completely irrelevant without perspective. We do a lot more outsourcing in Europe compared to other countries so our "make vs buy" strategy means our hours would be less than comparative yards elsewhere. I like to say we do in house what we are really specialists in, if someone can do it better and more affordably than we can, we should seriously consider outsourcing it...*** as long as there isn't an IP conflict. These boats are semi-custom, high tech and take tens of thousands of hours, is all I can say. Here's a photo from 68-01
  8. Rig is the 'regatta' rig, which means 29 meter, rotating. Sensor wasn't on yet in the photo. We were skimming along after 4 hours of seatrials, everything is just working fantastically. We not only have ultimate confidence in structure and systems, we also have mostly the same team - so everyone knows exactly what to do and when to do it. There is the usual list of things to tweak and sort out, but I'll have that for a first weekend of tests any day! Pic sidenote: We put some batten tension in on Sunday morning to get those wrinkles out the main.
  9. Thank you! I Cannot begin to explain the efforts by the whole team and partners, from Lorima to North to Lewmar to Rigging Projects, from Cariboni that were in the Italian epicenter of the pandemic, just to name a few. Everyone juggled so many balls to get everything here on time. We had to keep the builders safe, so we had only one person per area in the boat, which meant two very long shifts for everyone. Our paint team are mostly made up of Polish guys - more like super-humans than guys - and they went home during the lockdowns, yet returned sooner than we originally expected, which made a
  10. We had Goiot in the office on Monday - to be clear this is for a square hatch, not for the hatch shown in the image. It is the 49.42. As I was explained: To be more technical, the square one only has dogs on one side, so the acrylic can shift on the hinge side. the round ones have dogs almost all the way around, there isn't a way the acrylic can shift, so we are safe. If you have the square hatch, stop sailing and contact Goiot or at least make a plywood cover or emergency stopper for the hole immediately.
  11. Someone commented "Lenny Whitelum" L O L
  12. Happy New Year everybody! Thanks for the support, critique, debate and for just being interested over the course of the project. 2020 here we go! Check out the last update on the Gunboat 68: https://mailchi.mp/gunboat/gunboatnews-dec2019 I've taken some screenshots of the meaty bits below. A few general thoughts - the first 2 boats of a series I generally call prototypes as the second doesn't have the time to take all the production lessons from the first. We're now into "production mode" if you can call it that for these boats. It means even if there are changes to the boat,
  13. Nope! they are custom designed Carbon seats, quick release bases and the seat can rotate. Custom square-to-round style carbon tillers. We still have some tweaks to do on Condor, but getting there.
  14. Gosh guys, thanks. A couple of years in china will ram that patience into you good and and solid. No cliches intended but I am really just a small part of a big team, long ago I realized I am not VERY good at anything, but pretty good at a lot of things so I try to just help all the guys smarter and better than me do their jobs as best they can. Some amazing people here, they are killing it. Lots more work to do and improvements to make. No rest for the wicked!
  15. Look guys and gals, Gunboat aren't involved in the "soma project" so really can't comment - there's a thread for that if you feel like it - what I can do is stick to the thread and update you all on the progress at the Gunboat 68 factory! GB6802 Dash has been back in the marina for some final hitlist items and leave for their crossing next week. GB6803 Deck was dry fitted GB6804 Was demolded and... Starting GB6805 in a couple of weeks once the mold is prepped! Check out the link for more info: https://www.gunboat.com/gunboat68-on-a-roll/
  16. This is a good bit of boatbuilding debate, as pertinent to crash protection as Kevlar vs Carbon is. Firstly some info: Stitched fabric is a bit lighter and stiffer than woven fabrics because the woven weave absorbs slightly more resin and the "rovings/strands" of material need to go up and down through the weave, where a flat stitched fabric has strands that are completely straight. However on cruising boats we have always used a woven fabric as the first layer down on the mold because, apart from some sanding-and-painting benefits and it printing less, it holds together in a crash. If y
  17. Everything you guys say is absolutely right - Kevlar is of course better than Carbon for crash resistance - they make bullet proof vests out of the stuff! Our conclusion was to use the minimum skin thickness requirement to benefit performance while understanding our heavy skins already gave us a huge margin of safety for impact strength, we then analyse what the crash event is doing. The vast majority of times it is from the front onto the bow or foils (and we discussed this in this thread before so please go back to check that out) - so we do a 4 level of safety which I will reiterate v
  18. Ya got me mate. They aren't the highest energy and not the final solution to this regen story but they work well, completely detachable and serviceable and don't hurt the boat if the get hit or if they break. A safe go to add on option for diesel propulsion boats.
  19. A number of years ago hybrid laminates were all the rage - 900grams of carbon and then 300g of kevlar or eglass. I can't dispute that the last 300g in kevlar would handle dock-rash better, but it is absolutely just going along for the ride. VPLP told us why put something in there that doesn't DO anything to the stiffness of the boat? It is like making a rope out of Dyneema and Polyester strands - the Dyneema will take all the load to failure before the PE even gets close to its max strain. So on the Gunboat 68, because in essence it is already beefed up by minimum skin thickness requirem
  20. I'll wade in, why not. She has so much power right now I don't think she even gets it. People are loving the young person scolding adults idea - makes us all look like fools because she is willing to say the things nobody else is willing to. She doesn't play by the rules. But - I thought her basically crying whiny speech to the UN was almost to the point of being rude, she was not showing maturity in controlling emotions. I understand she is still a child and it must be hard, but it she wants to make a real change then you need to deliver the message to the leaders of the world with matu
  21. Hi Wess It depends on the size and purpose of the boat, even in CE you get different design categories that drive structural engineering. I can tell you that our size of boats, built to CE, have to have 1200g/sm skins (that is 1.2mm) on the outside skin. I would never want to go under 1000g for real protection for a 'big' cruising boat. If your buddy has 300g skins, that will hold the boat together, but impact or dock rash strength is very little, so he better baby that boat as much as possible, because: sh!t happens and that is why CE (Really, ISO Structural Cat A) have these rulebooks,
  22. Hey you guys ARE smoking something - love these ideas! Yeah the glue down panels I am guessing lose 10-15% compared to raised /cooled panels, but they are walk-on and super easy to install and integrate. Water cooling in roof is doable, you are on a sandwich panel one side of foam, so you'd need to prep the water grid recesses in the mold before starting the roof. These will make the roof a lot heavier not even to speak of the water cooling system weight. Then the install complexity and the risk of leaks. Is the cost and sailing performance loss worth a 10% gain on solar? I'd rather spend that
  23. Hi everyone, forgive me for the blatant marketing blurb, but you may find it interesting! If you'd like to see Dash or Condor they will be at boatshows next week: Dash at Cannes,France from 10 - 15 September and Condor at Newport,RI 12-15 September. For those interested you can read a little about the Dash seatrials (and first cruise!) and latest yard news here: https://mailchi.mp/gunboat/gunboat68news-sept2019?e=d35c5fd16e
  24. Hello Lurker19, congrats for not lurking anymore! To be clear it is no secret V1.0 of Gunboat hybrid systems back in 2012 did not work very well, but that was seriously bleeding edge of the sword science project stuff. Moonwave as she is right now with a Torqeedo Hybrid system is seriously impressive. I've been on board to see it myself and we are in close touch with them. The exterior designer of Moonwave was on board a while ago for a week's cruise and apparently they didn't burn a drop of diesel. (Note - no airconditioning) You're talking about a parallel hybrid and there
