I cut out 2 bulkheads today so I guess I’ve officially started my build. I bought the plans a couple weeks ago and I have been gathering materials. I have a couple questions about the plans. Am I correct in assuming bulkheads 1, 2, and 3 show the upper and lower part on the drawings together, but I build them in 2 pieces? Also, in Brian’s build blog he mentions there is an option in the drawings to make a curved front for the cabin, but I don’t see it in my drawings.?

Thanks,
Mark

Hi Mark

Nice to hear that you have started.

When you have made the bulkheads BH2 and 3 to the sheer height, it is okay. There is enough gluing area for the beams without the upper pieces for the beams, Figures 10 and 11. There is no drawing for a curved front.
Principal, I am against it. The shown angled lower front makes the area less prone to wave slamming.

Keep us informed about your progress.

Hi Mark, I'm pleased to hear there is another 480 on the way. it is a great little boat for minimalistic cruising, very dry to sail and a lot of fun. Just regarding the points you raised, as Bernd mentioned the upper sections of the bulkheads are made later. It is useful to transfer the markings for centre line and bulkhead locations to to upper side of the deck panel so you can find them after the hulls have been assembled. As regards the curved front, I asked Bernd specifically for some ideas for a curved panel as i so liked the same detail that is on some of his bigger boats: the KD 860 etc. He sent me a couple of drawings but I had to work out how to do it myself, as per my blog. I wish I had taken more photos. Anyway i assumed at the time that Bernd would include the panel in future plans but I did not realise he was against such a detail fot the reasons he noted today. Personally I have had zero problems with slamming, perhaps because I sail with never more than two up, only day sail, and only sail in relatively sheltered coastal waters. I would be terrified to make such a journey as David Thatcher completed in his Eco 6, basically off shore at times with the potential for huge seas, Mind you he is a very experienced sailor.??

You can pm me if you like, maybe I still have the drawings for that panel if you are keen to attempt it

Bryan, thanks for the info. I have read your entire build blog and found it very helpful to see the parts in real life vs. just on the drawings. This is my second boat build so I am not a complete beginner, but not far from it. I do like the curved cabin front you built on yours. I shouldn’t be sailing in any more than 1 or 2 foot chop so I don’t think slamming would be a problem for me either. Did you make sure the platform you built the hulls on was dead flat or was close to flat good enough? I ask because I don’t have a jointer so if I need to get the top of the build surface flat I will need to do it with my circular saw and a straight edge.

Thanks,
Mark

Thanks, Bernd. I’m excited to get it built and do some camp cruising with it.

Hi Mark!

The bulkheads for the Duo 480 adventure are also ready, but till today, it was really cold at the west coast of Germany, now it is the first 10 degrees above thero day:)

Cheers Harald

Oh doG no! (On the saw/guide front..)

I see that ?bulkhead 2 through 5 outside edge is parallel to the centerline which makes the side 90 degrees to the deck. BH 1 the center line is 11 mm closer to the outside edge at the bottom. So it appears to me that the outside tapers in slightly towards the bottom unlike the other bulkheads. Am I right about this?
