I've just mounted a pair of new main crossbeams on my Tiki 26, and thought some of you might like to see what was involved.  Zest is one of the Imagine Multihulls Tiki's, built in GRP/foam sandwich…Continue

"For practical info on sandwich panel catamaran construction, refer Derek Kelsall and his KSS system. He started with this type of composite construction almost 50 years ago and has kept at it with updates ever since."

Ian Bamsey replied to Robert Hughes's discussion EXPERIMENTS WITH FOAM SANDWICH CONTRUCTION MATERIALS
"Great work Robert, and really interesting. I look forward to your reports on progress. I think it is to be expected that the failure mode is in the upper, compression, part of the beam. The carbon is particularly strong in tension. I think the…"

"Nice work Robert, I found your experiments really interesting, it certainly got me thinking as to how I can apply some of this in the future, so thank you. One thing I did find quite spectacular was your ability to balance all of those lead weights…"

Robert replied to Robert Hughes's discussion EXPERIMENTS WITH FOAM SANDWICH CONTRUCTION MATERIALS
"Hi Robert, Thanks for publishing this. I am however not a huge fan of carbon fiber unless it is really needed. Sanding and cutting carbon is significantly more hazardous to human health than glass fiber as the fibers cannot be degraded by your body…"

Roger replied to Robert Hughes's discussion EXPERIMENTS WITH FOAM SANDWICH CONTRUCTION MATERIALS
"Hi Robert, Did you also test the glass/epoxy combo to destruction? Even though it deflects more, I wonder if the glass will fail at a higher load than the carbon? Cheers, Roger"

Robert Hughes replied to Robert Hughes's discussion EXPERIMENTS WITH FOAM SANDWICH CONTRUCTION MATERIALS
"Thanks Roger.  The answer to your question is "probably"...  What I've actually used on the floor is a layer of glass with one of carbon / kevlar hybrid cloth on top...  Most likely over-engineered but hey ho! …"

Roger replied to Robert Hughes's discussion EXPERIMENTS WITH FOAM SANDWICH CONTRUCTION MATERIALS
"Hi Robert, Thanks for sharing your experiment - such valuable info. Don't your results also show that that epoxy/glass would also be plenty strong enough to do the job, and also be less vulnerable to dropped anchors et? Roger"

Robert Hughes replied to Frank Higgott's discussion Two stroke or four stroke?? Ahhhh
"Thanks Frank, that's much appreciated. That performance is far better than with my Mariner 5.  Most of the difference must be due to the high thrust prop since I can't get that speed even flat out. My intention is to build the new…"

Robert Hughes replied to Axel's discussion Paying to crew on someone else's boat?
"In addition to potential legal problems in the country where you are operating, my understanding is you can be charged with offences by your flag state, where the boat is registered. For most most ordinary folk that will be their home country.…"
