<p>This sounds authoritative and confident. But it misses several points. You seem to be talking hypothetically. Larry and I and others (Jason Cajune) have been building with honeycomb core for years now. I hope to experiment with CoreCell and/or DiviniCell foam soon. But I do know I prefer honeycomb core to plywood (for the bottom panel anyway). So. Several points:</p>

<p>Who are we talking about? The boat buying public at large or the do-it-yourself boat builder? Boat builders tend to be careful rowers. I've been making drift boats since 1979. I use my boats hard. But don't hit very hard. Not often. I pay attention. I read the water. I row with skill. When I do smack a rock I fix it.</p>
<p>Yes, delamination is a problem with honeycomb core. But it's a problem with plywood too. Honeycomb core is patchable. I do it all the time. </p>
<p></p>
<p>Honeycomb core does NOT necessarily depend on a thick heavy fiberglass outside bottom. 4 or 5 layers of 6 to 10oz glass makes a stout bottom that is STILL lighter than plywood (if that plywood is glassed, perhaps with a few less layers).</p>
<p></p>
<p>A bottom like that will get dinged. If you are a consumer you're stuck. You have to go back to the boat dealer and beg for mercy. If you are a boat builder you just fix it. Plywood skinned in glass is far more trouble in the long run. </p> In part of my past life I wor…tag:woodenboatpeople.org,2012-10-06:1312281:Comment:881602012-10-06T19:38:57.848ZBob burdahttp://woodenboatpeople.org/profile/Bobburda
In part of my past life I worked for a structural core manufacture. People tend to incorporate new materials into traditional structures based solely on price. You have got to look at the life cycle and the intended use/environment of the boat hull in this case and you will always be able to justify buying better materials to keep the best quality and toughness possible. Even maintaining an all wood boat. Cold molding is a very good example of that. Basically layering veneers to produce your…

<p>Bob, your responses was exactly the sort of thing I was looking for when I started this post. I found your technical insight quite interesting and hope you continue to offer your perspective. This forum is about building wooden boats but when new and advanced products start becoming integrated with wood it's important everyone gets insight from those who have experience with them.</p>

<p>Bob you voice some good points about cores. I won't ask for more here as this is a wood forum. It would be great for you to check the forum at montana-riverboats.com where many of us are looking for wood alternatives. </p>

<p>Every time I buy plywood it seems worse then the previous year and costs more. I wonder what it will be like 25 years from now?</p>

I would not use any plastic honeycomb in a boat bottom or sides. The nature of how honeycomb reacts to impacts requires bonding to thick skins,(heavy) so what is the point. HC will crush in a localized impact with properly sized glass skins if weight is what your trying to save.In the world of sandwich construction honeycomb has a greatly reduced bonding surface area, little sound and temp insulation value and water ingress from damage and condensation. It is low $. If your going to have…
I would not use any plastic honeycomb in a boat bottom or sides. The nature of how honeycomb reacts to impacts requires bonding to thick skins,(heavy) so what is the point. HC will crush in a localized impact with properly sized glass skins if weight is what your trying to save.In the world of sandwich construction honeycomb has a greatly reduced bonding surface area, little sound and temp insulation value and water ingress from damage and condensation. It is low $. If your going to have sandwich panels in your hull I would use a 6lb density PVC or SAN foam core. There are no plastic cores that are approved for primary structural applications in the world of ABS and DNV classifications. Great for interior panels. Last comment for today is processing. To minimize secondary bonding issues the core should be vacuum bagged or infused to the skins. You inherently use more resin and adhesive to bond HC vs foam core. Goes against the rules of proper sandwich construction. Duane,

<p>Duane,</p>
<p></p>
<p>I have built 2 all plascore hulls. One an open fishing drifter and the other is a decked whitewater boat. I have build history on web sites for both. I have used plascore on the bottom of a third. I have another friend who just completed his all plascore boat this past summer. We have 3 plascore boats going down the Grand Canyon in about 3 weeks.</p>

<p>Hi Duane,</p>
<p>i think the real use of these composites in drift boats is theres no concern for rot,also the ability to absorb impact.Honeycomb is also the cheapest of cores so i think this is why its the most popular.Is it the best?i cant answer that,but there are alot of boats using this as a bottom.</p>

<address>one concern is delamination of the glass,this is mostly do to builder error( i think).theres lots to learn about these composites in drift boat building,i think its the way to go if you abuse your boat.</address>
