Hi captains!
I recently joined this forum, and as a Linssen employee, I wanted to react on some of the comments and clearify some things that I've read here. Some members might have seen my posts in another thread already, but I've seen some new questions here.
The headroom on a 35 foot Linssen can be too low for some captains whom play basketball too.
But it has to do with draft: a 35 has a draft of 1 meter (3.3 feet). If you size up to 40 foot or bigger, the draft is 1.2 meters (3,9 feet) and this difference of .6 feet will be noticed in headroom immediatly; even your average basketball player can stand up straight in them!
To reply on the filler-issue: the trick is using tension free sheets of metal and weld smoothly and use as little as filler as required. Filler is the weakest link in the construction. The welding seams might need some filler to make them smoother and of course, tubes that are welded on need to be fillered above, so water will flow off, instead of staying in between. A 40 foot hull needs less then 100 kilograms of filler; the metal sheets have hardly any filler on them.
By the way, insulation for our bigger models (>40 foot) is done with rockwool, not EPS.
A steel boat can handle salt water just fine, no better or worse then plastic. Especailly with nowadays coating systems, you don't need to worry too much about it. Yes, it can rust when the paintwork is damaged, but the nice thing about steel is, it's easy to repair: sand the damage and apply new coating and you are protected again. And in reply to Mr. Blu; I suspect you lookad at an older model since a common issue for older steel boats, is the anchor chain locker: if you anchor a lot, the (wet) chain will damage the coating inside the locker. If you don't pay attention to that, it will eventually start to rust, especially on salt water. And then, parts of the bow might need to be replaced. However; we solved that issue in our current generation of boats by installing a thick plastic and self-drained bin inside the chain locker, so the chain can no longer damage the steel.
But if any of you are ever in the Netherland and want to come have a look, just contact me for appointment and I will give you a factory tour, so you can see all production stages yourself. My contact details can be found on our website. And for further questions, you can contact me too, or simply post a reply.
Look forward to hear from you!
Cheers, Rennie
