Trimaran Crossbeam Static Load Test

You should also consider the slamming loads, which can be more than the displacement of the whole boat.

 

Interesting question, Gonzo. I guess you have recently read some (one?) studies about salamming. How these forces influence on the transverse beams and how to make these support such a huge force?. How calculate those forces?. Thanks

 

No, it has been a long time since I read anything about it. One of the issues with slamming loads we discussed in a thread a couple of years ago were the lateral forces on the hull which add to the bending of the beams.

 

Well, I thought your information was more recent. Anyway, I'd like you to answer my questions. I have designed some catamarans (passenger and fishing) and had never considered slamming forces (when calculating cross beams). So I would be very interested you to answer my questions.
