Nordic 40 - Mast Deflection ?

I read that the Nordic 40 has a "mast deflection problem" - what exactly does that mean?

Do you have a link to where you read that? It's difficult to define a term that is quoted without context.

Although my knowledge of these yachts isn’t encyclopaedic, I haven't heard any such complaint.

You might ask the designer, Bob Perry:

Read it on a list of boats recommended on Mahina Expedition - Offshore Cruising Instruction - I'll ask John Neal (Mahina captain) and then Bob Perry - I'll post their response
Thanks

That’s a pretty long list of boats, upon which to claim expertise.

What you read was: “...some solvable problems with mast step deflection...”

Nordic Mast Problems

I understood this problem to be related to the mast step. On many Nordic 40's the mast causes the floor to separate from the bulkheads in the area of the mast step. The problem is corrected by inserting a stainless steal plate under the mast to spread the load. I beleive they beef up the tabs in the area between the bulkheads and the floor as well.

I have a picture of the plate installed on a Nordic 44, but I couldn't figure out how to insert it into this post. If you really want to see it, send me a PM.

Hope that helps.

Pat

John Neal of Mahina replied "The problem with Nordic 40's only turns up if the boat is sailed much, and particularly if sailed offshore. The main bulkhead deforms. It is a serious, but fixable problem and I can recommend a surveyor who is very familiar with this problem and how to fix it." This is in line with what Pat says above. If I get the Nordic 40 on my short list I will contact you, Pat, to see the fix.
Thanks

Re: Nordic 40 - Mast Deflection ?

To all those worrywarts who have been concerned with john Neal's description of "mast step deflection" Please note it refers to Nordic 40's,NOT 44's!! Additionally, the builders of Nordic say they have never had to modify or fix this "problem"The photo of the 40 mast step depicts the mast stepped on the cabin sole,unlike the 44's mast which is stepped on the keel. This misperception has caused a lot of heartburn for those with Nordic's for sale.

Re: Nordic 40 - Mast Deflection ?

I own a Nordic 40 - in fact it's hull #1. The mast deflection problem with Nordic 40's is real but the solution is straightforward. My mast was raised and the mast step reinforced. The Nordic 40 is a terrific boat and this problem has an obvious solution. Too bad all of lifes' problems weren't so easy to solve...
