Hello. I'm seeing and hearing conflicting statements about the hull composition of 695 boats. On the one hand, sources state that the 695 has a laminated sandwich composition consisting of fiberglass, a balsa wood core, and polyester. On the other hand, other sources state that the 695 hull is composed of fiberglass and GRP.
Without necessarily going into the pros & cons of either, which is correct?
Thanks!

I'll answer my own question, then:
The 695 hull, below and above the waterline, is "laminated sandwich glass, balsa wood core, and GRP". Fabrication relies on injection. The same is true for all boats in the X95 class. Info is from Jeanneau in France.

And yet....
Just received second message from another part of the Jeanneau conglomerate stating that the 695 / X95 hulls are glass sandwich, GRP and Kevlar -- *no* balsa wood. So the left does not know the right and vice versa....
Has anyone actually taken a through coring sample on any of these boats?

There is no balsa in it. |

Appreciate the info. Not sure why there's confusion on Jeanneau's part, but perhaps not too surprised given the nature of large organizations.

I wonder whether these different compositions might apply to the hull (no balsa core) and the deck (with balsa). It's common to use different fabrication for these components. A core sample is definitely the best way to know for sure.

A core sample is definitely the best way to know for sure. Both Jeanneau sources sent me a jpeg of a portion of a page entitled "technical specifications", which included the supposed composition of deck and hull. In both cases the deck composition was listed as laminated glass sandwich, GRP, and sinter & foam, with a wet-laid fiber process. In one case the hull composition was described as laminated glass sandwich, GRP, and balsa wood. In the other case, the hull composition was characterized as laminated glass sandwich, Kevlar and GRP. Both processes depended on injection. I agree that, at this point, a core sample is probably the only way to know for certain. That's not an option, however, since I'm doing my due diligence before buying the boat. (The other boat in the mix is a Sailfish 220 WAC; the wife likes the 695 much better, however.) But I do appreciate the input. |

But I do appreciate the input. My look at the core comes from drilling a 3” hole in port side for exhaust of a head vent fan. IMO, every boat should have an exhaust fan in the head as humidity is a big problem when showering and at other times, odors can be an issue. Drilling a 3” hole isn’t for the faint of heart, though either. |

An update. I bought the 695. The technical specs in the owners manual lists a cored hull and transom with balsa and a fiberglass deck and stringers with sintered foam. However, in relocating the transducer and installing trim tabs, no balsa was found in any of the transom through holes, factory-drilled or new, top of the transom to the bottom, one side to the other.
In addition, the outboard fitting of the grey water discharge had to be replaced, located low on starboard hull. No balsa was evident there, either.
Possibilities:
1. No balsa. The owners manual has not been updated; neither has Jeanneau customer service.
2. No balsa in the transom. Limited balsa used in the hull, at some point above the water line. Owners manual and customer service unclear.
3. Factory chimera. This boat doesn't have balsa. Other boats do... or don't.
#2 seems the best bet.

Jcam,
That’s interesting. My first jeanneau was a 695. I didn’t have to cut any holes in it. I guess the only way to find out what these boats are made of is to cut them into little pieces :,(
