We have never made an ultra knife with a big boat, however we had the requirements several times recently. That’s the reason we make this “SYM Grande” for fulfilling that kind of request.

This knife is probably suitable for the ATUMtome unit, if you have that system.
We have both 35-degree and 45-degree with 2mm, 3mm  and 4mm blades.
The big advantage of our Grande compared to the existing Maxi boat is our boat is bigger than the existing one.
The boat size: Length is 1mm longer and width is 2mm wider than Maxi.
If you can put more water into the boat, you will get more benefits for sure.
