Kelt 8m
Deep draft

The Kelt 8m is cruising monohull designed collaboratively by Kelt and Gilles Ollier after a dialogue about the expectations of the Kelt’s owners. She is a relatively wide for the time. The Kelt 8m is fast in light winds due to her small wetted surface and very comfortable upwind even in the breeze. Downwind she is penalized by the slope of her bottom.

Inside the layout is rather classic, the saloon enjoys the large width and only the folding table betrays the real size of the boat. To gain even a little more space the chart table slides above the navigator berth. The front part host a toilet behind the fore double cabin.

Initially available in keelboat deep draft and shoal draft, the Kelt 8m was proposed in centerboard version in 1981; only the deeper version cannot dry-dock.
