Characteristics - seaworthiness


22 May 2019 | Last update: 23 Dec 2020

As far as seaworthiness goes, Gemini’s construction is all about strength. Really, she is overbuilt, to give confidence when dealing with rough weather. The structural, oak ribs are set just 6 inches apart, and every second rib is double-thickness timber. As I’ve already mentioned, the canoe stern also gives a very strong structure.

She has twin forestays, so if one breaks, the other is backup. And the narrow hull and heavy lead keel mean she is exceptionally resistant to capsizing, and if it should ever happen, she would flip back up within seconds. Many modern boats, with their broad hulls and ballast keels of just a few hundred kilograms, are remarkably stable when upside down.

Most of Gemini is actually under the water. That 5 ½ tonne keel pulls her down. It means that down below, there is plenty of headroom – more than 6 feet. Nevertheless, she doesn’t have much freeboard – the expanse of hull above the water. This is a good thing. Freeboard acts like a sail, except you have no control over it. The wind force against the side of the boat can be a significant factor, pushing the boat down to leeward when you really want to stay up to windward. Compare that with modern boats. Their light weight and flat bottom means that in order to provide a comfortable amount of headroom inside, they have to build hulls with lots of freeboard. The combination of large freeboard and light weight makes for a boat that falls down to leeward rather easily.

Fantastic experience

My wife and I recently had the pleasure of sailing with Dave on the Gemini. It was an unforgettable experience. Dave is a pleasure personally and a very professional skipper. The boat is beautiful as well. He stopped twice so we could have a swim. He provides water but if you want anything else to drink or eat you gotta bring it. If you are thinking about sailing in Barcelona.. don't hesitate. Book with Dave and you wont be disappointed!

Great afternoon out!!

Having read all the great reviews, we booked this (family of three including 14 year old daughter)... we were not disappointed and had a great afternoon gently sailing around the bay off Barcelona Marina. Dave was a friendly host which made the trip even better... you won't regret booking this.

Great boat and great skipper.

Great sail boat with an interesting history. Dave is a well-informed Scotsman who has been in Barcelona for almost a decade. He has a great website and I booked a bit in advance and he handled all my questions. We had a rare choppy sea (and some haze) so we missed the swim but the whole afternoon was relaxing.
