Characteristics - seaworthiness


22 May 2019 | Last update: 28 Jun 2019

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.

Fabulous sunset sail

We had a brilliant time on board Gemini with Dave. Very relaxed and welcoming. It's a beautiful boat and Dave could not to be more helpful or accommodating - and the sunset over the mountains was stunning. You get to see a unique view of the Barcelona skyline and coast and you can either relax with the sails blowing as he skippers or if you want you can help with the piloting of the boat. And it's great value too!!

Great sail!

This sail around Barcelona was the highlight of our trip! Captain Dave is fantastic; he made us feel welcome and at home on his wonderful boat. We loved that the sail was just our family and was so reasonably priced. We highly recommend this trip and will absolutely do it again when we return to Spain!

Charming Boat with a friendly skipper

I thoroughly a 3 hour cruise with Captain Dave on board Gemini. The boat oozes charm and is really interesting in its setup. As someone who only recently started sailing, i had an amazing time chatting with Captain Dave. Even thiugh the wind was very light, i had a great time. Highly recommended

Romantic sunset sail.

I booked a sunset sail for just me and my girlfriend. It was everything I had hoped for. We took a dip in the Mediterranean and watched a beautiful sunset over the city and mountain to the west. Captain Dave was knowledgeable and put us at ease right away. He allowed us just to sit back and enjoy the trip.

Excellent change of pace from busy Barca

Fantastic day out and got my first hands - on experience of sailing which was exhilarating. David was great company. Bring food, water and warm, wind-proof clothes - it's much cooler out on the water. This would be an amazingly refreshing experience in summer. Thank you David!
