Thames 4 Blood... it is an illusion, that "heavy boats" are safely. The Mediterranean
is not a "harmless" big pont sea area. If you'd sail street of Sicily
it can be very rough weather with big and choppy waves. In other words: if you can sail with a 40 footer Jeanneau there, it same could take the pacific safely.
If your theory would be correct, we'd not loose every week two ships worldwide ( see annually report by Alliance: AGCS Safety and Shipping Review 2014)
The right formula is: More lighter a boat, more better = safe". So the basic concept
. Otherwise Polynesians (with multihulls/proas) or Vikings wouldnt have crossed oceans. What counts is length of a boat and the uplift a hull gives in the segment of bow and stern !
I rember very well, I visited a workshop of Burghard Pieske
(born 1944), a solo circumnavigation
salor, and very radically in his projects. But not mad, always keeps his activities on high seas on the safe side. - He sailed catamarans, he followed the route
of Vikings with a replica of a Viking boat...
...and the Pacific on the route
Blyte and his Bounty cross the Pacific...
Burkgard explained it very simple why light-weighted boats have it more easy in "bad weather" and "heavy seas". They pop up like a bottle or light-weighted piece of cork. Jumping easily on the waves... and not being drowned/overwashed like a heavy piece of wood sucked full of water
. Therefor they are safer compared to heavy keel boats.
While a heavy long keel boat is laying deep in the water, and steadily fighting against the elements which can bear the risks to slow down by speed and stuck... and become a victim / play ball of the elements.
If you have the money
and budget, think about a "used multihull" as you search for "space". Cruising Catamarans nowadays are very, very safe boats.... enough out there in the range of 200-250 Thousand... These boats will give you all what you want: safetyness (inclusive speed as a safety
parameter), space and comfortable accomocation even in bad weater (see the 1st video). - Cats will give you what you want. - A 45-50 foot multihull
has much more benefits than a monohull
of that size. Only limitation: you shall not pack it overweighted, so the sterns suck deep in the water to loose the "leight weighted cork" effect.
Enjoy the ride on a 50 ft. cat in the Pacific...
Very relaxed sailing under Wind Vane
on a 43 ft. cat in the Pacific...
A long keel boat I only would like to take in ice areas to have a very robust hull.
