Well--my trimaran is just over forty feet and has berths in the wing decks which free up a lot of space in the admittedly narrow hull when compared to a forty foot mono--except perhaps some of the designs built for speed rather than cruising comfort.
The trimaran stops a lot of wind
when at anchor
compared to a mono--and if I have a criticism of this one, it is the slender entry of the hulls which tend to limit the weight which needs to be carried forward--such as a decent sized anchor
and chain and a windlass
to retrieve it all.
The strongest wind
I have encountered with a lee shore was forty five knots with gusts to sixty, and by taking them on the quarter was able to forge my way out to deeper water well away from the reefs
. I will not say I was afraid--just concerned to the max--green water over the port ama dorade box forward ventillator is not something I wish to see a lot of the time--fortunately the thing worked well and we only shipped a little water.
The good thing about a trimaran--and a cat too for that matter--is the stable platform it has when at anchor. The Loadstar does have full head
room in the saloon
and sitting headroom
if the front and aft cabins. Heavily loaded with water and fuel
she does about half windspeed, but the best she has done with a cruising load of stores, water and fuel
is about ten knots--which many monohulls would also do in the sixteen to twenty knots of breeze it likes best.
If I were to change anything, I would prefer a more complex bow which would give a fine entry for the normal seas one encounters, but with a little more flare for more bouyancy. Pitchpoling can be a real problem with trimarans. I have considered fitting inflatable
bouyancy around deck
shelf outer beltings, just to lift
the bows more quickly should they ever dig in. Any thoughts on this welcome.
My tri is underpowered by most standards. It rigged as a cutter
but I hardly ever use other than the main and genoa
, which gets her up to eight knots or so.
Trimarans are superb coastal cruisers--that is a fact. For offshore
work in severe conditions--I am less enthusiastic. I have been in rough seas--but not for days on end. The need to watch constantly for extra big waves would be very tiresome indeed. A trimaran or a cat sheds little wind compared to a monohull which can roll away from the wind and present higher sides of the hull to weather--trimarans get wet in such conditions and reefing early saves broken gear
Then there have been cases when whales have attacked trimarans--
The amas on the Loadstar could each easily be made into 2 single
cabins. One might retain some of the storeage by putting it under the bunks, where the bunk is the lid of a stores bin. The main thing is not to overload the amas--and since they are only likely to be occupied when at anchor or beached--they are certainly useable. In rough weather
the hatches need to stay closed. I may explore this option later.
