Want more speed and performance!!!!!!

[MarioCoccon]

Hi, Iam looking for ad more upwind performance and speed generally to my newport 27. The boat have a finn keel 5 draft and a spade rudder 4 draft with a 37 feet mast. I'am thinking in put a long boom to ad more main area but afraid that this could cause wheather helm. What if I increase the Genoa too?? or maybe leave the main original and put a 180% Genoa. I saw a lot of boat J generally with gigs mains and lower and smaller genoas or gibs. Please if someone have any suggestion will be appreciatte. What is more apropiate a tall sails but short in the foot or long foot and short of tall maybe like this the boat heels less wright??. The last owner cross the world in him and he cut the mast from 37 to 34 put a 180% Genoa and a little main he toll me the boat was balance perfect, but I have a 37 mast and I want to put that boat flying the more possible. Thanks

Mario;
Changing the rig may present some problems that you may not want. Your decision to make changes depends on what you intend to do with the boat. If you are going to do some extended cruising, then leave the boat as it is. The previous owner was probably correct to reduce mast height. That is because he was going to do many days at sea. Comfort and a little added safety are more valuable than a few tenths of a knot.

If you intend to race the boat in reasonably sheltered waters, that is a different situation. In general a taller luff is more efficient going to windward. (Tall sail short boom) . Yes, the boat will be more likely to heel with a tall rig. Most boats have an optimum heel angle. If the tall rig overwhelms the boat and causes it to heel more than it should, you'll go slower, not faster. More generalities; A short luff and long boom is likely to be more powerful off the wind than the tall narrow rig.

If racing is your purpose, then the ability to go fast to windward is well worth the effort. Of course there is the matter of expense that must be accounted for. If cruising is your aim, then leave the boat as it is, save a lot of money, and sail more comfortably.

Hi and thanks for the reply, in investment I was lucky because I already have the tall mast and a additional long boom and a roller furling the only thing needed are the sails, I know they are very expensive but I can try with old ones. You say more windward speed tall sails short boom, that count to the Genoa too? maybe put a 130 not a 160%?? and what about the reach and downwind will be affected in your opinion?. thanks a lot for your time. I think if not work I can cut everything doen a little bit I have staloks in the rigging. please let me know when you can that info. Thanks Mario

Anyone else, please all opinions are gradefull, I want choices because now is the moment to do any chance I have the boat in restoration. Thanks

Want more opinions please anyone else. Thanks

For upwind performance a high aspect ratio would be best.
I think a taller mast and keeping the shorter boom would be a good choice. Full length batterns and a tall 110 % genoa too.

Mario,

Do yourself a favor and spend a few bucks with a local Naval Architect or competent boat designer in Puerto Rico. Have them look the boat over, make some preliminary measurements and let them present the case for a bigger rig for your boat.

I know of a guy in St. Augustine, Florida who would be ideal for this particular problem:

Eric W. Sponberg
Naval Architect, PE (CT)
St. Augustine, FL
(904) 460-9494

Without the proper experience, you are only asking for a room full of headaches as you try to sort-out all the possible outcomes and reasons why they came about.

Hi: And thanks for both to reply me, an owner for a Newport 27s the one came tall rig like my before tell me his mast is 36 and the boom 11 and the boat with a 150% heel 30 degrees in 15 knots of wind but more than that he need to short sails. Sounds fair but I need to asking if he have weather helm with that combi. Thanks

Hi: Another ?? I have a little race next weekend of a family sailing club I create. The all passage is reach and down reach. My columbia 39 sail like a maniac in this position but I need to be sure to win my friend boat. I have a big main and a 160% Gen0a, if I put a little gib like a cutter its possible to increase my speed or can damage my genoa shape??. I already have everything set to put a sail like a cutter. Please cutter ones let me know. Thanks

My boat is a Cole 26, also a cruiser/racer. The old quarter ton class so I'm told.
Anyway, I cannot give you mast/boom dimensions but my#1 Genoa is 150%
My #2 120% and so on down.
With the #1 up I can sail quickly in a very light breeze but it must be a light breeze as it will soon overpower the boat. The #2 is ideal as it seems to perfectly balance with the main.
Without exact figures I realise this is only very general data, but my point is that I can sail very comfortably with my #2 and in the end the boat is really not a lot slower.
