    Here's another kinda similar rig to Wescraft's* but this one is on bigger boats and has the fore sail as the biggest one...

    * Only a small difference in sail area between fore sail 41 sq ft and main sail 43 sq ft.

    what do you guys think of the triloboat B'Tugly? is it capable of an ocean crossing?

    triloboats will change his whole tune the day he learns freeship
    first learn to understand hulls
    then buy Larsson and Eliasson - Principles of Yacht Design
    the you will understand triloboats better - not good at all

    That depends on the speed of the current.

    Looks like John Riding's 12' Sjo Ag, "Sea Egg".

    If I am not mistaken Sea Egg and John Riding were lost at sea.

    PDWILEY,

    I understand your concerns, cost and safety of the crew. But having been a Pararescueman with the USAF, I can tell you that the safety of the SAR people were never "in grave danger". I'm not trying to minimize their risks, only trying to illustrate that these men and women are highly trained and dedicated people. We always evaluated our risks on every mission, and we always made sure our mission was accomplished. that was WHY we signed up for it to begin with.

    That said, when it comes to cost, Manie was spot on. refugee rescue is a far more daily routine that people are told about. whether it is in OZ or the US or where ever. how do we put a price on saving lives of anyone trying to better their lives anyway? Especially when our government officials waste billions of dollars every year on their junkets, the industrial war complex, etc... the cost of saving lives doesn't even dent our debts...

    And, i'll give you a local example that most likely happens in your area too, here in the states, whenever their is a medical emergency and someone dials 911, they don't roll just an ambulance, they roll out a fire truck, a paramedic truck and usually a pair of police cars too. it's standard practice. Now how much do you think it cost to roll the fire truck alone? here, their cost per hour to operate is something like $5000 an hour, more than a helicopter.

    you want to talk about costs, saving one guy at sea is nothing, trying looking in your own backyard before worrying about that.

    OK, off my soap box....

    I've had a re-look at the aft mast proposal.
    Thought long and hard and this is why not for me.
    It's not that I don't like it - but?

    I'm uncomfortable with the CE moving forward and up - as the sail becomes smaller (furled) on a 10 foot boat.

    Many a small boat sailor has written that you need to keep the mast SHORT on such a small boat - which by default means that a "square" sail will give you more area on a short mast.

    All of this becomes confusing BUT thank goodness that my experiment with the balanced lug will be on the water soon for critical evaluation. Lets hope it works as well as intended and that it could be the good cruising sail. I still draw inspiration on this matter from Matt Layden and Paradox.

    Here is a great video of the simplicity and remarkable efficiency of the sail.

    Manie, great Vid. she was sure heeled on some of those shots!

    I like the lug, I just don't think it will get me to windward as well.

    and I agree that the CE is bit forward of where I would like it.

    Hi Manie

    I suspect the drag of the mast and standing rigging, of a jib only rig, gets proportionally greater as the jib gets smaller. This may well make up for the forward moving CE of the shortened jib.

    The mast and it's rigging act as a mizzen sail that is never furled.

    The problem I have with roller furling schemes is what do you do when something jambs or fails?

    I can guarantee that if that ever happens, it's going to happen in a rising gale.

    I prefer stack sail solutions, such as a Chinese lug, or something closely related. See attachment.

    The boat shown is a pdracer drawn to take on the Everglades Challenge.

    The sail area is divided into three "cells" of almost exactly the same areas.

    The sail is progressively lowered until the last cell collapses.

    It is a compromise between a CL's many battens (which I prefer to call "Boomlets") and the lighter weight of a western rig.

    The split lug form allows the mast to be positioned closer to the skipper.

    I should not be surprised anymore by how audacious humans can be.
    Paging through Phil Bolger's book (Boats with an Open Mind) today, I happened across the Staysail Cat.
    I mean, come on: That is as radical a boat as anyone can conceive.
    I am often guilty of doodling shapes , and they are most often of some flight of fancy about a floating object, long and slender with developable panels.
    Have to admit the old master was way ahead of me. It gives me hope though, makes my more extreme efforts look positively pedestrian in comparison.
    And it has a nice rig on it as well.
