Re: Sailboat without a mast

A dismasted sailboat (keelboat) will be adversely affected. This is a well-established fact as discovered and confirmed by some of the leading minds in sailing while investigating the Fastnet '79 disaster. Think of a metronome. Now remove the counterweight and cut the long stem off. With only the lower pendulum, that thing wiggles back and forth in maniacal fashion. Basically the same principle. The mast and rigging weigh less than the ballast, but exert a leveraging force to slow the motion against the force of the ballast. The effect will vary with each design, but the change is a fact.

I have been thinking about this same thing for a year. I've owned every type of vessel and I can say without exception a sailboat has more room in it than a power boat. My goal is to buy one and have the keel removed so that I have a smooth hull bottom. Without sails there will be no need for it or any ballast since loading up the boat with basic supplies will be sufficient. I'm not heading out for a long cruise or week long trip. Just great time on the water for a week at a time on Texas lakes. It needs to be able to be towed which is another reason I have decided to remove the keel. Looked at MacGreggors and they would be great but too expensive. I'm hoping to get one from a marina that has had to confiscate it due to non-paid slip fees and have them strip it of rigging and cut the keel off. I'll then trailer it to a fiberglass shop to have the bottom repaired from the keel removal and a new bottom job. Then it's off to my covered shop to start re-doing it from stem to stern. Keeping it simple will make it more user friendly. Motor will be a 40 hp outboard with steering cables and throttle/trans. I'm going to use a 'cajun' style stick steering so it's not in the way. That's my current thought.
What else can anyone offer me as I get closer to doing this?

Maybe in big water, but on a Texas lake on a generally calm day, tooling around the place and fishing. It would not produce any ill effects IMHO.

I think a powerboat makes a better powerboat.
It's doable, sure, but you're making compromises in comfort to gain nothing. Plus you'll have to answer a million dumb questions.
I have been in many MacGregors and under power or anchored off (without sails even being on the boat, mast removed as well) the boat operates just like a powerboat. I think some of the comments are made by purists of sailing which is okay but todays MacGregors can and do work perfectly under sail and pulling a skier with out board motor. So I kinda gotta take a lot of the discontent with a cup of salt.

Dude, buy the proper tool for your task instead of trying to (poorly) adapt the wrong tool to your intended task. Sailboats with their masts, often motor uncomfortably. I can't imagine doing a long trip without the mast.
Lots of info here is foolish. You folks ever ride on a MacGregor, both under sail and under power pulling a skier? I have. It operates perfectly under either set up.

Re: Sailboat without a mast

Might be easier to get a centerboard boat and a pair of wire cutters than remove a keel. Put boat in 6 feet of water, cut centerboard cable, remove pivot bolt and presto, ya got an unballasted sailboat hull.

Great advice if you find a sailboat that has such and meets whatever criteria you may have laid out. Swing keel's are easy to remove.

Re: Sailboat without a mast

There are also purpose built small 'trawlers' that were designed for this sort of thing that would do the job as well if not better, without having to 'butcher' anything.

North Sea 26, Davidson 'Chugger', Albin 25 to name a few. These will have similar accommodations, likely a slightly bigger powerplant and would be working as designed, not a modified misfit....

Re: Sailboat without a mast

This seems like an appropriate thread to post my latest "find".

Easy now, put down the chainsaw. I can't think of a simpler way to to get a power boat. you could do it the hard way and buy a powerboat and add the cajun steering then you could use it to catch Gators.
most of us here on SN are trying the best we can to keep the mast up.
