howdy,i would really appreciate some help on this.i live in mexico,ive found a 35 foot abandoned barracuta motor boat. all hardware has been stripped.i need to move it about 40 or so kilom.we are poor ,the truth real poor,we are planning to do this on around 50 bucks,we found a sail .kinda ripped up but we got 2 sails out of it,found a sewing machine,3 days later it was sewing.fixed the holes and put the hotes on two sides to put the ropes in.we have a picture and we try and copy that.any way the question is do we need a keel?and is this keel going to keep us from going sideways.?only material we have is 1 piece of 3/4 in.plywood.my other concern is the water the first 2 k.isthree and a half to 5 ft. so we need this keel to slide up and down in case it hits bottom on the way out into the ocean.we have one half gallon of fiberglass resin hardnerone teaspoon.big piece of fiberglass.the kind with pieces hanging out of it,like hair.i tell you this as i asume a hole will have to be cut into the bottom of this boat.we were planning to extend the dides of the hole higher than the water line so water wont come in.we werent sure this would work.plan b i thought on cutting the plywood in half and screwing one piece on each side of the boat extending into the watera couple ft or so whitch idea is best ?our recources are limited.we aresailing in a couple days.be kind with your answeres we are real people who have had little opertunities down here,but our love for the ocean is never ending.theres a large number of people whom know nothing of the wind.but we know its there.prices of gasoline has put the poorer fishing persons out to rowing to work ,my idia was to show them the wind.i know very little of the wind .this all came about the otherday as we were rowing to the work .a couple hours into the early morning.a gringo sailboat came by us as if we were standing still.my rowing buddy and i stopped rowing and just couldnt believe it when my friend said pinchy gringos have good motors coulnt even hear it.i told him that boat doesnt have a motor ,he says bullshit all boats use motors,i said no they dont,and i will prove it to you.and i did.one day i will tell you about the sailboat we made in one night and sailed in the morning.out of one dide of my garage and one roll of dibiton roofing.its still afloat.thankskevin
