My mantra is: You don't know how to do something until you've done it at least once. I'm really enjoying the build series. You and Matt do a good job of balancing the hows with the whys without getting tedious.

Just remember that the next time you build another catamaran…lol. Live and learn, a few extra beers will help, can’t wait to see her sail. Thanks for sharing.

I would say it’s a stronger learning event either way there is allot more to go. Wishing you the best on a big project.

On refits. I see everyone using orbital sanders to do heavy grinding. I think that a belt sander would be a lot faster and you can put a vacuum attachment on a belt sander

less than 3 kg (75 oz) won't hurt your performance , don't loose sleep over it

Couldn't you fill the resin with microballons? Save a lot of weight and create lots of volume, not sure with vinyl ester... Never worked with that only epoxy.

You keep mentioning trouble keeping your mixed resin from flashing off too quickly in the heat. Take a little tip from me as someone who has done lots fibreglass and 2-part paint in the heat. Keep your resin drums in a bath of water, adding ice or refrigeration if you can, keeping the drums at or just below the working temp of the resin. Don’t get below the storage temp. If the resin drum is metal, varnish it first so it won’t rust. The more water the better to keep as stable temp as possible. Use a kitchen thermometer strapped permanently inside to monitor the water temp- you don’t want to go below the working temp range. Same for catalysts. When mixing, mix the resins in tubs dipped in a shallow plastic kitchen sink (like the ones you used in the kitchen or cleaning around the house) filled with water, adding ice if necessary to keep the resin at the lowest working temperature. Use a metal plate or bar to stop the tub from floating if you don’t hold it in the water. When at your work area, the resin will rise in temp quickly due to ambient temp and chemical reaction, but your working time will be vastly lengthened, giving the resin time to flow into crevices better and flash off at a lower temp, hopefully in its working temp range, which is good. Hard to predict extra time you’ll get, but it WILL be longer. Same with 2-part paints and gel coats. Have fun!

Lol, oh well. If you don't screw up now and then, your not doing anything....

You never answered my initial post about what the instructions tell you'se to do.

We ended up mixing about 75 oz of thickened resin while preparing to glass our bridge deck seam .... only to realize later we could have filled the area with spare foam. I wonder how much vinyl ester that would have saved us? Oh well, too late now. This is how we learn.
