Don Silsbe Posted June 19, 2021 Report Share Posted June 19, 2021 In the past, we’ve discussed improving the floatation in Graham’s nesting boats. To complicate matters, I like sailing on my backside. This summer, I’m doing an experiment. I’m adding some removable floatation tanks to my Two Paw 8. They’re made of junk plywood, and might last one season of sailing. But it will allow me to evaluate their effectiveness. Two Bits won’t get wet for a few more weeks. But this is where I am today. This is where they’ll go. Held in place with two screws each. And they can come out, if they don’t work out. Now, they need fillets and lids. Next, some sanding and paint.

Don Silsbe Posted June 28, 2021 Author Report Share Posted June 28, 2021 FLOATATION UPDATE I’ve made my two forward floatation tanks. The paint is drying. We head North tomorrow afternoon. I’ll pack it all, and play with it in a few weeks. We’ll be at a lakeside campground then, and I can play with it. 1 Quote Link to comment Share on other sites More sharing options...
dwg2116 Posted July 11, 2021 Report Share Posted July 11, 2021 That top inside corner looks sharp and uncomfortable. Is there still time to give it a 2" radius before you glue the lid on? Or maybe just a 45 degree cut? Quote Link to comment Share on other sites More sharing options...
Don Silsbe Posted July 12, 2021 Author Report Share Posted July 12, 2021 The top inside corners are flush with the forward seat, and not a problem. The after inboard corners do protrude. It’ll be interesting to see how they work. This is a prototype, anyway, made with junk plywood. If they work, I’ll commit my 4mm to the replacements. If modifications must be made, I’ll do it then. But thanks for “pointing” those points out to me. Food for thought. Quote Link to comment Share on other sites More sharing options...
Starboard Posted July 13, 2021 Report Share Posted July 13, 2021 I like the idea of removable flotation- I toyed with that idea on the my Spindrift 10n. Ultimately I decided to build it in where the previous removable seats had been since it doesn't affect the nesting ability and only adds a small amount to the overall weight.

Don Silsbe Posted July 22, 2021 Author Report Share Posted July 22, 2021 Let’s talk TRASH! I mean the T.R.A.S.H., to use PiedTyper’s acronym. Today, I finally got to do some in-water testing. The results were interesting. First, I capsized her without T.R.A.S.H. She took on a lot of water. But the water level was about 2” below the top of the d/b trunk. That way, you can actually make progress with bailing. But it was a lot of water! Then, I installed the floatation. The first thing I noticed after capsizing her is that she immediately wanted to turn turtle! Good to know. I expected her to float stern-low, but that wasn’t the case. The weight of the sailing rig must create a downward pull on the hull. Whatever the reason, there was very little water in the forward compartment, and much less aft. I like it! I could tinker with adding some floatation in the after compartment, but I don’t think I will. My big butt takes up a lot of space just aft of the split, and my knees like poking aft occasionally. We’ll see about some temporary tanks… maybe. I left them in, when I went sailing afterward. Quote Link to comment Share on other sites More sharing options...
PadrePoint Posted July 23, 2021 Report Share Posted July 23, 2021 Sounds like a fun, useful day. 1 Quote Link to comment Share on other sites More sharing options...
Hirilonde Posted July 23, 2021 Report Share Posted July 23, 2021 That is a big difference. And even as a tender, the space lost is tolerable. Quote Link to comment Share on other sites More sharing options...
Don Silsbe Posted July 23, 2021 Author Report Share Posted July 23, 2021 @Hirilonde— I hadn’t thought about that, because that’s not how I use her. But you are right, although as a tender, it would be less comfortable to row from the forward position. Quote Link to comment Share on other sites More sharing options...
Don Silsbe Posted July 26, 2021 Author Report Share Posted July 26, 2021 I posted these results on the Duckworks FB page. Michael Storer suggests that too much floatation will turn a boat turtle more quickly. I’m thinking about reducing the volume on one side, taking a tank down in height by a couple of inches. I’m wondering if the short mast will turn her turtle regardless. Thoughts? Quote Link to comment Share on other sites More sharing options...
