I might even set it up so there are rollers on the front of the Skoota to launch and load.

I just want something light.

Well, it seems like you know what you want but to me it sounds like it's a great tender that wouldn't really work as a lifeboat unless your big boat catches on fire in really calm conditions. No fire = stay on the big boat, fire in rough conditions = swamp the tender immediately and wish you bought the life raft.

I had to swim for shore a couple of weeks ago after my mooring broke loose in a surprise gale...managed to get on the boat and get it away from the rocks and anchored in deeper water, but then I was stuck with the tender on shore, of course. I didn't have to swim very far but even a hundred feet in rough ocean which the sounder marked as 6C (I think that's close to fifty farenheit, maybe a little less) will make an impression on you.

My thought is: if you like it as a tender, and I do, go for it as a tender. But it's not a replacement for a 4-5 person life raft, unless you exclusively motor around extremely protected waters.

That's a calculus everyone needs to do for himself; I spent the last five years commuting forty miles each way over rough water and didn't take a life raft. My boat will float when swamped and I took my chances in regards to fire.

But the odds of having simultaneously run into a fire AND extremely calm water, so calm that panicking people escaping from a flaming boat wouldn't have a problem in a craft with a few inches of freeboard, seem astonishingly remote.

In sum: looks like a fantastic tender; doesn't look like a lifeboat. But then if you need a tender anyway, as you say, there doesn't seem to be any downside to building one.

I think my question kind of got lost in the chatter, but I would still be interested to know if the new foam dinghy will have a sailing option. :)

Last post was 10 weeks ago.

Any action on the TD3 plans?

Last post wanted to know is TD3 will sail. I want to build it!

Does anyone know the float character of 1" thick plascore?

If it is 4#/cu ft, then a 4x8 sheet of 1" thick is 4,608 cubic inches or 2.66 cuft or 10.67# versus water at 62.4#/cuft.

So is it correct to say 62.4x2.66 - 10.67 or say 155 pounds of glass and resin can be added to neutral buoyancy?

Or, more specifically; can we make some glass assumptions..

Assume 17 oz biax both sides and a resin rich layup of 100% plus the veil wetout.

So, the glass is 60.5 ounces per side and the epoxy is the same plus say 24 ounces for the thirsty veil. Or 300 ounces, or 18.75 pounds for a final weight of say 30 pounds. So, it'd float I'd say, but pretty heavy.

Wow! Too heavy.

The TD3 will need to be build in foam.

The plans are 100% ready but I want to show them at the same time that I publish the Foam Sandwich shop manual. The manual is not ready. Eahc time I think it's complete, I edit a part, add something.
I"ll keep working on it.

BTW, I don't remember saying that it would sail. It is designed for rowing or outboard propulsion.

Thanks, that is what I wanted to know. Better to wait on releasing the manual until you are happy with it.

I'd like to start work on the dinghy in 90 days.

Possible?

Who is proofreading for you?

I am a decent proofreader.

The plans are ready but not the notes.

Our drafter, Crystal, writes better than I do and volunteered to proof read but I may send you a copy too.

I got these plans, but can't do anything with them until the hulls are painted for the Skoota.

Gonna be a great boat.
