All very good information. RIP Jeff you were a good man…

I’m so bummed I missed my opportunity to connect with Jeff. Rest in peace. ❤❤

RIP. Love the description of the dead head log. Go right through a steel hull even.

Thank Jeff for your " Spira Boats "

Once again, Jeff answered one of my many concerns again in another informative video. Thanks Jeff

As always Jeff great video. and thank you for explaining the logic behind floatation. I've considered building my own boat for a very long time. the down side for me is my boat I want to build is 15'X60' wide body narrows boat. finding a boat yard to rent the space to build from scratch as become quite the issue for me. everyone I've talked to says the same thing. If its already built and I need a haul out they have space. other wise they don't have time or space. and doing a backyard build for a boat that size isn't really a logical move in the right direction either.

One way to provide flotation while allowing the boat to dry out would be to attach the bench seats to the ribs in the floor and sides rather than attaching directly to the sides and bottom. My plan is to make a built in cooler in the middle of the addy section bench with two compartments on either side filled with two part expanding polyurethane foam. This should be plenty for up to a 20hp engine. Then again at the middle seat to compensate for the battery and again in the bow to compensate for the anchor and trolling motor. The area below and to the sides will have air flow so even with a bottom on the bench the hull will dry out. At most the bench might eventually rot because I plan to cover the top and sides with fiberglass but it can be replaced fairly easily if rotting becomes an issue. Sure wish I could run this by Jeff. RIP 🙏

Thanks Jeff your videos are very nice at really late hours

My boat mechanic recently gave me a big old spiel about foam taking on water and weighing tons. He said you’re better off using old 2 liter bottles (probably encased in boat foam) than just foam alone. Makes a ton of sense.

Rest in peace, it looks like you passed away sometime in late 2021 early 2022 & someone has pirated your website since then. So sad, some people. Mr. Spiral you are/were an inspection to me

Jeff, I would like to request a video on your Deadrise boats....Tangier and Pokomoke.

Thanks for all these videos, they are really helping me out in making a decision. I'm 28 and have always canoed and kayak fished all my life, BWCA and some white water kayaking too. I've been wanting a little jon boat for the lakes out here in MO, I have a old Sea King/Clinton 7hp 2 stroke I inherited but know I want a 25hp for hitting the mighty mo. I don't feel comfortable with budgeting a new 25 with as much boat as I can get which would be a 1542 jon. I did a little research into building one which led me here and I feel much more comfortable in the prospect of building the 16' Garvey Dory and being able the get the boat I want with the engine to push it as well, without having to compromise. Hopefully I can make a winter project out of it soon. Kind regards, Chris St. Clair

Getting pooped isn't fun, lol. My favorite is your drop ramp dory, the mini Higgins, only because I always wanted to take a motorcycle. Thanks!

Thanks Jeff. Very very informative!

Thanks!! Great information!!!!

You have answered all of my questions about flotation so my next query will be the tag that tells maximum horsepower and how much weight or people the boat can carry and is this tag even a requirement on a home built boat. So far I have learned just enough about it to really confuse me. Thanks Jeff I always enjoy your videos...

Great talk and video Thx :)

Thank you Jeff!!! Very informative!

Watched the entire video and I'll summarize for those who don't wanna watch the full video....TRUST THE DAMN BOAT Its Designed to work

I would also like to see a video explaining displacement as it relates to your designs.

Excellent....thanks!

Built and registered a homemade vessel. Not once did I have to show anyone floation or have it inspected by anyone.

Mr. Spira please, I had read a brief comment you did once in facebook about your system of navigation, I remember was simple and efficient. Can you do a video about? Thanks.

I’m hopeful that you will do more videos or information on the 27 mullet skiff.how seaworthy/ Blue water add on s you may make it different.I would like to build a live aboard 27-28 ft for cruising.with outboard motor set up if possible.

Thanks for the info much appreciated... I have a 22ft fibreglass boat that has wet foam... so if we remove and replace with air compartments only if water gets into one of these compartments how can we get the water to get to the back drain plugs?

I was in a small pontoon with a few people following the Branson Belle, on Table Rock Lake, the bow sunk to a depth where the front deck was awash. Once the pontoon backed off the Belle it returned to normal. What causes this?

Earlier in the video you said that no matter what you do, water will get in and rot your framing (if you don't drain it out). But at the end of the video you were saying the best flotation is not foam, but trapped air. How can you trap air but not water ?

Thank you Jeff for the information. Question: Do compartments with watertight hatches when used for storage of gear retain most of their buoyancy? I am looking at your 19' Alaskan Grands Bank Dory as a possible camp cruiser and would like to plan gear storage. Thank you for any advice.

At 5:20 you say people think the boats "float higher" with flotation. What about a boat that is swamped (i.e. a small sailing dinghy that flipped and has been righted). Can you "float" the gunwales high enough that you can bail or pump out the boat? Thanks.

Commandants Publication=CMDTPUB.

So is your recommendation for the flat bottom boats (no self bailing decks) to just have a drain plug at the back for when your done boating for the day or do you want a bilge pump near the stern too? Then ping pong balls for flotation? They burn pretty quick. kzfaq.info/get/bejne/mM2IjM-rsM2skpc.html I figure I would need around 4500 balls to get me over 305 lbs of net buoyant force for a 50 hp and 2 batteries. That above video is 5000 of them burning. No fun.

Dont long speaking..just must go on how to built boat..so bored long watch speaking..
