Re: Porta-bote haters: what's not to like?

Mike,
Over or under the life lines? Or do you drop them?
I might be able to do it without life lines but no way (I can imagine) with.

I drop the lifelines. No way could I lift it over manually. I'm no where near that strong.

My technique is to drop the lifelines at the pulpit (I have a simple clip there). Then I pull the bow of the bote up from the water to the foredeck, using the bote painter. This leaves the stern floating in the water. From there I can grab first the front, then the middle seats, and just pull it up over the toerail.

The initial part of the lift is the hardest, but once it gets 1/2 way over the toerail it's more about leverage. I usually do this by myself, although sometimes my partner (Ann) is there to assist, which makes it even easier.

Mike,

Whew!!! You had me worried that I was really off my game!

We may rejigger my life lines to allow that.

Would also facilitate assembly/disassembly.

I know I look all muscular and brutish ... but I'm really not .

We assemble/disassemble on our foredeck with the lifelines down. It would be harder to do it with the lines in place. Getting the bote in the water is also the reverse of hauling up; I just slide the stern over the toerail (lifelines down). Just be sure to grab the painter as the bow is going by .

Re: Porta-bote haters: what's not to like?

Skip.

I made a similar reinforcement for the oar locks. I think the longitudinal aluminum bar along the black plastic "cap rail" I used is is longer than yours but I still get a lot of intolerable flex of the boat sides as I row. It flexes at the end of the reinforcing bar now. Its worse the warmer it is.

Do you still have considerable flex of the boat sides when you row with those long sweeps?

I suppose I could reduce the flex by running the reinforcing bar all along the side of the bote, but the curve of the bote-side/cap rail would limit that and it would make the bote heavier and harder to fold. I'm just wondering what your experience is with flexing bote sides as you row.

It's all in the form. When I was teaching sliding seat rowing to new customers of Indian River Marine shells and dories, I cautioned the typical newbies to concentrate entirely on form before putting in any power as power exacerbates any errors.

So what I would do is make sure that you are in whatever position you prefer(I used my knee patella joint locked into the seat aft of me for the reverse thrust, e.g.), and then do just paddling-strength movement of your arms (and feathering, if that's how you are rowing - and, ideally, the side-view would not be the typical rowboat circle, but a pretty tight rectangular box - up at the end, back just enough off the water to avoid crabbing, and down far enough - only - to cover the blade. Both fore and aft strokes should be parallel to the water.). After 100 or so consecutive strokes without any distortion, start adding power in very small steps.

As you continue to add power without distortion (the thrust, to be effective, should all be in a line forward, no L-R or top/bottom rotations), you'll get to the point where the rowlock should rotate on the pin, and nothing else...

Hope that helps.

PS Everything should be relatively relaxed. You can (and might, when you're really exercising) feather with your fingers alone, and the place for your thumbs would be on the end of the handle, not clutching it.

Also, you'll find much more power with wrists, palms, and first joints parallel to the water, wth the last 3 joints carrying the load (think of carrying a bucket of rocks by the bail-handle; you would not normally use the flat of your first joints from the palm to support the load). At least, that's the case for the typical relatively-thin oar handle; if you were on a sweep oar, you likely would involve the first joint just because of the radius of the handle...

Re: Porta-bote haters: what's not to like?

I used mahogany to reinforce the area around the oar locks.

I think Skip and I have the same idea, different material. For me the 1/4” mahogany seems to he working fine. I havent rowed a lot but Enough to see problems, I think.

Re: Porta-bote haters: what's not to like?

Thanks Skip. Thats a lot of technical jargon that I will have to digest. I used to do some sculling as my best friend was a rower for the UW Huskies in the 1970s and he gave me his old 1966 Pocock rowing shell. But I'm a hack with no formal instruction. Unfortunately I've developed bad wrist and hand arthritis and really can't do significant feathering actions any more, it just hurts too much.

The point of feathering is twofold.

First is to minimize wave slap if there is one large enough to cause a "crab" - a violent stopping motion which with the motion forward of the boat could cause it to eject you, or certainly slow or even stop the boat.

The second is nitpicking - less air resistance.

For your purposes, it may not be needed - just raise the oar (lower the handle) sufficiently to clear any waves. But don't make circles - it's inefficient. Rectangles of slightly higher clearance will suffice...

Likely anyone interested will have noticed that my fingers are multi-jointed.

Not any more than anyone else; my numbers were off.

I trust you understood
