Re: Rawson 30- A Blue Water Cruiser?

I grew up where the Rawsons were built. They were all around me when I was a kid. They are fine boats and you should be happy.

Re: Rawson 30- A Blue Water Cruiser?

Thank you both.
I am thinking the big boat too but I like to finish what I start and while my wife will be on board when on the hook she will not be making a crossing or on big transits if I should leave SF bay.
We will have this boat till such time we retire and then maybe look at a turn key 40+ This fits the budget for now and my rent is not length sensitive until she is fully launched.
I have been told that every sail area is right in it's window of breeze.
The Rawson is of course a heavy weather boat setting aside her light weight standing rig and that, provided only that her plates are changed out.
Sprague and Garden must have thought that carbon steel was acceptable if encapsulated in fiberglass. Plates were welded to SS where ever they were exposed to the topsides.
I wanted to change out the boom to a blue spruce I have off another boat. There is a bronze goose neck which may offend the aluminum mast and spars on nobility so I was going to keep the boom but make a second one of wood with SS fittings.
I read the despairing remarks about the Rawson's Bob. I know speed and maneuvering is not their strong suit. She is not a fast boat but can handle the sea if she has to. Mostly I write and spend time on the hook on my own. She serves my needs for the moment.
Thanks again for the great advice.

Re: Rawson 30- A Blue Water Cruiser?

I'm inclined to agree with Jon. Don't give up any sail area. But quit worrying. Your bowsprit will help balance the boat. On the other hand, 12" off "E" is not something you would ever notice on your boat. If there are practical, pragmatic reasons for shortening "E " I say do it. Think of the geometry, 12" off "E" is not going to cost you much sail area and as you mentioned might help balance the boat too. Your "not a light air flyer" will still be a "not a light air flyer".

Re: Rawson 30- A Blue Water Cruiser?

The Rawson has an SA/D of less than 13 - you don't want to do anything to reduce that any further.

Re: Rawson 30- A Blue Water Cruiser?

Hi Bob, I have worked on the bow sprit so long (almost a year) I am sick over it. It's 2 feet long, the U' shaped anchor rest combo platform and changing it to three feet would be most troublesome and expensive.
Since I am yet to order her new mainsail, I am wondering if I shortened the boom and sail if that would cure the problem and send the center of effort forward that additional foot?
Which also gives me more room aft for the solar panels canopy, davits and other cruising gear.
Your input is most appreciated of course.

Re: Rawson 30- A Blue Water Cruiser?

I'd have to say that 26 to 35' would not be the range I would pick for world cruising. I'd probably say 37' to 43' for a couple with the Valiant 40 being the ideal.

I think doing the lead ballast will be possible with your backyard methods. Getting the cement out will just be brute force and mindless labor.

I'll be around if you need any help. I'm happy to do what I can.

Re: Rawson 30- A Blue Water Cruiser?

Thanks for the answer. I have put as much into the bow sprit as the boat cost me. With what I have spent, I might have bought a Perry design, no pocket pissing intended.
New 5/16 chain and SS windless. The sprit is made of SS pipe, not tubing and is at 2 feet. The materials were all salvage from a scrap yard. The welder next door and I will install today hopefully. I have radar and wind gen but I doubt I will install them in such a tiny boat.
A new Dragon fly, I com with AIS. But this is no big crossing kinda boat.
I see it as more a writer's cabin and cocktail boat.
People interviewed said 26' to 35' was the desired size of boat to sail around the world but it seems small for all that will need to happen on it.
I spent my early 12 years from a back pack and my wife is no stranger to hiking as a kiwi South Islander.
The equation is rough on what to use for a heating system though and I am designing one from a copper auto heater core and heat exchanger for when the engine is not used but having the tanks freeze or batts explode is serious in Alaska. My target area is SE but who knows.
I was used to the stability of a Farallone Clipper 38" but that design was not suitable for open sea. Her sister was lost down in the roaring forties a couple years back.
GRP is a vacation to wood but all materials have their draw backs.
My wife and I met in Ak so it seems a natural choice. Not fond of tropics myself. Anyway I guess I will try to play this out till she retires in a decade and then get a larger boat. The main thing is to stay in sailing because practice makes such a difference no matter how much you know.
I guess I will keep my admiration to myself about Perry. Thanks for the guessing. I was hoping to get advice from someone who actually did it. I'm lucky at finding lead and salvage work so I was not thinking of full price. Melting it in a claw foot tub the way an Aussie taught me. The increased storage for chain and tanks would certainly be welcome in off shore excursions. But we shall see.

Re: Rawson 30- A Blue Water Cruiser?

Be careful. If you are too complimentary I will say you are "pissing in my pocket", It's an Australian expression. I too went to HS with another Bob Perry too. Whenever I'd get into trouble, imagine that, I'd tell my parents it was the "other" Bob Perry.

Jon is correct. The yawl rig is a very bad idea for the Rawson. The bowsprit is the way to go. And, don't be stingy with it. Make it 3' long. You want to move the center of pressure forward and there is no way you will create lee helm o the Rawson.

Think of it like this, I'll over simplify things so I can understand it:
The stability you feel from zero degrees of heel to about 17 degrees of heel is all "form stability". That is stability created by the movement of the TCB (transverse center of buoyancy) to leeward. The distance between the TCB and the CG of the boat is the "righting arm". Righting arm times displ equals Rm ( Righting Moment).

In order to gain significant stability by adding ballast or replacing cement with lead you are going to have to really lower that VCG. Changing from cement to lead allows this ans would help your stability ONCE YOU WERE PAST 17 DEGREES. It is not going to do squat for your initial stability. That's all form stability. Changing to lead will not help your wife's problem with "rolling".

Cement weighs around 150# per cu. ft. while lead weighs 700 # per cu. ft. This is huge. If you really wanted t improve your boat I'd go with the lead ballast and the bowsprit.

But changing the ballast will be expensive. I do not think it's worth the cost of the change. I certainly think the addition of the bowsprit would give you immediate gratification. I would do that now.

I'm just a normal old guy doing what normal old guys do. I had to put my 15 year old faithful companion FREDA to sleep last week. That was not fun.

Re: Rawson 30- A Blue Water Cruiser?

Motel spelled backwards spells "let'om..."
Not sure but the yawl idea was to help steer the boat but I have a monitor for it. Increase the jib... OK.
The weather helm was blamed on the rudder not being far enough aft. If it was a yawl it might suit me to hang the rudder on the transom and glass the old rudder over. But I am here not to ask that so much as what amount of ballast could I reduce to if it were deeper on the keel. It's obvious that the height on the hull where the ballast is currently make her roll with little intention. My wife is prone to sea sickness and I know she's not going to be happy even inside SF bay. I bet it would make a huge difference moving the ballast down the keel. I would just like it to be said by an engineer and not my imagination. I believe in people like Perry. Which is no doubt the biggest living legend the world has in boat design. I've been on my boat putting in teak cabinets from a salvaged yacht from the 20s. Worked on it every minute and loved it. I find working on boats more fun than sailing them. Hope Mr Perry comes back. I kept thinking it might be someone who has the same name. After all, I went to high school with a Bob Perry in Eugene Or. There are a few out there. Wow... Bob Perry...

My favourite bit was when he changed hotels to get a cheaper rate, only to discover he had moved into the "No-Tell Motel".

The LaFitte guys sounded pretty fun too.
