No guys, THANK YOU!! Your 2014 support was truly great and we hit our goal by the end of August and exceeded by $1,400 through the rest of the year! We are in our 15th year online now, hopefully, with your generous help we'll continue on for another 10 years to rival the 25 years the the B31 was int...

ALL metal objects that come into contact with raw water should be bonded, especially AC discharge through hull fittings...

Thanks for the heads up on the Newmar link.

Dug, they spin so fast that you cauterize any wound you may get. lol. A handy but lethal tool.

Nope. The multi-tools only vibrate. You want a full rotational 4 1/2" grinder:

Hi all, for those who have removed the aluminum trim from the flybridge, then faired it and painted. How did you get rid of the rivets? Did you drill them out? I am finding they spin. So I am contemplating cutting them off, grinding flush then smashing them into the edge with a hammer and punch the...

CaptPatrick

Derek,

You'd have no problem with height... Without a tower you're under 13 ft on any standard or lowboy trailer. 13 ft is the legal limit.

Be sure to get your own surveyors. Don't trust the owner's/broker's surveyors...

CaptPatrick

Tom,

Before welding, you've got to carefully analyze why the tower joints are cracking and fix that problem. Otherwise the cracks are just going to reappear...

CaptPatrick

Can I use epoxy for bonding and then use poly resin to laminate the whole assembly? ( thickened epoxy to bond, then 2 layers of 1708 with polyester resin over the core)

JH,

Nope! You can stick epoxy to polyester, but polyester will not stick to epoxy...

Bob,

Ed,

A "goose neck", but not a loop. A loop will trap liquid and prevent the venting. Be sure the vent fitting is clean and has a bug screen...

Tom,

On a lowboy trailer, the top of the flybridge to the ground, with windshield, is right at 13'. Add a few inches for a standard 3 axle trailer. With a 1/2 tower, you'll need at least a 20' clearance.

CaptPatrick

Dug,

Simple. Convert the two top ones to studs....

CaptPatrick

Give 'em a try and see how they do...

CaptPatrick

Jimmy,

If you go to 12' X 9", surly you don't need 3 rams per tab????

Brad,

CaptPatrick

Jimmy, Think of cup this way: No cup, you're stroking the blanket with your fingers tips flat. Cup: you're gripping the blanket with in-curved finger tips. The more the cup, the more the grip. Increased cup has a similar action to increasing diameter. At 21" you've used all of your diameter safety m...

CaptPatrick

he does have a set of 20x26 with light cup i can try.

Don't think you'd like them... Might load your engine better, but it'll also kick your idle speed way past your wanted trolling speed. Pitch will increase speed, cup will increase load.

CaptPatrick

Thanks Bruce,

They're good about doing full back ups before maintenance, plus I've just done a forum data back up both locally and on my computer...

CaptPatrick

Server maintenance will occur either tonight, 12 November, 2014, or tomorrow 13 November, 2014 between the hours of 10:00 pm and 3:00 am MDT (UTC/GMT-6) , for the server which hosts bertram31.com. We expect the estimated downtime to be 30 to 45 minutes while the server is rebooted. None of your data...

WC, The stock B31 tank is a vented tank, so cannot be pressurized. The pump draws water from the tank, probably on demand if you're using a modern demand pump. The little plastic pressure tank, if present, only somewhat buffers the frequency of the on/off cycling of the pump. The pump will only appl...

CaptPatrick

I think I'd go smaller... With that power plant you have, you shouldn't have much trouble keeping your nose down, just enough tab to balance your lateral load.

CaptPatrick

Sounds like tabs to me Jimmy... Make double sure that the tabs are all the way up before backing down and watch that lead foot with those barn doors.

CaptPatrick

John,

You should also lock the bulkhead into the boat with #8x1 1/2" screws, faired over with your fillet...

I wonder, how different are the B31 and B46 hulls?!...

Beyond both having pointy and blunt ends, as different as cats and dogs...

Unquestionably... The failure of almost everything is usually attributable to the lack of and/or improper maintenance, or abuse and misuse.

Rod,

I don't have a clue as who manufactured this boat, but I'll bet dollars to donuts that Ray Hunt never designed even a piece of it... Based on the fact that it's roughly 3,000 miles from you & doubtful Hunt, I'd keep looking, at least for something already on the west coast.

Yannis,

King Starboard is a brand name of one manufacturer for high density polyethylene... Just look for marine grade HDPE.
