The b31s raced by Bertram back in the 60s were gas powered and may, at times, have reached as much as 32 kt. Most probably averaged around 28 kt... From Need For Speed There are two primary factors that limit the upper power options for the B31. Most importantly, in my opinion, is that the hull desi...

CaptPatrick

Alex,

Do not exceed 330 hp in the B31. You don't have enought hull/prop clearance for proper loading of a higher hp engine. That's assuming, of course, that you're talking about diesel...

The two main choices are Yanmar and Cummins. Volvo, Perkins, Cat, and others have been used.

A word of caution on black anodization... It fades relatively fast to a blotchy grey/black and will show underlying color.

Wind, wind chill or air going thru radiator ( what ever you want to call it) WILL cause inanimate object to reach ambient temperature that much quicker

LOL... But not when 180º water is flowing through it.

CaptPatrick

What most people don't realize is, that even though the engine is hot, once that cold air strts rolling over the radiator, especially at 60, the wind chill will freeze the radiator right up. Tony, This is a common myth that will probably never die, but wind chill only relates to those mammals that ...

Greg, Starboard would be a bad choice. Too much expansion/contraction for that application. Best material would be high pressure Formica/Pionite style laminate epoxied to a core. Core material could be plywood, Coosa Board, PVC Foam Board, (AZEK), etc... http://www.bertram31.com/bailey/console/guage...

CaptPatrick

Joe,

Since you're replacing the bronze shaft logs with fiberglass, go ahead and grind down the strut and rudder gelcoat and fair bottom with Awlfair. No need to further grind anything else... Awlfair is a 2 part epoxy and will bond to all just fine. Then re-barrier coat.

OK, guys, here's how I'd do it.... First, I don't trust toggle bolts and the deck skin is too thin to use toggles for a chair mount. You need a substantial backing plate and this will give you that without having to tear up the deck. Cut a hole 2" smaller in diameter than the pedestal base. Dig out ...

Rocky, The caps I made for Buddy Boy came from an odd lot at a distributor in WPB, Fl. and probably weren't a standard size.

Sorry Stephan, Bertrams are too good and therefore don't meet the low standards that the government has set forth in the new boating act. You'll be forced to shop through an accepted online broker with a broke dick website and dealing only in bubble boats.

I'm planning to minimize the sink surface to approx. half (if not less)

Never could figure the logic of having 2 sinks in a 31- boat... Last one I did, I eliminated the head sink altogether, leaving only 1 sink in the galley area.

John,

My best on the sound was when Bruce and I delivered a 56' Hatt aftcabin from LI NY down to Palm Beach. Real wild ride across the Pamlico in beam to slop. Got a little better after we turned west into the Albemarle, but dodging crab pots in that slop was a nightmare... What a pig of boat!

CaptPatrick

Bob,

Nope, other than on your dad's boat, never been close, but it's reputation preceeds it and I do know what shallow water, current, and wind do. Could have used the Palmlico Sound as an example, but Peter wouldn't relate to it any more than the GM. Got some real T shirts from the sound...

Yes, pretty much as you've outlined...

Since you won't have access to the underside of the sole, you'll have to screw the flange of the drain down. And, unless your environmental laws are an issue, you can pump gray water directly overboard.

You're welcome and glad to hear you feel obliged...

Good description from another post, by another guy, on another forum... Think of it as an exhaust hood over your stove/oven...it PULLS.

Harry, Don't know about the new stuff, but with all urethane glues, you really need to clean up excess right away. Once it hardens it's a real bitch in tight areas...

It doesn't make sense to pull a combustible mix of air and fuel vapor through an electric motor.

Remove the pump assembly and try the motor. If it spins freely in both directions the problem in the pump. If not the problem is in the motor.

ABYC recommends exhaust blowers for diesel powered boats to help remove carbon monoxide. However, the problem with CO is that it is just about the same weight as air and therefore doesn't concentrate in low spaces like gasoline fumes. What would be more effective would be a CO detector and keeping e...

CaptPatrick

Pete, You are reading correctly... The potential gasoline fumes must be EXHAUSTED , (i.e. sucked out of low lying bilge spaces and discharged outboard). Pumping fresh air in and depending on passive outflow of explosive vapors through a deck vent is marginal assurance of vapor removal at best. Also,...
