Need an e-mail to send to...

Craig Mac

I have some pictures of a boat that did this----at first glance very unnoticeable----but I do think it detracts from the look.

As I can't post pics---send me an e-mail and will send them....

Craig Mac

Pete----what is your plan for the deck? I think I have a GlassTech ---but not sure who is still in business and what they are making.

You may want to check with L & H-----they have done a number of boats using the deck they use on their own 33----it may be a one-piece.

Craig Mac

Not sure about the quest to replace all wood, especially mahogany---seems to have a long lifespan and holds screws/bolts very well.

I do understand the need to add aluminum to beef them up for the higher torque of diesels.....

Craig Mac

For the standard battery box without cover----does anyone use tie downs? I am using Group 27----and they can move around----I looked at
mounting trays but there is just not enough room to mount 2 in the box.

Craig Mac

Peter---are you doing the frames as well?

Craig Mac

My buddy is replacing his dripless logs---what is the brand of choice these days?

Craig Mac

It will be a flybridge and power will be 370 Cummins

Craig Mac

My beds are similar---and both my transmission and oil coolers are too low to access-----are in process of relocating them.

Craig Mac

I noticed on Facebook that Bayliss is working on a 31 refit----can't wait to see the final product.

Craig Mac

I do have the luxury of having a private dock behind my house----if I was in a public marina I would probably rethink it.

Craig Mac

Not sure why you went with keys-----most of the 31's that I have seen have on/off switches and starter buttons.

Craig Mac

I just had Lookout Boat Window Frames---make a flybridge windscreen for me----I did send them my old one.

I think the going rate for turn-key Palm Beach 9/10 is 200--275K There are 2 L & H restorations currently on YachtWorld---MOONTAN & SEA HOTTIE-----well into the 200's----some will probably consider a little light in iron ( 220/250hp)----but I was on the MOONTAN and workmanship and the maintenance ha...

Craig Mac

cant open the pics as well

Craig Mac

Looking to upgrade my Chartplotter that is mounted on the port side of dash----what is the biggest screen that fits?---bracket mounted

not at the boat to measure

Craig Mac

Do you have a budget? gas or diesel? perferred model?

Craig Mac

You could try L & H in Stuart----generally they do total rebuilds---maybe they do repowers.

They have done many 31 Bertrams and their own boats are usually powered with Cummins.

Craig Mac

American has done a few 31’s—I think they did 2 with no windows —it was recently posted on here

Craig Mac

FYI---that's an L & H deck

Craig Mac

No affiliation----Pretty pricey---Nice pics for ideas.....

Craig Mac

I had New Hampshire----which was eventually bought by Geico-----no problem with renewals at the moment.

Craig Mac

Peter ---did you get any pricing on the fiberglass frames?----they look great.

Craig Mac

Peter---if the boat is in the water---you are probably better off to drop it off at Dickson's ---let them pull the motors and whatever else that can be done----then truck it over to Raybo for their work. You will probably have to transport it back to Dickson's for the engine install.

Craig Mac

RIVA 20 & 25

Craig Mac

This is the first time I heard that boats were made at other yards-----with the exception of RIVA in Italy and some license agreement in Australia

Does anybody have knowledge of this?

Craig Mac

A couple of saddle tanks for sale ---if anybody needs some range----not affiliated with this listing.

https://www.ebay.com/itm/114702758908

Craig Mac

Peter----understand you have the smaller tank----just going to the larger tank may resolve a lot of your problems----you won't be able to run the 100 square but 50 miles will not be an issue.

Craig Mac

Jack--thank you for the offer---however I am planning on working with Broadus @ Lookout----I will let the board know how it works out.

Craig Mac

For a one-off---- I guess------I really would like to find someone to do it.

Could a drape mold be made out of foam?

Craig Mac

I still have not been able to source the correct windscreen----even with mine to use as a template----the plexiglass fabricators can not reproduce the unique bubble design-----this requires a drape mold-----Capt Pat went to the trouble to make one---but I can't locate the fabricator he used that may...

Craig Mac

FYI---the 33 L & H is based on a stretched 30 Chris Craft-----they are based in Stuart.

Craig Mac

Those are original motor boxes----

Craig Mac

My understanding is Monel is a stronger material----is it still available? If you went to 1 1/2 and switched to Monel would that be an option?

Craig Mac

Most gas boats have 1 3/8 shafts----I think very early gas boats had 1 1/4 -----some of those early boats were running 1: 1 gears as well.

I believe the struts used with 1 3/8 shafts can be upsized and used for 1 1/2 shafts.

Craig Mac

It's been many years since I fished on a 25-----but never remember it being an issue------definitely better than a 28.

Craig Mac

I never fished a 26 but have fished 31 / 28 / 25------I can tell you the 28 was the worst----pretty sure the 26 hull is very close to the 28.

Craig Mac

Pretty sure Rybovich started using bubbles before Bertram to fit some motor/transmission packages---if it was good enough for them.....

Craig Mac

Is it more economical to buy new rudders or have a shop add material to your original rudders?---I would assume the later.....

Craig Mac

Whats are the advantages/disadvantages of stainless VS bronze material?

Craig Mac

Silverchevy----did you post a pic?---I couldn't see it

Craig Mac

Anyone have a recommended aftermarket battery box-----still have the original fiberglass tray---but the cover is MIA

Craig Mac

Does anybody know or had dealings with?

Fort Walton Beach, Florida 32547

Craig Mac

I had a similar experience with my borg warner transmissions---I traced the problem to the tranny----the detent ball was jamming in the shift lever.

Lubricated it and the problem disappeared.

Craig Mac

Unfortunately they offer 25 & 28 designs--no mention of 31 ---will need to call them--thank you

Craig Mac

Does anyone know a source for a flybridge windscreen?-----I know Capt Pat offered at one time-----I actually bought one from him.

Craig Mac

I would consider other material than starboard, which is very heavy and holds dirt over time and does not hold paint.

I am not sure the material that was used on mine as it was over 20 years ago-----some type of fiberglass or composite----they were painted with Imron to match my boat.

Craig Mac

Again my boat is pretty light---two different travel lifts put it abt 11K lbs--------Borg Warner 1.5:1 reduction---3 blade Michigan Equi-Poise --18 x18--tip cup. 2600 RPM 24 MPH 21 KNT 2800 RPM 26 MPH 22 KNT 3000 RPM 28 MPH 24 KNT 3200 RPM 30 MPH 26 KNT These #'s indicate a very low slip 17-18%-----...

Craig Mac

I have 454 carb motors---and see similar #'s as Stephan---"From 20 to 24 knots I get +- 1 NM/Gal. (2,600 RPMs to 3,100 RPM) for those speeds."----- my boat is also light----even with a full tank mine chines are above the water--- I think weight is the key to get good performance from gas motors----t...

Craig Mac

I second for pics---love the work coming out of Wharton Creek
