Sent the boat to Barcelona New York couple years ago ,thought I might use it again, not. Now I’m moving it to Jamestown New York to a marina I built se...

Starboard is HDPE, high density poly ethylene and will not hold paint or epoxy. It is machine able and available in several colors. Kinda indestructible, commercial fishing guys use it on there decks for dumping there traps, just pressure wash and that’s all they are concerned with. It’s much heavie...

I’m wanting to send my 1970 sport fish down the road on a truck by a professional boat hauler. He wants the top of the flybridge to the keel measurement. I’m sure 100,s were sent down the road over the years and I have also sent mine over the road, but need a new trucker. Any imput would be apprecia...

Did u coat the entire area with the adhesive or just a test area? Coosa has a very fibrous surface and needs to be sealed with epoxy to hold paint,I know the hard way. Try a sample spot, roll on with a paint roller a coat of epoxy, lay the nautilex on top, stretch as tight as possible,epoxy is a gre...

I can email some covering board pics if u haven’t seen them up love, baitwell built in aswell

Marlin

I attached my 5/8” teak covering board with thickened epoxy and lots of clamps. The aft covering board has quite a radius , there is a twist the side boards as well. I followed the Capt's advice, did door skin templates , 45* corners, then copied onto 1/4 “ plywood making more adjustments to the cor...

Pete, great news for u. In case u forgot, u didn’t have to shovel snow when in Stuart Florida ,there are still houses here

Thx, putting in 2 new motors, insurance covered total cost of the one that blew the rods, I was going to have a 2 year old boat with 1 engine at 0 hours and the other at 3000 hours, had to make the boat marketable in the future. Boat out of service till March/ April. Have the 42 margaritavitch in Gr...

Been following the post on your kne issue, hope they finally got it rite. 2 weeks ago off West End, grand Bahama, a rod let go in the 1800 MAN , Strb engine, port engine shut down with the fire system because of all the oil hitting exhaust components, guest spent the nite at sea fortunately in shall...

Peter, looking for a surveyor in Daytona area for the pre purchase inspection, Hull, motors , wiring, sea keeper ,running gear, glass boat so should not hull issues. Any recommendations

Last time I saw him was at Viking in Riviera beach, Florida, he worked there foe a few years

I see u mentioned butt connectors. I never use them as it’s too difficult to trouble shoot electrical problems . I make every connection with only heat shrinkable epoxy filled ring connectors connected to terminal blocks. U can put a multimeter to measure voltage, check continuity quite easily and m...

Marlin

What was the size of the original backing plates, I would duplicate that dimension. The piece u shows look large and unnessary. I think the backing plate functions as a large flat washer to keep the bolts from pulling thru the bottom if u hit something. I glassed in 3/4” coosa with thickened epoxy a...

Marlin

I was advised to put a crossover hose to keep both shafts lubricated even with 1engine off during trolling

Marlin

Steve, think about using starboard if u are only going to do the fastening mechanically, it’s machineable, structurally much tougher tha coosa as coosa comes without further processing. Both products are impervious from water absorption but coolant requires a lot of processing to come up with a fini...

I aggree on Stuart propeller, Ed makes all the struts, rudders shafts for the local boat builders, Merritt, Rybovitch, Willis and understands the dynamics of propulsion. He has made 40 plus sets of 31 Bertram rudders ,he made my 3rd set. Bobby soles sold his business 10 years ago to an investor. My ...

Marlin

I suggest you contact Ed at Stuart Propellor in Stuart FL, he has fabricated 40 plus sets of rudders for 31 Bertram’s and May have made some for 28,s. He designs rudders , struts for all the custom boats built here, Merritt, rybovitch, Willis for example, all high performance / high end fishing boat...

Marlin

The lifting strikes on my 31 are / were hollow filled with foam. I ground thru the arf end of one and watched the water drip out for days. I think they were added to help lift and stabilize the boat in beam seas. They are very thin and long and I would not think they can ever be dried out entirely a...

Marlin

I recently dropped my headliner and there is not enough length fore to aft for rod storage but maybe Strb to port in the foreword area under the “ tub” area as Pat called it, big ,deep area

Marlin

I also followed theCapt,s teaching and built all new deck framing/ supports out of Coosa, templates the tech in 3 pieces, made all 3sections of Corsair and teak on the bench ad installed by screwing up thru the deck framing into th Cossa sub-deck. Large kill/ fish box openings allow me access to tra...

Go up to BOW in Rivera Beach, great selection, I don’t know what your hatch configuration is, give it a try

Marlin

Bob, u will probably change your fishin habits several times once u move to Florida. I live south of palm beach for 20 years and have fished up to Jupiter either trolling for dolphin or kings , periodically kite fishing for sails or what ever chases the bait. My favorite fishing here is bottom fishi...

Marlin

I think there is considerable science behind the tunnel concept. My understanding is the Boat creates a shallower draft because the running gear is raised up into the pockets. I have a 42’ margaritavich that was( desined for jimmy Buffett to cruise shallow waters in the Bahamas )which has gone thru ...

Marlin

Underwater, butCraig brings up a valid point, exhaust pipe size or some other factors may need to be taken into acct. I’m sure others will provide more imput,I’ll see what I can find out

Marlin

I have a 62’ spencer with 1800 mans with underwater exhaust, all u hear ever is bubbling, never any exhaust smell, idle or cruise. They are also great when deep dropping, no smell or spray when backing into seas. I also have a 31 Bertram with 330 Cummins and side exhaust , have not seen/smelled any ...

Marlin

My 2 cents, I like really dry bilges, mild/mold that tends to grow in the hidden areas of the deck underside, hoses,wiring tend to be unsightly and smelly,probably unhealthy and just dirty. Just this past week I installed a BILGE DRY SYSTEM out of Canada, 375$ Each copy,installed in my 42’ in 3 bilg...

There is a guy,Carlos, that owns a company in Lantana Florida that make windscreens for helicopters. I’ve had him make thicker custom Boat windscreens to meet my specific needs. I don’t like metal handrails/guardrails or brackets and want it strong enough to hang onto in rough seas without breaking....

What’s the downside of a converter, what can’t it do that a 3.5 generator can do, I’m not familiar with the concept, still slugging it out with my nexgen ,would consider turning it into an anchor, extremely loud , I want to run the a/c as I installed it to cool the enclosed 1/2 tower and keep the re...

I think I usedAlex as well,pvc base rail and stainless insert rail?! Couple things the Capt taught me,cut the bow piece first, maybe 6’ Long, heat up with hot air gun to bend the radius around the bow, have help to hold in place till u get some fasteners installed. Butt check the next piece going af...

U have to decide how original u want to keep her, she’s a freshwater boat that nice. It has value based on her originally.

I followed the Capt,s advise and did the Nex gen along port side the Cummins 330, QSB , it has been problematic and a real bitch to service. I cut an inspection hatch / opening into the fiberglass sound shield box, middle of the vertical side, attached 2outer ,1 bottom slides/stop to allow this insp...

I’m all about safe boating and would never consider anything that requires someone to walk out to the bow in bad seas. I control the anchor from the bridge such as the Good system. I would only use the bow anchor in an emergency situation, always work the anchoring from the stern and only in reasona...

Do u have a pulpit

Many boats have filled with rain water ,caused the /cables lift to break, last hurricane did exactly that on n Atlantic in Lantana,I have an email address ,I’ll try it, send u some images of the contraption

My bigger boats don’t have bilge /garboard drains and u need to calculate the gpm of the fluid flow as the gravity bilge drain may not keep up with it, I doubt it would

The trash can may work for a single a/c unit,don’t know, I have 3 a/ c units and 2 refrigeration units that need cooling water on the 42, there are commercial expensive cooling towers we rent when we put the 62’ into her summer out of the water rehab, they are containers as u kinda describe but have...

Steve, I have been cooling my 42, and 31 when they are on the lift by using a pool pump secured to the dock, a piece of 2” pvc attached to a tee onto the suction side of the pump, a check valve threaded on near the bottom end ( replaceable) that is about 12”off the bottom. On the other side of the t...

I was kidding about Pars cyberspace, I just tried to send it yesterday, he told me about the concept

Marlin

Bruce, I wrote a length narrative on how I keep both my boats air conditioned 24/7 on a boat lift with the use of a pool pump. I sent it off and it’s somewhere in Pat,s cyberspace, maybe u can find it in this space,thx

Jerry,s Boat did have a stern type seat aft of the pilot seat,off to the port side as I recall. The Wahoo will be on my lift in a week or so, come take a look and compare

I tried 5200 for this purpose,took some effort but was able to pry it loose,just bought a sheet of starboard, will have scraps and will experiment,thx

Marlin

Couple things, if the f/g sheets are big enough, consider epoxing them directly to 3/4 “ coosa, just have to paint from there. U mentioned starboard for the gutter part, Strb can’t be epoxied, glues, 5200 painted , nothing will stick to my knowledge cause it’s polyethylene. I mention awhile back I h...

My suggestion is to listen to this sage advice, these guys really know this hull,there is probably no one repair shop that has the accumulated experience u are being offered.
